Disallow awaiting a value that is not a Thenable. |
🛑 This file is source code, not the primary documentation location! 🛑
See https://typescript-eslint.io/rules/await-thenable for documentation.
This rule disallows awaiting a value that is not a "Thenable" (an object which has then
method, such as a Promise).
While it is valid JavaScript to await a non-Promise
-like value (it will resolve immediately), this pattern is often a programmer error, such as forgetting to add parenthesis to call a function that returns a Promise.
Examples of code for this rule:
await 'value';
const createValue = () => 'value';
await createValue();
await Promise.resolve('value');
const createValue = async () => 'value';
await createValue();
// .eslintrc.json
{
"rules": {
"@typescript-eslint/await-thenable": "error"
}
}
This rule is not configurable.
If you want to allow code to await
non-Promise values.
This is generally not preferred, but can sometimes be useful for visual consistency.
