@tooling/packherd
Herds all dependencies reachable from an entry and packs them.
Table of Contents
Summary
packherd has three main tasks:
- bundling application files and providing related metadata
- loading modules that have been bundled previously and are provided via fully instantiated module exports or definition functions that return a module export when invoked
- transpiling TypeScript modules on demand and maintaining a cache of them
1. is provided by this package. 2. and 3. are provided by @packages/packherd-require. While 1. and 2. are very related
and work hand in hand, 3. is unrelated to them and was just added here since it is another feature that requires to intercept module loads.
Creating a Bundle with Packherd
Calling the packherd function and providing the desired packherd opts will return the Buffer of the bundle, a meta esbuild metafile, a
Buffer containing the sourceMap if it was generated as well as any warnings that esbuild
emitted.
The caller can then store this data or use it for further operations, i.e. to generate a snapshot as is the case for the v8-snapshot module.
