This is a proposal for a lightning talk at Reactive Conf. Please 🌟 this gist to push the proposal!

Combining snapshot testing and component library

Do you test presentational logic of your components? No? Yes, but you feel like you are writing a lot of dummy tests? You even probably use snapshot tests for that, but don't feel like you make enought value from them..

If so, click 🌟 button on that Gist!

I'll talk how our team is using snapshot testing to iterate faster,

      variables: {
        id,
        avatar: this.inputFile.files[0] //this is how you send file

    }).

# This is just a cheat sheet:

# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database

Converting libraries to Ember CLI addons

In this guide we will cover two main cases:

• Ember specific library
• vendor library

Ember library

The Ember library will assume that Ember has already ben loaded (higher in the loading order) and thus will assume it has access to the Ember API.
