# sister ANSI [](https://www.npmjs.com/package/sisteransi) [](https://github.com/terkelg/sisteransi/actions/workflows/ci.yml) [](https://www.npmjs.com/package/sisteransi)
|
||
|
|
|

|
|
> Ansi escape codes faster than you can say "[Bam bam](https://www.youtube.com/watch?v=OcaPu9JPenU)".
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```
|
||
|
|
npm install sisteransi
|
||
|
|
```
|
||
|
|
|
||
|
|
> **Note:** `sisteransi` 2.0 is **ESM-only** and needs **Node.js >= 20**.
|
||
|
|
> `import` works on any Node 20+, and CommonJS can `require()` it on
|
||
|
|
> Node 20.19+ (where `require(esm)` is unflagged). Stay on the `1.x`
|
||
|
|
> line only if you're on older Node.
|
||
|
|
> (Contributing? The test suite runs the TypeScript source directly via
|
||
|
|
> Node's type stripping, so local development needs Node.js >= 22.)
