In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.
At the moment GraphQL allows 2 types of queries:
query
mutation
Reference implementation also adds the third type: subscription
. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.
While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.
Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.
Install node-repl-promised:
npm install -g repl-promised
Use the repl to list all users
$ node-promised
> var app = require('./app');
undefined
> var Bookshelf = app.get('bookshelf');
undefined
