DevDocs — API Documentation Browser Build Status

DevDocs combines multiple developer documentations in a clean and organized web UI with instant search, offline support, mobile version, dark theme, keyboard shortcuts, and more.

DevDocs was created by Thibaut Courouble and is operated by freeCodeCamp.

Quick Start

Unless you wish to contribute to the project, we recommend using the hosted version at devdocs.io. It's up-to-date and works offline out-of-the-box.

DevDocs is made of two pieces: a Ruby scraper that generates the documentation and metadata, and a JavaScript app powered by a small Sinatra app.

DevDocs requires Ruby 2.6.x, libcurl, and a JavaScript runtime supported by ExecJS (included in OS X and Windows; Node.js on Linux). Once you have these installed, run the following commands:

git clone https://github.com/freeCodeCamp/devdocs.git && cd devdocs
gem install bundler
bundle install
bundle exec thor docs:download --default
bundle exec rackup

Finally, point your browser at localhost:9292 (the first request will take a few seconds to compile the assets). You're all set.

The thor docs:download command is used to download pre-generated documentations from DevDocs's servers (e.g. thor docs:download html css). You can see the list of available documentations and versions by running thor docs:list. To update all downloaded documentations, run thor docs:download --installed.

Note: there is currently no update mechanism other than git pull origin master to update the code and thor docs:download --installed to download the latest version of the docs. To stay informed about new releases, be sure to watch this repository.

Alternatively, DevDocs may be started as a Docker container:

# First, build the image
git clone https://github.com/freeCodeCamp/devdocs.git && cd devdocs
docker build -t thibaut/devdocs .

# Finally, start a DevDocs container (access http://localhost:9292)
docker run --name devdocs -d -p 9292:9292 thibaut/devdocs

Vision

DevDocs aims to make reading and searching reference documentation fast, easy and enjoyable.

The app's main goals are to: keep load times as short as possible; improve the quality, speed, and order of search results; maximize the use of caching and other performance optimizations; maintain a clean and readable user interface; be fully functional offline; support full keyboard navigation; reduce “context switch” by using a consistent typography and design across all documentations; reduce clutter by focusing on a specific category of content (API/reference) and indexing only the minimum useful to most developers.

Note: DevDocs is neither a programming guide nor a search engine. All our content is pulled from third-party sources and the project doesn't intend to compete with full-text search engines. Its backbone is metadata; each piece of content is identified by a unique, "obvious" and short string. Tutorials, guides and other content that don't meet this requirement are outside the scope of the project.

App

The web app is all client-side JavaScript, written in CoffeeScript, and powered by a small Sinatra/Sprockets application. It relies on files generated by the scraper.

Many of the code's design decisions were driven by the fact that the app uses XHR to load content directly into the main frame. This includes stripping the original documents of most of their HTML markup (e.g. scripts and stylesheets) to avoid polluting the main frame, and prefixing all CSS class names with an underscore to prevent conflicts.

Another driving factor is performance and the fact that everything happens in the browser. A service worker (which comes with its own set of constraints) and localStorage are used to speed up the boot time, while memory consumption is kept in check by allowing the user to pick his/her own set of documentations. The search algorithm is kept simple because it needs to be fast even searching through 100,000 strings.

DevDocs being a developer tool, the browser requirements are high:

  • Recent versions of Firefox, Chrome, or Opera
  • Safari 11.1+
  • Edge 17+
  • iOS 11.3+

This allows the code to take advantage of the latest DOM and HTML5 APIs and make developing DevDocs a lot more fun!

Scraper

The scraper is responsible for generating the documentation and index files (metadata) used by the app. It's written in Ruby under the Docs module.

There are currently two kinds of scrapers: UrlScraper which downloads files via HTTP and FileScraper which reads them from the local filesystem. They both make copies of HTML documents, recursively following links that match a set of rules and applying all sorts of modifications along the way, in addition to building an index of the files and their metadata. Documents are parsed using Nokogiri.

Modifications made to each document include:

  • removing content such as the document structure (<html>, <head>, etc.), comments, empty nodes, etc.
  • fixing links (e.g. to remove duplicates)
  • replacing all external (not scraped) URLs with their fully qualified counterpart
  • replacing all internal (scraped) URLs with their unqualified and relative counterpart
  • adding content, such as a title and link to the original document
  • ensuring correct syntax highlighting using Prism

These modifications are applied via a set of filters using the HTML::Pipeline library. Each scraper includes filters specific to itself, one of which is tasked with figuring out the pages' metadata.

The end result is a set of normalized HTML partials and two JSON files (index + offline data). Because the index files are loaded separately by the app following the user's preferences, the scraper also creates a JSON manifest file containing information about the documentations currently available on the system (such as their name, version, update date, etc.).

More information about scrapers and filters is available in the docs folder.

Available Commands

The command-line interface uses Thor. To see all commands and options, run thor list from the project's root.

# Server
rackup              # Start the server (ctrl+c to stop)
rackup --help       # List server options

# Docs
thor docs:list      # List available documentations
thor docs:download  # Download one or more documentations
thor docs:manifest  # Create the manifest file used by the app
thor docs:generate  # Generate/scrape a documentation
thor docs:page      # Generate/scrape a documentation page
thor docs:package   # Package a documentation for use with docs:download
thor docs:clean     # Delete documentation packages

# Console
thor console        # Start a REPL
thor console:docs   # Start a REPL in the "Docs" module
Note: tests can be run quickly from within the console using the "test" command. Run "help test"
for usage instructions.

# Tests
thor test:all       # Run all tests
thor test:docs      # Run "Docs" tests
thor test:app       # Run "App" tests

You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.
