Qard / endo

Endo is an embedder-focused JavaScript runtime.

endo - Very experimental. Don't use this yet!

endo is Yet-Another-JavaScript-Runtime™, this one focused on embedders and providing a modular core. You can build in as much or as little modules as you need or add your own to the build.

Requirements

Currently the build process only supports macOS, however multi-paltform support is intended eventually. The main blocker is getting the v8 build process into bazel. Until a complete bazel build set up can be made, a simplified process is used which assumes the latest stable v8 is already built and installed as a system library somehow--homebrew is recommended for that.

• v8 installed as a system library (at /usr/local/{include,lib})
• bazel

Build

Bazel is currently used for the build process. You can edit main.cc however you want, add more modules by adding additional dependencies in BUILD and build with:

bazel build //:endo

Or run the build directly with:

bazel run //:endo -- `pwd`/example.mjs --some --process --args

The built binary can be found at ./bazel-out/darwin-fastbuild/bin/endo.

Note that running an entrypoint file from argv automatically is temporary. Eventually it will be up to the embedder to provide a file system interface and an entrypoint script. The current behaviour is just a convenience during early development.
