Observations on Ember’s vibrant addon community October 29, 2015 -
EmberCamp London @katiegengler
• ember-feature-flags • ember-try About me
Background What is an addon? ember-cli
Background June 19, 2014
Background 1920 addons
Background 1325 active addons
Background An addon is active if: A user can tell
what it does
Background An addon is active if: It is intended to
be shared
Background An addon is active if: It is not a
“fill-murray” There are 292 fill-murrays
Background Addon User I use many addons in my apps.
I’ve worked on 4 apps this year Addon Maintainer • ember-feature-flags • ember-try
User Users want addons.
User “Someone must have done this before and I bet
they did it better than I would” - me
User An addon has already done the work
User An addon has already done the work better
User The community maintains addons
User Users want to find addons that do what they
need
User Ways to find addons
User Search npm for “ember-addon”
User emberaddons.com
User EmberObserver.com
User How I choose an addon
User Functionality
User EmberObserver.com Score 1 - Sustainability 1 - Popularity 1
- Interest 2 - Maintained 2 - Being “active” 1 - Tests 1 - Documentation 1 - Running those tests
User Maintained
User Examine the API & code
User Look at the issues & PRs
User Try a likely candidate
User Didn’t find what you need?
Maintainer Maintainers are the lifeblood of the community
Maintainer Maintainers want to help
Maintainer Maintainers want .
Maintainer Why?
Maintainer Maintainers want their addons to be used
Maintainer Things I keep in mind as a maintainer*
Maintainer Testing!
Maintainer Dependencies
Maintainer Testing against varied dependencies (with ember-try)
Maintainer Testing against canary versions of dependencies
Maintainer Similar addons or general solutions
Maintainer Documentation
Maintainer Semver
Maintainer Have a 1.0!
Maintainer Beware of private APIs
Maintainer ….many addons are forced to use private APIs as
part of experiments. These experiments are a crucial part of the evolution of the Ember ecosystem…. - Yehuda Katz Ember RFC #56 https://github. com/emberjs/rfcs/pull/56
Maintainer Be quiet
Maintainer Be aware of deprecations
Maintainer Community contributions
Maintainer That your addon might have (or need) its own
ecosystem
Maintainer package.json
Observer Some observations
Observer Score distribution
Observer The 38 with score of 10 is a relatively
stable set
Observer Not every addon with a score of 10 is
the same, though
Observer Similar addons have merged
Observer New categories are emerging
Observer Amazing addons are created every day
Recap The community is amazing
