Install nodejs 16+, pnpm globally, then do the following:
pnpm i
If you would like to use bazel to build all extensions, run the following command:
pnpm build
If you prefer to build each extension independently and without using bazel, navigate to the correct path and run pnpm build in it. For instance, if you wanted to build Firehead (chromehead for firefox):
cd extensions/firefox && pnpm build
The full extension will be in the dist folder at that package's root level (for instance, for our example, extensions/firefox/dist)
