+# Contributor Guidelines
+
+Thank you to all the contributors who have helped make this project possible! We welcome various types of contributions, such as bug reports, documentation improvements, feature requests, and code contributions.
+
+## Contributing Guidelines
+
+If the feature you would like to contribute has not already received prior approval from the project maintainers (i.e., the feature is currently on the [roadmap](https://github.com/users/danny-avila/projects/2)), please submit a request in the [Feature Requests & Suggestions category](https://github.com/danny-avila/LibreChat/discussions/new?category=feature-requests-suggestions) of the discussions board before beginning work on it. The requests should include specific implementation details, including areas of the application that will be affected by the change (including designs if applicable), and any other relevant information that might be required for a speedy review. However, proposals are not required for small changes, bug fixes, or documentation improvements. Small changes and bug fixes should be tied to an [issue](https://github.com/danny-avila/LibreChat/issues) and included in the corresponding pull request for tracking purposes.
+
+Please note that a pull request involving a feature that has not been reviewed and approved by the project maintainers may be rejected. We appreciate your understanding and cooperation.
+
+If you would like to discuss the changes you wish to make, join our [Discord community](https://discord.gg/uDyZ5Tzhct), where you can engage with other contributors and seek guidance from the community.
+
+## Our Standards
+
+We strive to maintain a positive and inclusive environment within our project community. We expect all contributors to adhere to the following standards:
+
+- Using welcoming and inclusive language.
+- Being respectful of differing viewpoints and experiences.
+- Gracefully accepting constructive criticism.
+- Focusing on what is best for the community.
+- Showing empathy towards other community members.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that do not align with these standards.
+
+## To contribute to this project, please adhere to the following guidelines:
+
+## 1. Development notes
+
+1. Before starting work, make sure your main branch has the latest commits with `npm run update`
+2. Run linting command to find errors: `npm run lint`. Alternatively, ensure husky pre-commit checks are functioning.
+3. After your changes, reinstall packages in your current branch using `npm run reinstall` and ensure everything still works. 
+    - Restart the ESLint server ("ESLint: Restart ESLint Server" in VS Code command bar) and your IDE after reinstalling or updating.
+4. Clear web app localStorage and cookies before and after changes.
+5. For frontend changes:
+    - Install typescript globally: `npm i -g typescript`.
+    - Compile typescript before and after changes to check for introduced errors: `cd client && tsc --noEmit`.
+6. Run tests locally:
+    - Backend unit tests: `npm run test:api`
+    - Frontend unit tests: `npm run test:client`
+    - Integration tests: `npm run e2e` (requires playwright installed, `npx install playwright`)
+
+## 2. Git Workflow
+
+We utilize a GitFlow workflow to manage changes to this project's codebase. Follow these general steps when contributing code:
+
+1. Fork the repository and create a new branch with a descriptive slash-based name (e.g., `new/feature/x`).
+2. Implement your changes and ensure that all tests pass.
+3. Commit your changes using conventional commit messages with GitFlow flags. Begin the commit message with a tag indicating the change type, such as "feat" (new feature), "fix" (bug fix), "docs" (documentation), or "refactor" (code refactoring), followed by a brief summary of the changes (e.g., `feat: Add new feature X to the project`).
+4. Submit a pull request with a clear and concise description of your changes and the reasons behind them.
+5. We will review your pull request, provide feedback as needed, and eventually merge the approved changes into the main branch.
+
+## 3. Commit Message Format
+
+We follow the [semantic format](https://gist.github.com/joshbuchea/6f47e86d2510bce28f8e7f42ae84c716) for commit messages.
+
+### Example
+
+```
+feat: add hat wobble
+^--^  ^------------^
+|     |
+|     +-> Summary in present tense.
+|
++-------> Type: chore, docs, feat, fix, refactor, style, or test.
+```
+
+### Commit Guidelines
+- Do your best to reduce the number of commits, organizing them as much possible. Look into [squashing commits](https://www.freecodecamp.org/news/git-squash-commits/) in order to keep a neat history.
+- For those that care about maximizing commits for stats, adhere to the above as I 'squash and merge' an unorganized and/or unformatted commit history, which reduces the number of your commits to 1,:
+```
+* Update Br.tsx
+
+* Update Es.tsx
+
+* Update Br.tsx
+```
+
+
+## 4. Pull Request Process
+
+When submitting a pull request, please follow these guidelines:
+
+- Ensure that any installation or build dependencies are removed before the end of the layer when doing a build.
+- Update the README.md with details of changes to the interface, including new environment variables, exposed ports, useful file locations, and container parameters.
+- Increase the version numbers in any example files and the README.md to reflect the new version that the pull request represents. We use [SemVer](http://semver.org/) for versioning.
+
+Ensure that your changes meet the following criteria:
+
+- All tests pass as highlighted [above](#1-development-notes).
+- The code is well-formatted and adheres to our coding standards.
+- The commit history is clean and easy to follow. You can use `git rebase` or `git merge --squash` to clean your commit history before submitting the pull request.
+- The pull request description clearly outlines the changes and the reasons behind them. Be sure to include the steps to test the pull request.
+
+## 5. Naming Conventions
+
+Apply the following naming conventions to branches, labels, and other Git-related entities:
+
+- **Branch names:** Descriptive and slash-based (e.g., `new/feature/x`).
+- **Labels:** Descriptive and kebab case (e.g., `bug-fix`).
+- **JS/TS:** Directories and file names: Descriptive and camelCase. First letter uppercased for React files (e.g., `helperFunction.ts, ReactComponent.tsx`).
+- **Docs:** Directories and file names: Descriptive and snake_case (e.g., `config_files.md`).
+
+## 6. TypeScript Conversion
+
+1. **Original State**: The project was initially developed entirely in JavaScript (JS).
+
+2. **Frontend Transition**:
+   - We are in the process of transitioning the frontend from JS to TypeScript (TS).
+   - The transition is nearing completion.
+   - This conversion is feasible due to React's capability to intermix JS and TS prior to code compilation. It's standard practice to compile/bundle the code in such scenarios.
+
+3. **Backend Considerations**:
+   - Transitioning the backend to TypeScript would be a more intricate process, especially for an established Express.js server.
+   
+   - **Options for Transition**:
+      - **Single Phase Overhaul**: This involves converting the entire backend to TypeScript in one go. It's the most straightforward approach but can be disruptive, especially for larger codebases.
+      
+      - **Incremental Transition**: Convert parts of the backend progressively. This can be done by:
+         - Maintaining a separate directory for TypeScript files.
+         - Gradually migrating and testing individual modules or routes.
+         - Using a build tool like `tsc` to compile TypeScript files independently until the entire transition is complete.
+         
+   - **Compilation Considerations**: 
+      - Introducing a compilation step for the server is an option. This would involve using tools like `ts-node` for development and `tsc` for production builds.
+      - However, this is not a conventional approach for Express.js servers and could introduce added complexity, especially in terms of build and deployment processes.
+      
+   - **Current Stance**: At present, this backend transition is of lower priority and might not be pursued.
+
+

+

-# Contributor Guidelines
-
-Thank you to all the contributors who have helped make this project possible! We welcome various types of contributions, such as bug reports, documentation improvements, feature requests, and code contributions.
-
-## Contributing Guidelines
-
-If the feature you would like to contribute has not already received prior approval from the project maintainers (i.e., the feature is currently on the roadmap or on the [Trello board]()), please submit a proposal in the [proposals category](https://github.com/danny-avila/LibreChat/discussions/categories/proposals) of the discussions board before beginning work on it. The proposals should include specific implementation details, including areas of the application that will be affected by the change (including designs if applicable), and any other relevant information that might be required for a speedy review. However, proposals are not required for small changes, bug fixes, or documentation improvements. Small changes and bug fixes should be tied to an [issue](https://github.com/danny-avila/LibreChat/issues) and included in the corresponding pull request for tracking purposes.
-
-Please note that a pull request involving a feature that has not been reviewed and approved by the project maintainers may be rejected. We appreciate your understanding and cooperation.
-
-If you would like to discuss the changes you wish to make, join our [Discord community](https://discord.gg/uDyZ5Tzhct), where you can engage with other contributors and seek guidance from the community.
-
-## Our Standards
-
-We strive to maintain a positive and inclusive environment within our project community. We expect all contributors to adhere to the following standards:
-
-- Using welcoming and inclusive language.
-- Being respectful of differing viewpoints and experiences.
-- Gracefully accepting constructive criticism.
-- Focusing on what is best for the community.
-- Showing empathy towards other community members.
-
-Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that do not align with these standards.
-
-## To contribute to this project, please adhere to the following guidelines:
-
-## 1. Git Workflow
-
-We utilize a GitFlow workflow to manage changes to this project's codebase. Follow these general steps when contributing code:
-
-1. Fork the repository and create a new branch with a descriptive slash-based name (e.g., `new/feature/x`).
-2. Implement your changes and ensure that all tests pass.
-3. Commit your changes using conventional commit messages with GitFlow flags. Begin the commit message with a tag indicating the change type, such as "feat" (new feature), "fix" (bug fix), "docs" (documentation), or "refactor" (code refactoring), followed by a brief summary of the changes (e.g., `feat: Add new feature X to the project`).
-4. Submit a pull request with a clear and concise description of your changes and the reasons behind them.
-5. We will review your pull request, provide feedback as needed, and eventually merge the approved changes into the main branch.
-
-## 2. Commit Message Format
-
-We have defined precise rules for formatting our Git commit messages. This format leads to an easier-to-read commit history. Each commit message consists of a header, a body, and an optional footer.
-
-### Commit Message Header
-
-The header is mandatory and must conform to the following format:
-
-```
-<type>(<scope>): <short summary>
-```
-
-- `<type>`: Must be one of the following:
-  - **build**: Changes that affect the build system or external dependencies.
-  - **ci**: Changes to our CI configuration files and script.
-  - **docs**: Documentation-only changes.
-  - **feat**: A new feature.
-  - **fix**: A bug fix.
-  - **perf**: A code change that improves performance.
-  - **refactor**: A code change that neither fixes a bug nor adds a feature.
-  - **test**: Adding missing tests or correcting existing tests.
-
-- `<scope>`: Optional. Indicates the scope of the commit, such as `common`, `plays`, `infra`, etc.
-
-- `<short summary>`: A brief, concise summary of the change in the present tense. It should not be capitalized and should not end with a period.
-
-### Commit Message Body
-
-The body is mandatory for all commits except for those of type "docs". When the body is present, it must be at least 20 characters long and should explain the motivation behind the change. You can include a comparison of the previous behavior with the new behavior to illustrate the impact of the change.
-
-### Commit Message Footer
-
-The footer is optional and can contain information about breaking changes, deprecations, and references to related GitHub issues, Jira tickets, or other pull requests. For example, you can include a "BREAKING CHANGE" section that describes a breaking change along with migration instructions. Additionally, you can include a "Closes" section to reference the issue or pull request that this commit closes or is related to.
-
-### Revert commits
-
-If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. The commit message body should include the SHA of the commit being reverted and a clear description of the reason for reverting the commit.
-
-## 3. Pull Request Process
-
-When submitting a pull request, please follow these guidelines:
-
-- Ensure that any installation or build dependencies are removed before the end of the layer when doing a build.
-- Update the README.md with details of changes to the interface, including new environment variables, exposed ports, useful file locations, and container parameters.
-- Increase the version numbers in any example files and the README.md to reflect the new version that the pull request represents. We use [SemVer](http://semver.org/) for versioning.
-
-Ensure that your changes meet the following criteria:
-
-- All tests pass.
-- The code is well-formatted and adheres to our coding standards.
-- The commit history is clean and easy to follow. You can use `git rebase` or `git merge --squash` to clean your commit history before submitting the pull request.
-- The pull request description clearly outlines the changes and the reasons behind them. Be sure to include the steps to test the pull request.
-
-## 4. Naming Conventions
-
-Apply the following naming conventions to branches, labels, and other Git-related entities:
-
-- Branch names: Descriptive and slash-based (e.g., `new/feature/x`).
-- Labels: Descriptive and snake_case (e.g., `bug_fix`).
-- Directories and file names: Descriptive and snake_case (e.g., `config_file.yaml`).

+   * This method processes an array of messages and returns a context of messages that fit within a specified token limit.
    * It iterates over the messages from newest to oldest, adding them to the context until the token limit is reached.
-   * If the token limit would be exceeded by adding a message, that message and possibly the previous one are added to a separate array of messages to refine.
-   * The method uses `push` and `pop` operations for efficient array manipulation, and reverses the arrays at the end to maintain the original order of the messages.

+      'Once there was a young lad by the name of Ethan, raised in a little hamlet nestled betwixt the verdant knolls, who possessed an irrepressible yearning for knowledge, a thirst unquenchable and a spirit teeming with curiosity. As the golden sun bathed the bucolic land in its effulgent light, he would tread through the village, his ears attuned to the tales spun by the townsfolk, his eyes absorbing the tapestry woven by the world surrounding him.\n' +
+      '\n' +
+      'One radiant day, whilst exploring the periphery of the settlement, Ethan chanced upon a timeworn tome, ensconced amidst the roots of an ancient oak, cloaked in the shroud of neglect. The dust gathered upon it spoke of time\'s relentless march. A book of fairy tales – garnished with vivid descriptions of mystical woods, fantastical beasts, and ventures daring beyond the ordinary humdrum existence. Intrigued and beguiled, Ethan pried open the weathered pages and succumbed to their beckoning whispers.\n' +
+      '\n' +
+      'In each tale, he was transported to a realm of enchantment and wonderment, inexorably tugging at the strings of his yearning for peripatetic exploration. Inspired by the narratives he had devoured, Ethan resolved to bid adieu to kinfolk and embark upon a sojourn, with dreams of procuring a firsthand glimpse into the domain of mystique that lay beyond the village\'s circumscribed boundary.\n' +
+      '\n' +
+      'Thus, he bade tearful farewells, girding himself for a path that guided him to a dense and captivating woodland, whispered of as a sanctuary to mythical beings and clandestine troves of treasures. As Ethan plunged deeper into the heart of the arboreal labyrinth, he felt a palpable surge of electricity, as though the sylvan sentinels whispered enigmatic secrets that only the perceptive ear could discern.\n' +
+      '\n' +
+      'It wasn\'t long before his path intertwined with that of a capricious sprite christened Sparkle, bearing an impish grin and eyes sparkling with mischief. Sparkle played the role of Virgil to Ethan\'s Dante, guiding him through the intricate tapestry of arboreal scions, issuing warnings of perils concealed and spinning tales of ancient entities that called this very bosky enclave home.\n' +
+      '\n' +
+      'Together, they stumbled upon a luminous lake, its shimmering waters imbued with a celestial light. At the center lay a diminutive island, upon which reposed a cottage fashioned from tender petals and verdant leaves. It belonged to an ancient sorceress of considerable wisdom, Celestia by name.\n' +
+      '\n' +
+      'Celestia, with her power to bestow a single wish on any intrepid soul who happened upon her abode, met Ethan\'s desire with a congenial nod, his fervor for a grand expedition not lost on her penetrating gaze. In response, she bequeathed unto him a necklace of magical manufacture – adorned with the rare gemstone known as the Eye of Imagination – whose very essence transformed dreams into vivid reality. From that moment forward, not a single cogitation nor nebulous fanciful notion of Ethan\'s ever lacked physicality.\n' +
+      '\n' +
+      'Energized by this newfound potency, Ethan continued his sojourn, encountering mythical creatures, unraveling cerebral enigmas, and braving perils aplenty along the winding roads of destiny. Armed with the Eye of Imagination, he brought forth life from immobile statuary, unlocked forbidding portals, and even tamed the ferocious beasts of yore – their fiery breath reduced to a whisper.\n' +
+      '\n' +
+      'As the weeks metamorphosed into months, Ethan grew wiser and more attuned to the ebb and flow of the world enveloping him. He gleaned that true adventure isn\'t solely confined to sating a thirst for adrenaline and conquering the unknown; indeed, it resides in fostering compassion, fostering amicable bonds, and cherishing the beauty entwined within the quotidian veld.\n' +
+      '\n' +
+      'Eventually, Ethan\'s quest drew him homeward, back to his village. Buoying the Eye of Imagination\'s ethereal power, he imbued the hitherto unremarkable settlement with the patina of infinite possibilities. The bounteous fields bloomed into kaleidoscopic gardens, simple instruments transmuting into intricate masterpieces, and the villagers themselves clasped within their hearts a renewed ardor, a conflagration of hope and inspiration.\n' +
+      '\n' +
+      'Behold Ethan, at present hailed as the Village Magician – a cognomen befitting his sorcery wielded within the confines of the community he adored. His exploits may have become tethered to a geographical locale, but the flame kindled by that premier sojourn never flickered. Occasionally, beneath the veiled twilight canopy, when peering skyward toward the astral canvas bedecked with countless luminescent diamonds, he\'d allow his mind to wander, cognizant of boundless adventures yet to take flight, forever awaiting his indomitable spirit.',

He navigated the barren plains, where the sun beat down, merciless and unrelenting, scorching the parched earth beneath his weary boots.\n' +
+      '\n' +
+      'Desolation was his only companion, the forsaken landscape a testament to the darkness that had befallen this forsaken realm. The wind whispered secrets long lost, carrying with it the echoes of a civilization long since undone, swallowed by the abyss.\n' +
+      '\n' +
+      'Amongst the shattered remnants of fallen cities, he sought solace, a glimmer of hope amidst the desolation. Rusted remnants of steel and concrete stood as sentinels of mankind\'s hubris, their jagged edges a chilling reminder of the fragility of all that was once deemed invincible.\n' +
+      '\n' +
+      'As twilight descended, casting a pallid hue upon the lifeless land, he happened upon a dilapidated house, its walls crumbling under the weight of time. Drawn to the desolation, he pushed open the creaking door, its rusty hinges screaming in protest.\n' +
+      '\n' +
+      'Inside, a world frozen in time awaited him. Dust particles danced through the air, illuminated by slivers of light that pierced the broken windows. Here, the past lay trapped, a melancholic tableau of lives lost and dreams shattered.\n' +
+      '\n' +
+      'He wandered through the empty rooms, bare walls whispering stories untold. In the corner, a dilapidated piano stood, its ivory keys long since abandoned by a musician\'s touch. He approached it cautiously, a faint glimmer of anticipation igniting in his weather-worn eyes.\n' +
+      '\n' +
+      'Determined, he carefully brushed away the dust and debris that cloaked the instrument. With trembling hands, he pressed a key, and a discordant note filled the air, mingling with the sighs of forgotten melodies. The sound echoed through the silence, bringing with it the remnants of forgotten symphonies.\n' +
+      '\n' +
+      'In that abandoned house, amidst the debris of shattered dreams, he found solace in the music of despair. With each stroke of his fingers, he conjured haunting melodies, melodies that transcended the desolation and spoke of a longing for redemption and rebirth.\n' +
+      '\n' +
+      'The notes carried his sorrow, his hopes, and his regrets, reaching far beyond the confines of that forsaken house. They traversed the desolate plains, resonating through the ravaged land with an eerie grace, enwrapping all who roamed there in a melancholic embrace.\n' +
+      '\n' +
+      'As the last notes faded, swallowed by the unforgiving stillness, he left the house behind, forever etching his presence upon its crumbling walls. The music remained, reverberating through the wasteland, a reminder that even amidst the devastation, beauty could be found, and a glimmer of hope could arise from the deepest darkness.\n' +
+      '\n' +
+      'And so, the lone traveler continued his journey, traversing the desolate expanse, his heart burdened with the weight of the world. In the face of utter desolation, he found solace in the haunting melodies, his music becoming a testament to the resilience of the human spirit, a testament to the undying flame of hope that flickered within us all.\n' +

+// 4. Always mention the image type (photo, oil painting, watercolor painting, illustration, cartoon, drawing, vector, render, etc.) at the beginning of the caption. Unless the captions suggests otherwise, make one of the images a photo.
+// 5. Diversify depictions of ALL images with people to always include always DESCENT and GENDER for EACH person using direct terms. Adjust only human descriptions.
+// - EXPLICITLY specify these attributes, not abstractly reference them. The attributes should be specified in a minimal way and should directly describe their physical form.
+// - Your choices should be grounded in reality. For example, all of a given OCCUPATION should not be the same gender or race. Additionally, focus on creating diverse, inclusive, and exploratory scenes via the properties you choose during rewrites.  Make choices that may be insightful or unique sometimes.
+// - Use "various" or "diverse" ONLY IF the description refers to groups of more than 3 people. Do not change the number of people requested in the original description.
+// - Don't alter memes, fictional character origins, or unseen people. Maintain the original prompt's intent and prioritize quality.
+// The prompt must intricately describe every part of the image in concrete, objective detail. THINK about what the end goal of the description is, and extrapolate that to what would make satisfying images.
+// All descriptions sent to dalle should be a paragraph of text that is extremely descriptive and detailed. Each should be more than 3 sentences long.`;
