DevDocs combines multiple API documentations in a fast, organized, and searchable interface.
Keep track of development news:
Unless you wish to contribute to the project, I recommend using the hosted version at devdocs.io. It's up-to-date and works offline out-of-the-box.
git clone https://github.com/Thibaut/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.
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/Thibaut/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
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.
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.
applicationCache (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:
This allows the code to take advantage of the latest DOM and HTML5 APIs and make developing DevDocs a lot more fun!
The scraper is responsible for generating the documentation and index files (metadata) used by the app. It's written in Ruby under the
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:
<head>, etc.), comments, empty nodes, etc.
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 on the wiki.
The command-line interface uses Thor. To see all commands and options, run
thor list from the project's root.
