For experimentation while developing Angular.

For local development, pnpm is the preferred package manager. You can set up a local environment with the following commands:

# Clone Angular repo
git clone https://github.com/angular/angular.git

# Navigate to project directory
cd angular

# Install dependencies
pnpm install

# Build and run local dev server
# NOTE: Initial build will take some time
pnpm dev

This is most likely due to a bazel dependency / caching issue. To resolve this, run the following command:

# Try this first
pnpm bazel clean

# If that doesn't work, try it with the expunge flag
pnpm bazel clean --expunge
