Readme
atomic-fs-blob-store
blob store that atomically stores blobs (e.g. no partial writes) on the local file system.
Forked from fs-blob-store
npm install atomic-fs-blob-store
Usage
var fs = require('atomic-fs-blob-store')
var blobs = fs('some-directory')
var ws = blobs.createWriteStream({
key: 'some/path/file.txt'
})
ws.write('hello world\n')
ws.end(function() {
var rs = blobs.createReadStream({
key: 'some/path/file.txt'
})
rs.pipe(process.stdout)
})
Atomicity
The original fs-blob-store
doesn't make atomic writes which may lead
to partially written files when an error occurs or if the process
crashes.
atomic-fs-blob-store
guarantees write atomicity, which means that if
your process crashes in the middle of a write, the file won't be written
at all.
Which mean that a key only starts to exist and becomes available for reading once a write is fully completed.
