// Build the dist/packages-dist directory in the same fashion as the legacy
|
|
// /build.sh script, by building the npm packages with Bazel and copying files.
|
|
// This is needed for scripts and tests which are not updated to the Bazel output
|
|
// layout (which always matches the input layout).
|
|
// Do not add new dependencies on this script, instead adapt scripts to use the
|
|
// new layout, and write new tests as Bazel targets.
|
|
//
|
|
// Ideally integration tests should run under bazel, and just consume the npm
|
|
// packages via `deps`. Until that works, we manually build the npm packages and then
|
|
// copy the results to the appropriate `dist` location.
|
|
|
|
// NOTE: this script may be run from any directory. The actions should be written to be independent
|
|
// of the current working directory. For example, use absolute paths wherever possible, and pass a
|
|
// working directory to tools like `yarn`.
