"description": "Use this when you are working on file operations like reading, writing, scanning, or deleting files. It summarizes the preferred file APIs and patterns used in this repo. It also notes when to use filesystem helpers for directories."
}
Use this when
- Editing file I/O or scans in
backend/cli(the OpenScience CLI package) - Handling directory operations or external tools
Bun file APIs (from Bun docs)
Bun.file(path)is lazy; calltext,json,stream,arrayBuffer,bytes,existsto read.- Metadata:
file.size,file.type,file.name. Bun.write(dest, input)writes strings, buffers, Blobs, Responses, or files.Bun.file(...).delete()deletes a file.file.writer()returns a FileSink for incremental writes.Bun.Glob+Array.fromAsync(glob.scan({ cwd, absolute, onlyFiles, dot }))for scans.- Use
Bun.whichto find a binary, thenBun.spawnto run it. Bun.readableStreamToText/Bytes/JSONfor stream output.
When to use node:fs
- Use
node:fs/promisesfor directories (mkdir,readdir, recursive operations).
Repo patterns
- Prefer Bun APIs over Node
fsfor file access. - Check
Bun.file(...).exists()before reading. - For binary/large files use
arrayBuffer()and MIME checks viafile.type. - Use
Bun.Glob+Array.fromAsyncfor scans. - Decode tool stderr with
Bun.readableStreamToText. - For large writes, use
Bun.write(Bun.file(path), text).
Quick checklist
- Use Bun APIs first.
- Use
path.join/path.resolvefor paths. - Prefer promise
.catch(...)overtry/catchwhen possible.
