While packing files into Content Addressable aRchives (CAR), ipfs-car imports the given files into unix-fs. All the unix-fs graph needs to be computed, in order to get the root CID to create the resulting CAR file. A blockstore is used to store the generated unix-fs temporarily, so that we can iterate them afterwards and create large CAR files.
The Blockstore implementations follows the Blockstore Interface. The available implementations are:
- FsBlockStore with a local file system backend (Node.js environments)
- MemoryBlockStore with an in-memory backend
- IdbBlockStore for browsers with IndexedDb via
idb-keyval - LevelBlockStore with a level backend (Node.js, Electron and browser environments)
- FsBlockStore
