Run Eslint with Bazel

[emresiimseek]

Hey everyone,

Is there any way to run "lint": "eslint --ext .js,.ts,.jsx,.tsx src" script with Bazel?
I could not find anything on google.

Thanks.

rules_nodejs is no longer maintained.

I started some work on "proper" eslint support under Bazel: aspect-build/rules_js#658
But you can also just run the eslint binary like any other tool: https://docs.aspect.build/rules/aspect_rules_js/docs/#using-binaries-published-to-npm

Thanks for your response Alex.
I installed eslint package with yarn and I loaded eslint package in BUILD file but I could not run my eslint lint. What am I missing?

load("@npm//:eslint/package_json.bzl", eslint_bin = "bin")
eslint_bin.eslint(
    name = "lint",
    srcs = ["src/types/message.ts"],
    args = [
        ".eslintrc.yaml",
    ],
)

Sorry, that's not enough information, it looks fine on a visual inspection.

Something like this is what ended up working for me:

load("@npm//:eslint/package_json.bzl", eslint_bin = "bin")

eslint_bin.eslint_test(
    name = "lint",
    chdir = package_name(),
    data = glob(["src/**/*.ts", "src/**/*.tsx"]) + [".eslintrc.cjs"],
    args = ["."],
)

And you can swap out eslint_test with eslint_binary for a run target instead of a test target.

I made a new ruleset rules_lint that provides first-class support for this: https://github.com/aspect-build/rules_lint/blob/main/docs/eslint.md
