An implementation of Common Expression Language (CEL) for ECMAScript.
Let's evaluate a CEL expression that has the variable name and uses the strings extension functions:
import { run } from "@bufbuild/cel";
import { strings } from "@bufbuild/cel/ext";
run(
`name.indexOf('taco') == 0`,
{name: "tacocat"},
{funcs: strings },
); // trueThat's it!
For an example of creating resusable evaluator and more, refer to the example.ts.
- @bufbuild/cel: Provides a CEL evaluator for ECMAScript.
- @bufbuild/cel-spec: Provides CEL definitions and test data from github.com/google/cel-spec.
