readBlob

Read a blob object directly

param	type [= default]	description
fs	FsClient	a file system client
dir	string	The working tree directory path
gitdir	string = join(dir,'.git')	The git directory path
oid	string	The SHA-1 object id to get. Annotated tags, commits, and trees are peeled.
filepath	string	Don't return the object with oid itself, but resolve oid to a tree and then return the blob object at that filepath.
cache	object	a cache object
return	Promise<ReadBlobResult>	Resolves successfully with a blob object description

The object returned has the following schema:

type ReadBlobResult = {
  oid: string;
  blob: Uint8Array;
}

Example Code:

// Get the contents of 'README.md' in the main branch.
let commitOid = await git.resolveRef({ fs, dir: '/tutorial', ref: 'main' })
console.log(commitOid)
let { blob } = await git.readBlob({
  fs,
  dir: '/tutorial',
  oid: commitOid,
  filepath: 'README.md'
})
console.log(Buffer.from(blob).toString('utf8'))

Tip: If you need a clean slate, expand and run this snippet to clean up the file system.

window.fs = new LightningFS('fs', { wipe: true })
window.pfs = window.fs.promises
console.log('done')
