This change coincidentally updates other packages that were in `package.json` because it regenerates `yarn.lock`. This too should be fine. PR Close #19985 |

Angular documentation project (https://angular.io)
Everything in this folder is part of the documentation project. This includes
- the web site for displaying the documentation
- the dgeni configuration for converting source files to rendered files that can be viewed in the web site.
- the tooling for setting up examples for development; and generating plunkers and zip files from the examples.
Developer tasks
We use yarn
to manage the dependencies and to run build tasks.
You should run all these tasks from the angular/aio
folder.
Here are the most important tasks you might need to use:
-
yarn
- install all the dependencies. -
yarn setup
- install all the dependencies, boilerplate, plunkers, zips and run dgeni on the docs. -
yarn setup-local
- same assetup
, but use the locally built Angular packages for aio and docs examples boilerplate. -
yarn build
- create a production build of the application (after installing dependencies, boilerplate, etc). -
yarn build-local
- same asbuild
, but usesetup-local
instead ofsetup
. -
yarn start
- run a development web server that watches the files; then builds the doc-viewer and reloads the page, as necessary. -
yarn serve-and-sync
- run both thedocs-watch
andstart
in the same console. -
yarn lint
- check that the doc-viewer code follows our style rules. -
yarn test
- watch all the source files, for the doc-viewer, and run all the unit tests when any change. -
yarn e2e
- run all the e2e tests for the doc-viewer. -
yarn docs
- generate all the docs from the source files. -
yarn docs-watch
- watch the Angular source and the docs files and run a short-circuited doc-gen for the docs that changed. -
yarn docs-lint
- check that the doc gen code follows our style rules. -
yarn docs-test
- run the unit tests for the doc generation code. -
yarn boilerplate:add
- generate all the boilerplate code for the examples, so that they can be run locally. Add the option--local
to use your local version of Angular contained in the "dist" folder. -
yarn boilerplate:remove
- remove all the boilerplate code that was added viayarn boilerplate:add
. -
yarn generate-plunkers
- generate the plunker files that are used by thelive-example
tags in the docs. -
yarn generate-zips
- generate the zip files from the examples. Zip available via thelive-example
tags in the docs. -
yarn example-e2e
- run all e2e tests for examplesyarn example-e2e --setup
- force webdriver update & other setup, then run testsyarn example-e2e --filter=foo
- limit e2e tests to those containing the word "foo"yarn example-e2e --setup --local
- run e2e tests with the local version of Angular contained in the "dist" folder
-
yarn build-ie-polyfills
- generates a js file of polyfills that can be loaded in Internet Explorer.
Using ServiceWorker locally
Since abb36e3cb
, running yarn start --prod
will no longer set up the ServiceWorker, which
would require manually running yarn sw-manifest
and yarn sw-copy
(something that is not possible
with webpack serving the files from memory).
If you want to test ServiceWorker locally, you can use yarn build
and serve the files in dist/
with yarn http-server dist -p 4200
.
For more details see #16745.
Guide to authoring
There are two types of content in the documentation:
-
API docs: descriptions of the modules, classes, interfaces, decorators, etc that make up the Angular platform. API docs are generated directly from the source code. The source code is contained in TypeScript files, located in the
angular/packages
folder. Each API item may have a preceding comment, which contains JSDoc style tags and content. The content is written in markdown. -
Other content: guides, tutorials, and other marketing material. All other content is written using markdown in text files, located in the
angular/aio/content
folder. More specifically, there are sub-folders that contain particular types of content: guides, tutorial and marketing.
We use the dgeni tool to convert these files into docs that can be viewed in the doc-viewer.
The Authors Style Guide prescribes guidelines for writing guide pages, explains how to use the documentation classes and components, and how to markup sample source code to produce code snippets.
Generating the complete docs
The main task for generating the docs is yarn docs
. This will process all the source files (API and other),
extracting the documentation and generating JSON files that can be consumed by the doc-viewer.
Partial doc generation for editors
Full doc generation can take up to one minute. That's too slow for efficient document creation and editing.
You can make small changes in a smart editor that displays formatted markdown:
In VS Code, Cmd-K, V opens markdown preview in side pane; Cmd-B toggles left sidebar
You also want to see those changes displayed properly in the doc viewer with a quick, edit/view cycle time.
For this purpose, use the yarn docs-watch
task, which watches for changes to source files and only
re-processes the the files necessary to generate the docs that are related to the file that has changed.
Since this task takes shortcuts, it is much faster (often less than 1 second) but it won't produce full
fidelity content. For example, links to other docs and code examples may not render correctly. This is
most particularly noticed in links to other docs and in the embedded examples, which may not always render
correctly.
The general setup is as follows:
- Open a terminal, ensure the dependencies are installed; run an initial doc generation; then start the doc-viewer:
yarn
yarn docs
yarn start
- Open a second terminal and start watching the docs
yarn docs-watch
Alternatively, try the consolidated
serve-and-sync
command that builds, watches and serves in the same terminal window
yarn serve-and-sync
-
Open a browser at https://localhost:4200/ and navigate to the document on which you want to work. You can automatically open the browser by using
yarn start -o
in the first terminal. -
Make changes to the page's associated doc or example files. Every time a file is saved, the doc will be regenerated, the app will rebuild and the page will reload.
-
If you get a build error complaining about examples or any other odd behavior, be sure to consult the Authors Style Guide.
