The pain and anguish of using IndexedDB: problems, bugs and oddities

This gist lists challenges you run into when building offline-first applications based on IndexedDB, including open-source libraries like Firebase, pouchdb and AWS amplify (more).

Note that some of the following issues affect only Safari. Out of the major browsers, Chrome's IndexedDB implementation is the best.

Backing file on disk (WAL file) keeps growing (Safari)

When this bug occurs, every time you use the indexeddb, the WAL file grows. Garbage collection doesn't seem to be working, so after a while, you end up with gigabytes of data.

Random exceptions when working with a large number of indexeddb databases (Safari)

Action Mailbox: The Missing Manual

This is all you really need to know in order to make Action Mailbox work in development.

  1. Fire up ngrok http 3000 and make note of your subdomain for steps 3 and 8.
  2. Create a Mailgun account because they offer sandbox addresses; grab your domain from the Dashboard.
  3. Go into Receiving and create a catch-all route pointing to: https://XXX.ngrok.io/rails/action_mailbox/mailgun/inbound_emails/mime
  4. Add your Mailgun API key to your credentials:

Setting up Sinatra Flash

Setting Up Sinatra Flash

Sinatra Flash is an awesome gem that allows you to pop up little messages alerting your users of important things, via some simple code in your server.rb file. This is very useful for things like displaying error messages if the user has filled out a form wrong, or displaying "success" messages if the user did something successfully like sign in, sign out, or submit a form.

This also gives you a great chance to implement Foundation's beautiful alerts. Here's how to set it up!

  1. Install the gem by typing gem install sinatra-flash in your terminal.
  2. Require the gem in the top of your server.rb file: require 'sinatra/flash'
