# pack-ops mixin This mixin adds the ability to consume or create packfile streams. This depends on the repo already having: - `loadRaw(hash) => raw-binary` - `saveRaw(hash, raw-binary) =>` And then adds: - `unpack(stream, opts) => hashes` - `pack(hashes, opts) => stream` The streams are simple-stream format. This means they have a `.read(callback)` method for pulling items out of the stream. Example: ```js var packOps = require('js-git/mixins/pack-ops'); packOps(repo); repo.unpack(stream, opts, function (err, hashes) { // hashes is imported objects }); repo.pack(hashes, opts, function (err, stream) { if (err) throw err; stream.read(onRead); function onRead(err, item) { if (err) throw err; console.log(item); if (item) stream.read(onRead); } }); ```
