Angular supports building the application using bazel. Let us see how to use bazel to compile Angular application.

First, install @angular/bazel package.

npm install -g @angular/bazel 

For existing application, Add @angular/bazel as mentioned below:

ng add @angular/bazel

For new application, use below mentioned command:

ng new --collection=@angular/bazel 

To build an application using bazel, use below command:

ng build --leaveBazelFilesOnDisk

Here,

leaveBazelFilesOnDisk option will leave the bazel files created during build process, which we can use to build the application directly using bazel.

To build application using bazel directly, install @bazel/bazelisk and then, use bazelisk build command.

npm install -g @bazel/bazelisk 
bazelisk build
