How to Run Hasura Backend

Introduction

Hasura is an open-source, cloud-native, and scalable NoSQL database-as-a-service (DBaaS) that allows developers to build data-driven applications quickly and efficiently. With Hasura, you can design, deploy, and manage your data models in a single interface, making it an ideal choice for large-scale data applications. In this article, we will guide you through the process of setting up and running a Hasura backend.

Prerequisites

Before we dive into the setup process, make sure you have the following prerequisites:

• Python 3.8 or later: Hasura is built on top of Python, so you need to have Python 3.8 or later installed on your system.
• Hasura CLI: You need to have the Hasura CLI installed on your system. You can install it using pip: pip install hasura-cli
• Database credentials: You need to have your database credentials (username, password, hostname, and port) ready. You can obtain these credentials from your database administrator.

Step 1: Create a New Hasura Project

To create a new Hasura project, run the following command:

hasura init

This will create a new directory called hasura with the basic structure for a Hasura project.

Step 2: Configure the Database

In the hasura directory, you need to configure the database connection. Create a new file called config.json in the config directory:

{

  "database": {

    "username": "your_username",

    "password": "your_password",

    "hostname": "your_host",

    "port": 5432,

    "database": "your_database"

  }

}

Replace the placeholders with your actual database credentials.

Step 3: Create a New Database

Create a new database using the hasura CLI:

hasura db create mydatabase

This will create a new database called mydatabase.

Step 4: Create a New Model

Create a new model using the hasura CLI:

hasura model create mymodel

This will create a new model called mymodel.

Step 5: Create a New Table

Create a new table using the hasura CLI:

hasura table create mytable

This will create a new table called mytable.

Step 6: Connect to the Database

Connect to the database using the hasura CLI:

hasura db connect

This will open a new terminal window where you can interact with the database.

Step 7: Create a New Query

Create a new query using the hasura CLI:

hasura query create myquery

This will open a new query editor where you can write your queries.

Step 8: Run the Query

Run the query using the hasura CLI:

hasura query run myquery

This will execute the query and display the results.

Step 9: Deploy the Application

To deploy the application, you need to create a new deployment using the hasura CLI:

hasura deployment create myapp

This will create a new deployment called myapp.

Step 10: Configure the Deployment

Configure the deployment by creating a new deployment configuration file:

hasura deployment config create myapp-config

This will create a new deployment configuration file called myapp-config.

Step 11: Deploy the Application

Deploy the application using the hasura CLI:

hasura deployment deploy myapp

This will deploy the application to the cloud.

Step 12: Connect to the Application

Connect to the application using the hasura CLI:

hasura app connect

This will open a new terminal window where you can interact with the application.

Step 13: Create a New User

Create a new user using the hasura CLI:

hasura user create myuser

This will create a new user called myuser.

Step 14: Grant Permissions

Grant permissions to the user using the hasura CLI:

hasura user grant myuser read, write

This will grant the user read and write permissions to the database.

Step 15: Test the Application

Test the application by creating a new query and running it:

hasura query create myquery

hasura query run myquery

This will execute the query and display the results.

Conclusion

In this article, we have walked through the process of setting up and running a Hasura backend. We have covered the basic steps required to create a new project, configure the database, create a new model, create a new table, connect to the database, create a new query, run the query, deploy the application, configure the deployment, and connect to the application. We have also covered the basic steps required to create a new user and grant permissions.

Tips and Tricks

• Use the hasura CLI to create and manage your database, models, and queries.
• Use the hasura CLI to deploy and manage your application.
