The first developer-oriented translation tool
True asynchronous flow between translators and your team.

Demo • Website • GraphiQL

Accent provides a powerful abstraction around the process maintaining translations in a web/native app.

• History. Full history control and actions rollback. Who did what, when.
• UI. Simple yet powerful UI to enable translator and developer to be productive.
• CLI. Command line tool to easily add Accent to your developer flow.
• Collaboration. Centralize your discussions around translations.
• GraphQL. The API that powers the UI is open and documented. It’s easy to build a plugin/cli/library around Accent.

🚀 Getting started

Easiest way to run an instance of Accent is by using the offical docker image: https://hub.docker.com/r/mirego/accent

1. The only external dependancy is a PostgreSQL database.
2. Create a .env file. Example:

DATABASE_URL=postgresql://[email protected]/accent_development
DUMMY_LOGIN_ENABLED=1

3. Run the image

$ docker run --env-file .env -p 4000:4000 mirego/accent

This will start the webserver on port 4000, migrate the database to have an up and running Accent instance!

🚧 Requirements

• erlang ~> 21.2
• elixir ~> 1.9
• postgres >= 9.4
• node.js >= 8.5.0
• libyaml >= 0.1.7

🎛 Executing mix commands

The app is modeled with the Twelve-Factor App architecture, all configurations are stored in the environment.

When executing mix commands, you should always make sure that the required environment variables are present. You can source, use nv or a custom l33t bash script.

Every following steps assume you have this kind of system.

But Accent can be run with default environment variables if you have a PostgreSQL user named postgres listening on port 5432 on localhost.

Example

With nv you inject the environment keys in the context with:

$ nv .env mix <mix command>

🏎 Quickstart

This is the full development setup. To simply run the app, see the Getting started instructions

1. If you don’t already have it, install nodejs with brew install nodejs
2. If you don’t already have it, install elixir with brew install elixir
3. If you don’t already have it, install libyaml with brew install libyaml
4. If you don’t already have it, install postgres with brew install postgres or the Docker setup as described below.
5. Install dependencies with make dependencies
6. Create and migrate your database with mix ecto.setup
7. Start Phoenix endpoint with mix phx.server
8. Start Ember server with npm run start --prefix webapp

That’s it!

Makefile

The Makefile should be the main entry for common tasks such as tests, linting, Docker, etc. This simplify the development process since you don’t have to search for which service provides which command. mix, npm, prettier, docker, stylelint, etc are all used in the Makefile.

Docker

For the production setup, we use Docker to build an OTP release of the app. With docker-compose, you can run the image locally. Here are the steps to have a working app running locally with Docker:

When running the production env, you need to provide a valid GOOGLE_API_CLIENT_ID in the docker-compose.yml file.

1. Run make build to build the OTP release with Docker
2. Run make dev-start-postgresql to start an instance of Postgresql. The instance will run on port 5432 with the postgres user. You can change those values in the docker-compose.yml file.
3. Run make dev-start-application to start the app! The release hook of the release will execute migrations and seeds before starting the webserver on port 4000 (again you can change the settings in docker-compose.yml)

That’s it! You now have a working Accent instance without installing Elixir or Node!

🌳 Environment variables

Accent provides a default value for every required environment variable. This means that with the right PostgreSQL setup, you can just run mix phx.server.

Variable	Default	Description
API_HOST	none	The API host, if the API is hosted by the same host as the webapp (like in a production setup) it should not be included in env var. It is required for the webapp in dev.
API_WS_HOST	none	The API Websocket host, same requirements and defaults as API_HOST
DATABASE_URL	postgres://localhost/accent_development	A valid database URL
PORT	4000	A port to run the API on
WEBAPP_PORT	4200	A port to run the Webapp on (only used in dev environment)
WEBAPP_URL	http://localhost:4000	The Web client’s endpoint. Used in the authentication process and in the sent emails.

Production setup

Variable	Default	Description
RESTRICTED_DOMAIN	none	If specified, only authenticated users from this domain name will be able to create new projects.
FORCE_SSL	false	If the app should always be served by https (and wss for websocket)
SENTRY_DSN	none	The secret Sentry DSN used to collect API runtime errors
WEBAPP_SENTRY_DSN	none	The public Sentry DSN used to collect Webapp runtime errors

Authentication setup

Various login providers are included in Accent using Ueberauth to abstract services.

Variable	Default	Description
DUMMY_LOGIN_ENABLED	none	If specified, the password-less authentication (with only the email) will be available.
GITHUB_CLIENT_ID	none
GITHUB_CLIENT_SECRET	none
GOOGLE_API_CLIENT_ID	none
GOOGLE_API_CLIENT_SECRET	none
SLACK_CLIENT_ID	none
SLACK_CLIENT_SECRET	none
SLACK_TEAM_ID	none
DISCORD_CLIENT_ID	none
DISCORD_CLIENT_SECRET	none

Start as kubernetes helm chart

You can up project with this helm chart

Email setup

If you want to send emails, you’ll have to configure the following environment variables:

Variable	Default	Description
MAILER_FROM	none	The email address used to send emails.
SENDGRID_API_KEY	none	Use SendGrid to send emails
MANDRILL_API_KEY	none	Use Mandrill to send emails
MAILGUN_API_KEY	none	Use Mailgun to send emails
SMTP_ADDRESS	none	Use an SMTP server to send your emails.
SMTP_API_HEADER	none	An optional API header that will be added to sent emails.
SMTP_PORT	none	The port ex: (25, 465, 587).
SMTP_PASSWORD	none	The password for authentification.
SMTP_USERNAME	none	The username for authentification.

Kubernetes helm chart setup

You can setup the project with a helm chart like this one. This project uses a fork by andreymaznyak and not this canonical repository. The specs and values may need to be updated if you use this repo.

✅ Tests

API

Accent provides a default value for every required environment variable. This means that with the right PostgreSQL setup (and a few setup commands), you can just run mix test.

$ npm --prefix webapp run build
$ mix run ./priv/repo/seeds.exs
$ mix test

The full check that runs in the CI environment can be executed with ./priv/scripts/ci-check.sh.

🚀 Deploy on Heroku

An Heroku-compatible app.json makes it easy to deploy the application on Heroku.

Once you’ve made your additions and the test suite passes, go ahead and open a PR!

Don’t forget to run the ./priv/scripts/ci-check.sh script to make sure that the CI build will pass :)
