\n\n---\n\n## File Operations\n\nUtilities for reading and managing files in Val Town Projects.\n\n### `readFile`\n\nReads the contents of a file from the current val.\n\n**Signature:**\n\n```ts\nreadFile(path: string, metaImportUrl?: string): Promise\n```\n\n**Parameters:**\n\n- `path` - The file path to read (with or without leading slash)\n- `metaImportUrl` - Optional. The import.meta.url to determine which val to read\n from. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { readFile } from \"https://esm.town/v/std/utils/index.ts\";\n\n// Most common usage - reads from current val\nconst content = await readFile(\"/README.md\");\nconsole.log(content);\n\n// Explicit val specification\nconst content2 = await readFile(\"/README.md\", import.meta.url);\nconsole.log(content2);\n```\n\n### `listFiles`\n\nLists all files in the current val with their metadata.\n\n**Signature:**\n\n```ts\nlistFiles(metaImportUrl?: string): Promise\n```\n\n**Parameters:**\n\n- `metaImportUrl` - Optional. The import.meta.url to determine which val to list\n files from. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { listFiles } from \"https://esm.town/v/std/utils/index.ts\";\n\n// Most common usage - lists files from current val\nconst files = await listFiles();\nfiles.forEach((file) => console.log(file.path));\n\n// Explicit val specification\nconst files2 = await listFiles(import.meta.url);\nfiles2.forEach((file) => console.log(file.path));\n```\n\n### `listFilesByPath`\n\nLists files in a specific directory path within the current val.\n\n**Signature:**\n\n```ts\nlistFilesByPath(path: string, metaImportUrl?: string): Promise\n```\n\n**Parameters:**\n\n- `path` - The directory path to list files from\n- `metaImportUrl` - Optional. The import.meta.url to determine which val to list\n files from. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { listFilesByPath } from \"https://esm.town/v/std/utils/index.ts\";\n\n// List files in a specific directory\nconst frontendFiles = await listFilesByPath(\"frontend/\");\nfrontendFiles.forEach((file) => console.log(file.path));\n```\n\n### `httpEndpoint`\n\nGets the HTTP endpoint URL for a specific file in the val.\n\n**Signature:**\n\n```ts\nhttpEndpoint(path: string, metaImportUrl?: string): Promise\n```\n\n**Parameters:**\n\n- `path` - The file path to get the endpoint for\n- `metaImportUrl` - Optional. The import.meta.url to determine which val the\n file belongs to. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { httpEndpoint } from \"https://esm.town/v/std/utils/index.ts\";\n\n// Get the HTTP endpoint for a specific file\nconst endpoint = await httpEndpoint(\"/api/users.ts\");\nconsole.log(endpoint); // Returns the full HTTP URL for the endpoint\n```\n\n### `emailAddress`\n\nGets the email address for a file with an email trigger in the val.\n\nNote: that function does not work for vanity email addresses. It only works for\nthe uuid version, because that info isn't in our API yet.\n\n**Signature:**\n\n```ts\nemailAddress(path: string, metaImportUrl?: string): Promise\n```\n\n**Parameters:**\n\n- `path` - The file path to get the email address for\n- `metaImportUrl` - Optional. The import.meta.url to determine which val the\n file belongs to. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { emailAddress } from \"https://esm.town/v/std/utils/index.ts\";\n\n// Get the email address for a file with email trigger\nconst email = await emailAddress(\"/handlers/processEmail.ts\");\nconsole.log(email); // Returns: username-fileid@valtown.email\n```\n\n**Notes:**\n\n- The file must have an email trigger configured\n- Returns email in format: `{username}-{fileIdWithoutDashes}@valtown.email`\n- Throws an error if the file doesn't exist or doesn't have an email trigger\n\n### `fetchTranspiledJavaScript`\n\nFetches and transpiles TypeScript/JavaScript code from esm.town URLs.\n\n**Signature:**\n\n```ts\nfetchTranspiledJavaScript(url: string): Promise\n```\n\n**Example:**\n\n```ts\nimport { fetchTranspiledJavaScript } from \"https://esm.town/v/std/utils/index.ts\";\n\nconst code = await fetchTranspiledJavaScript(\n \"https://esm.town/v/std/utils@85-main/index.ts\",\n);\nconsole.log(code);\n```\n\n**Notes:**\n\n- Paths can be specified with or without leading slashes\n- TypeScript files are automatically transpiled to JavaScript\n- Most functions now have optional `metaImportUrl` parameters that default to\n `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`, making them easier to use in most cases\n\n---\n\n## Parse Import Meta\n\nExtract metadata about the currently running Val.\n\n### `parseVal`\n\nParses Val Town metadata from an import.meta.url.\n\n**Signature:**\n\n```ts\nparseVal(importMetaUrl: string): ValMetadata\n```\n\n**Example:**\n\n```ts\nimport { parseVal } from \"https://esm.town/v/std/utils/index.ts\";\n\nconst val = parseVal(import.meta.url);\nconsole.log(val);\n// Output: { owner: \"username\", name: \"valname\", ... }\n```\n\n**Prior Art:**\n\n- [@pomdtr/extractValInfo](https://www.val.town/v/pomdtr/extractValInfo)\n- [@easrng/whoami](https://www.val.town/v/easrng/whoami)\n\n## Serve File\n\nHTTP utilities for serving val files with proper content types.\n\n### `serveFile`\n\nServes a file from the val as an HTTP Response with the correct Content-Type\nheader.\n\n**Signature:**\n\n```ts\nserveFile(path: string, metaImportUrl?: string): Promise\n```\n\n**Parameters:**\n\n- `path` - The file path to serve\n- `metaImportUrl` - Optional. The import.meta.url to determine which val to\n serve from. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { serveFile } from \"https://esm.town/v/std/utils/index.ts\";\n\n// In a Hono app - most common usage\napp.get(\"/assets/*\", async (c) => {\n return await serveFile(c.req.path);\n});\n\n// Explicit val specification\napp.get(\"/assets/*\", async (c) => {\n return await serveFile(c.req.path, import.meta.url);\n});\n```\n\n### `getContentType`\n\nDetermines the appropriate MIME type for a file based on its extension.\n\n**Signature:**\n\n```ts\ngetContentType(path: string): string\n```\n\n**Example:**\n\n```ts\nimport { getContentType } from \"https://esm.town/v/std/utils/index.ts\";\n\nconsole.log(getContentType(\"index.html\")); // \"text/html; charset=utf-8\"\nconsole.log(getContentType(\"script.ts\")); // \"text/javascript\"\nconsole.log(getContentType(\"data.json\")); // \"application/json; charset=utf-8\"\n```\n\n**Features:**\n\n- TypeScript/TSX/JSX files are served as `text/javascript`\n\n---\n\n## Static HTTP Server\n\nCreate a complete static file server with minimal configuration.\n\n### `staticHTTPServer`\n\nCreates a Hono-based HTTP server that serves static files from your val. The\nserver automatically serves `/index.html` for root requests and handles all\nother file paths.\n\n**Signature:**\n\n```ts\nstaticHTTPServer(importMetaURL?: string): (request: Request) => Promise\n```\n\n**Parameters:**\n\n- `importMetaURL` - Optional. The import.meta.url to determine which val to\n serve files from. Defaults to `Deno.env.get(\"VALTOWN_ENTRYPOINT\")`\n\n**Example:**\n\n```ts\nimport { staticHTTPServer } from \"https://esm.town/v/std/utils/index.ts\";\n\n// Most common usage - serves files from current val\nexport default staticHTTPServer();\n\n// Explicit val specification\nexport default staticHTTPServer(import.meta.url);\n```\n\n**Features:**\n\n- Automatically serves `/index.html` for root path requests (`/`)\n- Handles all file paths with proper content types\n- Built on Hono for reliable HTTP handling\n- Includes error unwrapping for better debugging\n- Returns a fetch-compatible handler function\n\n**Use Cases:**\n\n- Single-page applications (SPAs)\n- Static websites\n- Documentation sites\n- Asset serving for web applications\n\n**Notes:**\n\n- The server will attempt to serve `/index.html` for root requests\n- All other paths are served as-is from the val's file system\n- Non-existent files will throw \"Failed to fetch file\" errors\n- The returned function is compatible with Val Town's HTTP trigger system\n\n---\n\n## Entry Point Detection\n\nUtility for determining if the current file is the main entry point.\n\n### `isMain`\n\nChecks if the current file is the main entry point of the val. This is a\nreplacement for `import.meta.main` which is not available in Val Town's\nenvironment.\n\n**Signature:**\n\n```ts\nisMain(importMetaURL: string): boolean\n```\n\n**Parameters:**\n\n- `importMetaURL` - The `import.meta.url` of the current file\n\n**Example:**\n\n```ts\nimport { isMain } from \"https://esm.town/v/std/utils/index.ts\";\n\nif (isMain(import.meta.url)) {\n console.log(\"This file is being run directly\");\n // Run main logic here\n} else {\n console.log(\"This file is being imported\");\n // Export functions/classes for use by other files\n}\n```\n\n**Use Cases:**\n\n- Conditional execution of code only when file is run directly\n- Separating library code from executable code in the same file\n- Testing and development workflows\n- Creating dual-purpose files that can be both imported and executed\n\n**Notes:**\n\n- This function compares the provided `import.meta.url` with the\n `VALTOWN_ENTRYPOINT` environment variable\n- In Val Town, the entry point is determined by which file is being executed\n directly (e.g., via HTTP trigger, cron, or manual execution)\n- This is equivalent to Python's `if __name__ == \"__main__\":` pattern or\n Node.js's `require.main === module`\n- Unlike Deno's `import.meta.main`, this works reliably in Val Town's serverless\n
