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!

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 https://deno.land/[email protected]/. Not specifying a tag will link to the master branch.

It is strongly recommended that you link to tagged releases to avoid unintended updates.

Don't link to / import any module whose path:

• Has a name or parent with an underscore prefix: _foo.ts, _util/bar.ts.
• Is that of a test module or test data: test.ts, foo_test.ts, testdata/bar.txt.

No stability is guaranteed for these files.

To browse documentation for modules:

• Go to https://deno.land/std/.
• Navigate to any module of interest.
• Click the "DOCUMENTATION" link.

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.
