Configuration

TeXlyre uses a centralized configuration system that generates runtime files from a single source of truth: texlyre.config.ts.

Configuration Files

Source Configuration

texlyre.config.ts - The primary configuration file defining all application settings, properties, and plugin registrations. This file serves as the single source of truth for your TeXlyre instance.

Generated Files

The following files are automatically generated from texlyre.config.ts:

• plugins.config.js - Plugin registry used at runtime
• userdata.json - Default user settings and properties
• userdata.local.json - Local development overrides (when userdata.local is defined)

Automatic Overwrites

Running npm run start or npm run generate-configs will completely overwrite the following files:

• plugins.config.js
• userdata.json
• userdata.local.json

Any manual changes to these files will be lost. Always edit texlyre.config.ts instead.

Configuration Structure

Basic Metadata

const config: TexlyreConfig = {
  title: 'TeXlyre',
  tagline: 'A local-first LaTeX & Typst collaborative web editor',
  url: 'https://texlyre.github.io',
  baseUrl: '/texlyre/',
  organizationName: 'texlyre',
  projectName: 'texlyre',
  favicon: '/src/assets/images/TeXlyre_notext.png',
  // ...
};

Plugin Configuration

Register plugins by category. All plugin paths are relative to the extras directory:

plugins: {
  collaborative_viewers: ['bibtex'],
  viewers: ['bibtex', 'image', 'pdf'],
  renderers: ['pdf', 'svg', 'canvas'],
  loggers: ['latex_visualizer', 'typst_visualizer'],
  lsp: [],
  backup: ['github'],
  themes: ['texlyre_slim', 'texlyre_wide', 'texlyre_mobile'],
}

User Data Configuration

Define default settings and optional local overrides:

userdata: {
  default: {
    settings: {
      editor: {
        fontSize: 'base',
        fontFamily: 'monospace',
        // ...
      },
      // ...
    },
    properties: {
      global: {
        sidebarWidth: 502,
        // ...
      },
    },
    secrets: {},
  },
  local: {
    settings: {
      latex: {
        texliveEndpoint: 'http://localhost:5004',
      },
      // ...
    },
  },
}

Generating Configuration Files

Development

Generate configuration files during development:

npm run generate-configs

This command:

1. Reads texlyre.config.ts
2. Generates plugins.config.js
3. Generates userdata.json from default settings
4. Generates userdata.local.json by merging default with local overrides
5. Updates vite.config.ts with the correct baseUrl
6. Updates index.html with title and favicon

Production Build

The start script automatically runs configuration generation:

npm run start

This executes generate-configs before building the application.

Exporting Custom User Data

You can create custom userdata.json files from your TeXlyre instance:

Step 1: Configure Settings

Customize your settings and properties within the TeXlyre application to match your preferred configuration.

Step 2: Export Account Data

1. Click your profile icon in the top-right corner
2. Select Export Account from the dropdown menu

Step 3: Include Settings

In the export dialog, ensure "Include settings, properties, and encrypted secrets" is checked.

Step 4: Extract Configuration

The downloaded ZIP file contains userdata.json in the root directory. Extract this file to use as your custom configuration.

Manual Secret Cleanup

The exported userdata.json includes encrypted secrets. You must manually set the secrets field to an empty object:

{
  "settings": { /* ... */ },
  "properties": { /* ... */ },
  "secrets": {}
}

Configuration Override

Placing a custom userdata.json in your repository will be overwritten when running:

• npm run start
• npm run generate-configs

To preserve custom configurations, update texlyre.config.ts instead.

Forking and Deployment

GitHub Pages Deployment

When forking TeXlyre for GitHub Pages deployment, the configuration generation process runs automatically.

Step 1: Fork Repository

Fork the TeXlyre repository to your GitHub account.

Step 2: Enable GitHub Pages

Navigate to repository Settings → Pages and configure the deployment source.

Step 3: Configure texlyre.config.ts

Update texlyre.config.ts with your deployment details:

const config: TexlyreConfig = {
  title: 'My TeXlyre Instance',
  url: 'https://yourusername.github.io',
  baseUrl: '/your-repo-name/',
  organizationName: 'yourusername',
  projectName: 'your-repo-name',
  // ...
};

Step 4: Automatic Build Process

The GitHub Actions workflow automatically:

1. Runs npm run generate-configs
2. Overwrites plugins.config.js, userdata.json, and userdata.local.json
3. Builds the application
4. Deploys to GitHub Pages

Production Configuration

The deployment process always regenerates configuration files from texlyre.config.ts. Manual edits to generated files will not persist through deployments.

Custom Domain Configuration

For custom domains, update the url field in texlyre.config.ts:

const config: TexlyreConfig = {
  url: 'https://your-custom-domain.com',
  baseUrl: '/',
  // ...
};

Configuration Workflow

Recommended Workflow

1. Edit texlyre.config.ts with desired changes
2. Run npm run generate-configs to update generated files
3. Test changes locally with npm run dev
4. Commit both texlyre.config.ts and generated files
5. Deploy using npm run start or GitHub Actions

Local Development Overrides

Use the local configuration block for development-specific settings:

userdata: {
  default: {
    settings: {
      latex: {
        texliveEndpoint: 'https://texlive.emaily.re',
      },
    },
  },
  local: {
    settings: {
      latex: {
        texliveEndpoint: 'http://localhost:5004',
      },
    },
  },
}

This generates:

• userdata.json with production endpoints
• userdata.local.json with local development endpoints

Troubleshooting

Configuration Not Applied

If configuration changes don't appear:

1. Verify texlyre.config.ts syntax is valid
2. Run npm run generate-configs manually
3. Clear browser cache and reload
4. Check browser console for configuration errors

Plugin Not Loading

Ensure plugins are:

1. Registered in texlyre.config.ts under the correct category
2. Located in the extras directory with correct paths
3. Properly exported and implementing required interfaces

Build Failures

If builds fail after configuration changes:

1. Validate TypeScript types in texlyre.config.ts
2. Ensure all referenced plugins exist
3. Check that baseUrl and other paths are valid
4. Review GitHub Actions logs for specific errors
