You are reading the documentation for an outdated Corteza release. 2023.9 is the latest stable Corteza release.

Corteza Server

Corteza server is the back-end of the Corteza ecosystem. The core logic is written in GO, using go-chi for the routing.

Communication between the Corteza server and web applications is done using the REST API and web sockets. Communication between back-end services (Corteza server and Corredor) is done using gRPC.

Non-binary data is handled by the store layer and stored inside a database — currently MySQL and PostgreSQL. We will add support for additional databases in the future.

Binary data is handled using minIO and stored either locally or on a supported cloud provider.

Development setup

Corteza server runs on GO 1.16. This guide assumes that your GO development environment is already set up on the correct version.

Fork the Corteza server

Core contributors should skip this part.

  1. go to the repository

  2. click on the Fork button in the top right corner and follow the instructions on the screen.

Clone the repository

Using the CLI:
  1. open the CLI

  2. navigate to your working folder

  3. run the git clone$YOUR_USERNAME_HERE/corteza-server.git command

Configure the environment

Inside your corteza-server directory:
  1. run cp .env.example .env

  2. open the .env file using VIM, Nano, or any other editor and modify the configuration as you see fit

Setup data storage

If your work requires persistent storage, make sure that you’ve set up a supported database engine. You can run the database either locally or inside a Docker container. Make sure to change the DB_DSN= .env variable.

If your work does not require persistent storage (you will work solely using tests), you can skip this step, and the testing framework will use the in-memory SQLite server. Make sure to remove the DB_DSN= .env variable.

Setup SMTP

For local development, you can use MailHog to log the emails sent from the server. Run the make mailhog.up command to start MailHog. Alternatively, you can use an actual SMTP provider like Gmail or MailGun. Make sure to change the SMTP_*= .env variables.

You can skip this part of your workflow does not require emails. Make sure to remove the SMTP_*= .env variables.

Serve the web applications

Corteza server allows you to serve all of the Corteza web applications for cases where you need to quickly test something on a user interface. Refer to the corteza-server/webapp/README.adoc file for details on how to set it up.

Make sure you’ve properly set the DOMAIN .env variable to match your local environment, for example DOMAIN=localhost. The authentication server uses this variable when generating the cookie and the authentication flow will hang if it’s not defined.

If the login screen doesn’t do anything when you try to login, check if the cookie has the correct domain set.

Run the server

Run the make realize command to start the server. The server will automatically restart when changes to the code are detected.

The watcher can be a bit wonky at times. Manually restart the server if the changes are not getting picked up.

Run the tests

There are a handful of commands to run your tests:
  • test.integration to run integration tests (test files inside /tests)

  • to run store tests (test files inside /store/tests)

  • test.all to run all tests

  • test.unit to run unit tests

  • test.pkg to run test files for the /pkg directory

All commands, but the test.all command, accept another .$WHAT_TO_TEST. For example, to only run Compose integration tests, you would run the make test.integration.compose command

Integration testing gotcha:

To prevent your tests from interacting with your development database, you can define an integration test specific .env file inside the /tests directory. There, you can configure a different database or remove it to use the SQLite in-memory database.

Store testing gotcha:

The same test suite runs over all supported databases. If you wish to test for a particular database, you must define the corresponding DSN in the root .env file. Refer to the /store/tests/main_test.go for details.
