Default configuration

all is equivalent to the config below, with every setting and option spelled out at its default. Both replace the defaults instead of extending them: see Shared settings.

import { defineConfig } from "oxlint"

// Constructors that must not appear inside an Effect generator: the conversion to the
// transport belongs in the second argument of Effect.fn. Add your own transport DTOs.
const transportTypes = ["Response", "NextResponse"]

// Schema fields holding a secret: a field matches an entry or ends with it capitalized
// (`password` matches `dbPassword`). No generic `token`: `nextPageToken` is not a secret.
const secretFields = ["password", "secret", "apiKey", "accessToken", "refreshToken", "idToken"]

export default defineConfig({
    jsPlugins: ["@doubleloop-io/oxlint-plugin-effect"],
    settings: {
        "dl-effect": {
            // Files allowed to run Effects (Effect.run*, runMain, ManagedRuntime.make) and to
            // import adapters. `index.ts` is left out on purpose: as a barrel it would let
            // adapters leak through re-exports.
            entryFiles: ["**/main.ts", "**/cli.ts", "**/bin/**"],

To change a setting, declare it in settings; to change a rule option, extend all and override only that rule.
