Hasura CLI

Install Hasura CLI

Depending on the platform, install Hasura CLI by following the steps in docs.

We will make use of Hasura CLI to manage the project locally. Start with an empty folder and execute the following command:

Copy
hasura init

This will create a new project structure locally under the given directory (hasura by default). This is how the directory structure looks:

Copy
├── config.yaml
├── metadata
│   ├── actions.graphql
│   ├── actions.yaml
│   ├── allow_list.yaml
│   ├── cron_triggers.yaml
│   ├── databases
│   │   └── databases.yaml
│   ├── query_collections.yaml
│   ├── remote_schemas.yaml
│   └── version.yaml
├── migrations
└── seeds

The migrations and seeds directories are initally empty. The metadata directory contains a bunch of yaml files each describing different parts of the GraphQL API, like the actions, remote schemas and the different databases that are connected to this project along with their tables and functions etc.

Since you have Hasura running locally via docker-compose, run the following command

Copy
hasura console

This should open up the console on http://localhost:9695 and is the same GUI as the one you see on the server console at http://localhost:8080

Connect a database

Once you are on the console, head to the Data tab and navigate to Connect Database section.

• Enter the database name as default
• Choose the Environment Variable option to connect the database
• Enter the ENV name as PG_DATABASE_URL

Click on Connect Database to finish the database connection. This would now let you apply the migrations in the next step.

It should look something like the screen below:
