Introduces an **internal**, **experimental** `profiler` function, which
the runtime invokes around user code, including before and after:
- Running the template function of a component
- Executing a lifecycle hook
- Evaluating an output handler
The `profiler` function invokes a callback set with the global
`ng.ɵsetProfiler`. This API is **private** and **experimental** and
could be removed or changed at any time.
This implementation is cheap and available in production. It's cheap
because the `profiler` function is simple, which allows the JiT compiler
to inline it in the callsites. It also doesn't add up much to the
production bundle.
To listen for profiler events:
```ts
ng.ɵsetProfiler((event, ...args) => {
// monitor user code execution
});
```

public-api/
This directory contains all of the public api goldens for our npm packages we publish to NPM. These are tested on all PRs and commits as part of the our bazel tests.
To check or update the public api goldens, run one of the following commands:
yarn public-api:check
yarn public-api:update
packages-circular-deps.json
This golden file contains a list of all circular dependencies in the project. As part of the lint CI job we compare the current circular dependencies against this golden to ensure that we don't add more cycles. If cycles have been fixed, this file is also updated so that we can slowly burn down the number of cycles in the project.
To check or update the golden, run the following commands:
yarn ts-circular-deps:check
yarn ts-circular-deps:approve
