@electron/asar is a TypeScript library and CLI for the ASAR archive format, a tar-like format that concatenates files without compression while supporting random access via a JSON index. It is used primarily to package Electron applications, with deduplication of identical file contents and support for unpacking selected files to disk.
Use cases
- package an electron app into an asar archive
- extract files from an asar archive
- list the contents of an asar file
- create archives with random access without compression
- reduce archive size by deduplicating identical files
- exclude certain directories when packing an app
- programmatically create asar archives from node
When to choose
- you are packaging or distributing an Electron application
- you need a simple uncompressed archive format with fast random access and an easy-to-parse JSON header
- you want a CLI plus programmatic API for packing and extracting archives
When to avoid
- you need compression, since asar stores files uncompressed like tar
- you need a general-purpose archive format interoperable with standard tools like tar or zip
- you need robust built-in error handling in the programmatic API
