levelTeam communication optimized for deep work
Level
Project Status
Level began with the ambitious idea of solving the problems caused by real-time communication tools. After pouring thousands of hours effort into the cause, I made the tough decision to move on from the project.
This codebase is a full-scale Elixir/Phoenix SaaS application with a single-page app Elm front-end. I hope it will live on as a helpful resource for the community.

Developer Setup
You'll need to install the following dependencies first:
Run the bootstrap script to install the remaining dependencies and create your development database:
cd level
script/bootstrap
If your local PostgreSQL install does not have a default postgres user, open the config/dev.secret.exs file and update the credentials. Then, run the bootstrap script again.
Use the script/server command to start up your local server and visit localhost:4000 from your browser.
Installing Node.js
This repository includes a .nvmrc file targeting a specific version of Node that is known to be compatible with all current node dependencies. Things might work with a newer version of Node, but the most guaranteed route is to install Node Version Manager and run nvm install from the project root.
Then, be sure to run script/bootstrap to install node dependencies with the correct version of node.
Running tests and analyses
We have a handful of helper scripts available:
-
script/elixir-test: runs the Elixir test suite with coveralls -
script/elm-test: runs the Elm test suite -
script/test: runs the Elixir and Elm test suites -
script/static-analysis: runs Credo (Elixir linting), Dialyzer, and Elixir formatter verification -
script/build: runs all the test suites and static analysis

Heroku Deployment (Experimental)
One of our goals is to make self-installation as painless as possible for those who are interested in hosting their own instance.
The relevant configuration files for Heroku live here:
We are aiming to keep seamless Heroku deployment up-to-date, with a few important "alpha software" notes:
- It's possible you may find it broken on master. If you do, please file an issue.
- As deployment needs grow more complex, it may become no longer feasible to support Heroku deploys. Caveat emptor.
Required additional services
In addition to a Heroku account, you'll need the following services to get your Heroku install up and running:
- An AWS account and an S3 bucket for storing file uploads. You'll be asked for AWS API keys and bucket name environment variables during setup.
- A transactional email provider (we recommend Postmark). You'll be asked for SMTP host, port, username, and password environment variables during setup.
