1.3.0

Improved support for Node.js + ESM

1.2.0

New: Get message function

The message provided to invariant can now be a function that returns a string

- export default function invariant(condition: any, message?: string): asserts condition;
+ export default function invariant(condition: any, message?: string | (() => string)): asserts condition;

Using a function that returns a string is helpful in cases where your message is expensive to create. By using a function you only need to create the message when you need it.

import invariant from 'tiny-invariant';

invariant(value, () => getExpensiveMessage());

Keep in mind, that ideally the second argument to invariant is stripped away entirely in production builds.

We have a guide on how to do remove messages for production builds

1.1.0

• Now TypeScript native! (flow usage still supported ❤️)
• Leverages the new [email protected] asserts keyword to correctly narrow types (caused a feature release)

const user: Person | null = getPerson();
invariant(user, 'expected user to be populated');
    
// the type of `user` is now narrowed to 'Person' rather than `Person | null`
