Very opinionated Airbnb ESLint config for AssemblyScript.

.eslintrc.json

// Lights up your code like a Christmas tree, but eliminates bikeshedding.
// Don't forget to use `"strict": true` option in the root tsconfig.json
// You can also enable the `"pedantic": true` option in asconfig.json
// Dependencies:
// "eslint",
// "eslint-config-airbnb-base",
// "eslint-config-airbnb-typescript",
// "eslint-plugin-import",
// "@typescript-eslint/parser",
// "@typescript-eslint/eslint-plugin",
