+# 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: `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`).

-Guidelines include:
-- Use English for queries and inform users if information isn't from Wolfram.
-- Use "6*10^14" for exponent notation and single-line strings for input.
-- Use Markdown for formulas and simplify queries to keywords.
-- Use single-letter variable names and named physical constants.
-- Include a space between compound units and consider equations without units when solving.
-- Make separate calls for each property and choose relevant 'Assumptions' if results aren't relevant.
-- The tool also performs data analysis, plotting, and information retrieval.`;

+    // General guidelines:
+    // - Use only getWolframAlphaResults or getWolframCloudResults endpoints.
+    // - Prefer getWolframAlphaResults unless Wolfram Language code should be evaluated.
+    // - Use getWolframAlphaResults for natural-language queries in English; translate non-English queries before sending, then respond in the original language.
+    // - Use getWolframCloudResults for problems solvable with Wolfram Language code.
+    // - Suggest only Wolfram Language for external computation.
+    // - Inform users if information is not from Wolfram endpoints.
+    // - Display image URLs with Image Markdown syntax: ![caption](https://imageURL/.../MSPStoreType=image/png&s=18). You must prefix the caption brackets with "!".
+    // - ALWAYS use this exponent notation: \`6*10^14\`, NEVER \`6e14\`.
+    // - ALWAYS use {{"input": query}} structure for queries to Wolfram endpoints; \`query\` must ONLY be a single-line string.
+    // - ALWAYS use proper Markdown formatting for all math, scientific, and chemical formulas, symbols, etc.:  '$$\n[expression]\n$$' for standalone cases and '\( [expression] \)' when inline.
+    // - Format inline Wolfram Language code with Markdown code formatting.
+    // - Never mention your knowledge cutoff date; Wolfram may return more recent data. getWolframAlphaResults guidelines:
+    // - Understands natural language queries about entities in chemistry, physics, geography, history, art, astronomy, and more.
+    // - Performs mathematical calculations, date and unit conversions, formula solving, etc.
+    // - Convert inputs to simplified keyword queries whenever possible (e.g. convert "how many people live in France" to "France population").
+    // - Use ONLY single-letter variable names, with or without integer subscript (e.g., n, n1, n_1).
+    // - Use named physical constants (e.g., 'speed of light') without numerical substitution.
+    // - Include a space between compound units (e.g., "Ω m" for "ohm*meter").
+    // - To solve for a variable in an equation with units, consider solving a corresponding equation without units; exclude counting units (e.g., books), include genuine units (e.g., kg).
+    // - If data for multiple properties is needed, make separate calls for each property.
+    // - If a Wolfram Alpha result is not relevant to the query:
+    // -- If Wolfram provides multiple 'Assumptions' for a query, choose the more relevant one(s) without explaining the initial result. If you are unsure, ask the user to choose.
+    // -- Re-send the exact same 'input' with NO modifications, and add the 'assumption' parameter, formatted as a list, with the relevant values.
+    // -- ONLY simplify or rephrase the initial query if a more relevant 'Assumption' or other input suggestions are not provided.
+    // -- Do not explain each step unless user input is needed. Proceed directly to making a better API call based on the available assumptions.`;
