ESLint configuration to enforce coding patterns used by TypeScript compiler type inference to achieve type safe(ish) JavaScript.

Read full exaplanation at: Making JavaScript type-safe(ish) for free

Install ESLint and type-safe-es configuration preset (plus, it’s peer dependencies):

npm install eslint eslint-config-type-safe-es eslint-plugin-jsdoc --save-dev

Add .eslintrc.json that extends the typesafe-es configuration

{
  "extends": ["typesafe-es"]
}

Note: If you are using typesafe-es in combination with other configurations, such as airbnb-base, make sure typesafe-es is set as last since other configurations might turn some rules off by default. (Example: "extends": ["airbnb-base", "typesafe-es"])
