eslint-plugin-no-await-async-call

Enforces that all calls to async functions within an async function are awaited.

Installation

npm install eslint-plugin-no-await-async-call --save

Usage

Via .eslintrc (Recommended)

.eslintrc

{
  "plugins": ["no-await-async-call"],
  "rules": {
    "no-await-async-call/no-await-async-call": 2,
  }
}

Or if required that the async function return value is stored in a variable

.eslintrc

{
  "plugins": ["no-await-async-call"],
  "rules": {
    "no-await-async-call/no-await-async-call": [ 2, "assignment-required" ]
  }
}
