Instructions: After EVERY checkbox, test that it works by visiting the HTTP endpoint URL (look it up via Val Town MCP). Mark ✅ by editing this file in Val Town only after confirming it works.

• Remove from README.md all the functions documented in _tests.ts (look up endpoint URL via MCP)
• Add JSDoc to serveFile → Test: appears in docs, remove from README.md
• Add JSDoc to getContentType → Test: appears in docs, remove from README.md
• Add JSDoc to parseVal → Test: appears in docs, remove from README.md
• Add JSDoc to isMain → Test: appears in docs, remove from README.md
• Add JSDoc to testServer → Test: appears in docs, remove from README.md
• Add JSDoc to fetchTranspiledJavaScript → Test: appears in docs, remove from README.md
• Add JSDoc to staticHTTPServer → Test: appears in docs, remove from README.md
• Are there any functions left documented in README.md? If so, add them to this list and move them to JSDoc
• Add target="top" to all links to "val.town"
• Fix the readFile type to take two strings and return a Promise of string or undefined.
• Add js syntax highlighting for the function signature and the example. Strip the ts from the example
• Add precise type information for all inputs and outputs. Users should know exactly every field of every input and every output type.
• Improve the placement of the view source link - it should be directly under the function's name header. It should just say "view source"
• The view source link should link to the whole function range, not just the first line.
• Linkify all the function names with hash-based id links
• Add a left panel sidebar table of contents thing, organized by category, inspired by lodash
• At the top of the docs, link to the utils val
• At the top of the docs, explain the purpose of these vals
• In the read, list file vals, explain how val town doesn't have file access so it can more cheaply and scalably provide a serverless runtime, but you can use these utils which read your val files via the val town api
• Consider linking to all test for each function near its documentation
