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
filepath	string	File to act upon.
oid	string	OID of the object in the object database to add to the index with the specified filepath.
mode	number = 100644	The file mode to add the file to the index.
add	boolean	Adds the specified file to the index if it does not yet exist in the index.
remove	boolean	Remove the specified file from the index if it does not exist in the workspace anymore.
force	boolean	Remove the specified file from the index, even if it still exists in the workspace.
cache	object	a cache object
return	Promise<(string | void)>	Resolves successfully with the SHA-1 object id of the object written or updated in the index, or nothing if the file was removed.

Example Code:

await git.updateIndex({
  fs,
  dir: '/tutorial',
  filepath: 'readme.md'
})

// Manually create a blob in the object database.
let oid = await git.writeBlob({
  fs,
  dir: '/tutorial',
  blob: new Uint8Array([])
})

// Write the object in the object database to the index.
await git.updateIndex({
  fs,
  dir: '/tutorial',
  add: true,
  filepath: 'readme.md',
  oid
})

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')
