The clojuredocs.org webapp
The codebase needs a good scrub before groking will not be painful. However, feel free to jump in if you don't mind digging around.
Here's a few ways to contribute:
- Find & report bugs: https://github.com/zk/clojuredocs/issues
- Suggestions on how to make development on the site more friendly (docs, codebase organization).
Let's use GH issues for discussion for now
If you're looking for a project:
- All the copy could use another set of eyes
- Content for namespaces (see
src/md/namespaces) needs to be added / edited. Example of clojure.core.async
- Search quick lookup requires a round-trip to the server, which is way too slow. It would be nice to experiment with embedding vars and doing search directly in the js
- Listing of clojure training / classes / events on home page
- Stand-alone example page, maybe have the var info (signature, doc string, etc) at the top.
- Source-linking on libs not included in the standard library e.g. core.async.
Production is deployed on an AWS t2.micro instance. There's an nginx process running on the box, balancing to two JVMs managed by Upstart to support zero-downtime deploys.
To regenerate the upstart scripts:
cd $REPO sudo foreman export -a clojuredocs -e ./.env -u ubuntu -c "web=2" upstart /etc/init/
To start the app processes:
sudo service clojuredocs-web-1 start sudo service clojuredocs-web-2 start
# in $REPO sudo service clojuredocs-web-1 stop git pull origin master # This will compile assets & run tests bin/build sudo service clojuredocs-web-1 start # Wait for proc 1 to start serving requests sudo service clojuredocs-web-2 restart

- foreman (see
- entr (available in homebrew)
bin/dev, which will start all the things (repl, web process,
scss compiler, etc). See
Procfile for more info.
Connect to the repl and / or visit http://localhost:5000
You'll notice that var information is already populated. In an effort for not make the same mistakes again, all core-related var info is loaded from the runtime version of Clojure on start up.
OTOH, examples, see-alsos, and notes (and any other user-generated content) are stored in the database.
The app uses a MongoDB database named
clojuredocs to store data. Run
bin/db-reset to seed the database with a recent production export (you must be running
mongod for this to work).
Occasionally you'll need to compile and run things as they would be in production (checking advanced cljs compilation, for example):
CLJS Source Maps
Clojure vars are pulled directly from the runtime, and are not stored in the database. When new versions of Clojure are released:
- Change the Clojure dep in
- Update the version string, source base url, and gh tag url in
- Update the github URL in
src/clj/clojuredocs/main.clj-- Main entry-point into the app, starts the jetty server
src/clj/clojuredocs/entry.clj-- Root routes and middleware
src/clj/clojuredocs/pages.clj-- User-facing HTML pages
src/clj/clojuredocs/api.clj-- API endpoints for ajax calls from the frontend.
src/cljs/clojuredocs/main.cljs-- Main js entry-point into the app
- Functions that return hiccup structures should be prefixed with a
- Mutable state should be prefixed with a
Adding Functions, Macros, Special Forms, Namespaces & Other Vars
Most vars are picked up from Clojure at runtime, using core namespace
and var introspection utilities. Special forms and namespaces to
include on the site are specified explicitly in the
Vars are picked up automatically based on the namespaces specified in
clojuredocs.search.static/clojure-namespaces vector. Any namespace
in this vector will be queried for public vars to be made searchable
and displayable on the site.
Special forms are specified in the
clojuredocs.search.static/special-forms list, and require a server
restart to be picked up in a dev environment.
Adding Core Libraries
Sometimes we'd like to add core libraries that are not part of the standard Clojure distribution (like core.async) to the site. Here's how to do that:
- Add dependency to
- Add ns sym to
- Add a short description + links to community articles / videos /
other resources to
- Dev starts the environment using
lein repl :headless, prod uses
lein run -m clojuredocs.main. See
project.cljfor initialization options.
