This Val Town service fetches JavaScript or TypeScript files from GitHub repositories or Gists and serves them with the proper content type headers (application/javascript).

To fetch a file from a GitHub repository:

/github/:owner/:repo/:branch/:path

Example:

/github/microsoft/TypeScript/main/lib/typescript.js

To fetch a file from a GitHub Gist:

/gist/:gistId/:filename

Example:

/gist/a1b2c3d4e5f6g7h8i9j0/example.js

The service automatically sets the appropriate content type header based on the file extension:

• .js, .mjs, .cjs: application/javascript
• .ts, .tsx, .jsx: application/javascript (TypeScript files are served as JavaScript)
• .json: application/json
• Other file types: text/plain

• CORS enabled (Access-Control-Allow-Origin: *)
• Caching (Cache-Control: public, max-age=3600)
• Error handling for invalid URLs or unavailable files

• Only GET requests are supported
• Files are served as-is without any transformation or transpilation
• GitHub API rate limits may apply
