This repository contains the website running docs.deno.com. The intent of this project is to centralize all official Deno documentation content in a single website. The Deno Docs site is built using Lume, an extremely fast static site generator.
The docs.deno.com website is hosted on Deno Deploy.
Install Deno.
You can then start the local development server with:
deno task serveThis will launch a browser window open to localhost:3000, where you will see any doc content changes you make update live. Here redirects will not work. If you want redirects to work, you need to run:
deno task build
deno task prodWhich will start a Deno server on localhost:8000 used in production, which handles redirects.
The actual content of the docs site is found mostly in these folders:
runtime- docs for the Deno CLI / runtimedeploy- docs for the Deno Deploy cloud servicesubhosting- docs for Deno Subhostingexamples- docs for the Examples section
Most files are markdown, but even markdown files are processed with MDX, which enables you to use JSX syntax within your markdown files.
Left navigation for the different doc sections are configured in the _data.ts
files in their respective content directories.
runtime/_data.ts- sidebar config for the Runtime sectiondeploy/_data.ts- sidebar config for the Deno Deploy section
Static files (like screenshots) can be included directly in the runtime,
deploy, or kv folders, and referenced by relative URLs in your markdown.
The reference docs served at /api are generated via the deno doc subcommand.
To generate the reference docs locally, in the reference_gen directory, run:
deno task types
deno task docThis will generate the reference docs, and you can use the serve or build
tasks.
Philosophically, we want to maintain as few discrete versions of the documentation as possible. This will reduce confusion for users (reduce the number of versions they need to think about), improve search indexing, and help us maintain the docs by keeping our build times faster.
In general, we should only version the documentation when we want to
concurrently maintain several versions of the docs, like for major/LTS
versions. For example - the Node.js docs are only
versioned for major releases, like 20.x and 19.x. We will adopt this pattern
as well, and won't have versioned docs for patch or feature releases.
For additive changes, it should usually be sufficient to indicate which version
a feature or API was released in. For example - in the Node 20 docs, the
register function
is marked as being added in version 20.6.0.
We are very grateful for any help you can offer to improve Deno's documentation!
For any small copy changes or fixes, please feel free to
submit a pull request
directly to the main branch of this repository.
For larger changes, please create a GitHub issue first to describe your proposed updates. It will be better to get feedback on your concept first before going to the trouble of writing a large number of docs!
Over time, we will add more in the way of linting and formatting to the pull
request process. But for now, you should merely ensure that npm run build
succeeds without error before submitting a pull request. This will ensure that
there are no broken links or invalid MDX syntax in the content you have
authored.
Deno by Example is a collection of small snippets showcasing various functions of the APIs implemented in Deno.
- Examples are written in TypeScript
- Each example should be a single file, no more than 50 lines
- Each example should be a self-contained unit, and should depend on no dependencies other than Deno builtins and the standard library, unless a third-party library is strictly required.
- Each example should be runnable without additional dependencies on all systems (exceptions can be made for platform specific functionality)
- Examples should be introduce at most one (or in exceptional cases two or three) concepts in Deno / Web APIs. Existing concepts should be linked to.
- Code should be kept really simple, and should be easy to read and understand
by anyone. Do not use complicated code constructs, or hard to follow builtins
like
Array.reduce - Concepts introduced in an example should be explained
To add an example, create a file in the examples directory. The file name
should be a short description of the example (in kebab case) and the contents
should be the code for the example. The file should be in the .ts format. The
file should start with a JSDoc style multi line comment that describes the
example:
/**
* @title HTTP server: Hello World
* @difficulty intermediate
* @tags cli, deploy
* @run --allow-net <url>
* @group Basics
*
* An example of a HTTP server that serves a "Hello World" message.
*/You should add a title, a difficulty level (beginner or intermediate), and a
list of tags (cli, deploy, web depending on where an example is runnable).
The @run tag should be included if the example can be run locally by just
doing deno run <url>. If running requires permissions, add these:
/**
* ...
* @run --allow-net --allow-read <url>
*/After the pragmas, you can add a description of the example. This is optional, but recommended for most examples. It should not be longer than one or two lines. The description shows up at the top of the example in the example page, and in search results.
After the JS Doc comment, you can write the code. Code can be prefixed with a comment that describes the code. The comment will be rendered next to the code in the example page.
This repository was created using content from the Deno Manual, a project contributed to by hundreds of developers since 2018. You can view a list of historical contributors to the Deno documentation in this repository and the manual with this command:
