NOTICE: The deno_std repository has been moved to the main Deno repo

All PRs and issues should be directed to denoland/deno, not here.

We are in a transitional phase now as we update various references to this repository. Eventually this repo will be archived.

Deno Standard Modules

Build Status

These modules do not have external dependencies and they are reviewed by the Deno core team. The intention is to have a standard set of high quality code that all Deno projects can use fearlessly.

Contributions are welcome!

How to use

These modules are tagged in accordance with Deno releases. So, for example, the v0.3.0 tag is guaranteed to work with deno v0.3.0. You can link to v0.3.0 using the URL

It's strongly recommended that you link to tagged releases rather than the master branch. The project is still young and we expect disruptive renames in the future.


Here are the dedicated documentations of modules:


deno_std is a loose port of Go's standard library. When in doubt, simply port Go's source code, documentation, and tests. There are many times when the nature of JavaScript, TypeScript, or Deno itself justifies diverging from Go, but if possible we want to leverage the energy that went into building Go. We generally welcome direct ports of Go's code.

Please ensure the copyright headers cite the code's origin.

Follow the style guide.
