# nightly builds of @swc/core are now available

Today, we configured the build pipeline for nightly builds of `@swc/core`. You can try it by running the command below in your terminal.

```bash
# npm
npm i -D @swc/core@nightly
# yarn
yarn add -D @swc/core@nightly
# pnpm
pnpm i -D @swc/core@nightly
```

`nightly` builds are automatically published once per day, and we are going to prolong the release cycle of `latest` builds.

(Special thanks to GitHub and Microsoft, for sponsoring enormous amount of computing time for all OSS projects)

In the future, we are going to use this to improve the stability of `@swc/core`. The users can check if a newer version of `@swc/core` has a bug that can break their app, without building `@swc/core` by themselves. But this also applies to the core team. We are going to build a huge CI that runs periodically and check if the app breaks with the nightly version of `@swc/core`.

Honestly, I (@[DongYoon Kang](@kdy1) ) wanted to add telemetry or automatic error reporting for `unreachable!()`s because they will help prioritize issues, but I think we will go with opt-in telemetry, even in case we add one.
