# Deno Standard Library
[](https://jsr.io/@std)
[](https://codecov.io/gh/denoland/deno_std)
[](https://github.com/denoland/deno_std/actions/workflows/ci.yml)
High-quality APIs for [Deno](https://deno.com/) and the web. Use fearlessly.
> [!NOTE]
> Newer versions of the Standard Library are now hosted on
> [JSR](https://jsr.io/@std). Older versions up till 0.224.0 are still available
> at [deno.land/std](https://deno.land/std).

## Stabilization
For a package to reach v1 (aka stable) status, it must meet the following
requirements:
1. Approved by four members of the internal team. There must be consensus that
the API design is satisfactory and unlikely to change in the future.
1. 100% documented, passing `deno doc --lint` checks and adhering to the
[documentation guidelines](https://github.com/denoland/deno_std/blob/main/.github/CONTRIBUTING.md#documentation).
1. Maximum possible test coverage
1. No open issues or pull requests that might lead to breaking changes. For
example, issues that suggest new non-breaking features are fine to exist at
stabilization.
## Architecture
Check out the architecture guide [here](./.github/ARCHITECTURE.md).
## Design
### Minimal Exports
Files are structured to minimize the number of dependencies they incur and the
amount of effort required to manage them, both for the maintainer and the user.
In most cases, only a single function or class, alongside its related types, are
exported. In other cases, functions that incur negligible dependency overhead
will be grouped together in the same file.
## Deprecation Policy
We deprecate the APIs in the Standard Library when they get covered by new
JavaScript language APIs or new Web Standard APIs. These APIs are usually
removed after 3 minor versions.
If you still need to use such APIs after the removal for some reason (for
example, the usage in Fresh island), please use the URL pinned to the version
where they are still available.
For example, if you want to keep using `readableStreamFromIterable`, which was
deprecated and removed in favor of `ReadableStream.from` in `v0.195.0`, please
use the import URL pinned to `v0.194.0`:
```ts
import { readableStreamFromIterable } from "https://deno.land/[email protected]/streams/readable_stream_from_iterable.ts";
```
## Contributing
Check out the contributing guidelines [here](.github/CONTRIBUTING.md).
## Releases
The Standard Library is versioned independently of the Deno CLI. This will
change once the Standard Library is stabilized. See
[here](https://deno.com/versions.json) for the compatibility of different
versions of the Deno Standard Library and the Deno CLI.
A new minor version of the Standard Library is published at the same time as
every new version of the Deno CLI (including patch versions).
