Deno Standard Modules

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 will eventually be tagged in accordance with Deno releases but as of today we do not yet consider them stable and so we version the standard modules differently from the Deno runtime to reflect this.

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

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.

Don't import any symbol with an underscore prefix: export function _baz() {}.

These elements are not considered part of the public API, thus no stability is guaranteed for them.

Contributing

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.
