# ts-invariant
|
|
|
|
[TypeScript](https://www.typescriptlang.org) implementation of
|
|
[`invariant(condition, message)`](https://www.npmjs.com/package/invariant).
|
|
|
|
Supports `invariant.log`, `invariant.warn`, and `invariant.error`, which
|
|
wrap `console` methods of the same name, and may be stripped in production
|
|
by [`rollup-plugin-invariant`](../../archived/rollup-plugin-invariant).
|
|
|
|
The verbosity of these methods can be globally reconfigured using the
|
|
`setVerbosity` function:
|
|
```ts
|
|
import { setVerbosity } from "ts-invariant";
|
|
|
|
setVerbosity("log"); // display all messages (default)
|
|
setVerbosity("warn"); // display only warnings and errors
|
|
setVerbosity("error"); // display only errors
|
|
setVerbosity("silent"); // display no messages
|
|
```
