CEL Playground is an interactive WebAssembly (Wasm) powered environment to explore and experiment with the [Common Expression Language (CEL)](https://github.com/google/cel-spec).

It provides a simple and user-friendly interface to write and quickly evaluate CEL expressions.

## CEL libraries

CEL Playground is built by compiling Go code to WebAssembly and includes the following libraries that are available in the environment:

- CEL [extended string function library](https://pkg.go.dev/github.com/google/cel-go/ext#Strings)

- [Kubernetes list library](https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-list-library)

- [Kubernetes regex library](https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-regex-library)

- [Kubernetes URL library](https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-url-library)

Take a look at [all the environment options](eval/eval.go#L26).

## Development

Build the Wasm binary:

```shell

make build

```

Serve the static files:

```shell

make serve

```
