In the world of backend development, Nhost emerges as a powerful open source alternative to Firebase, bringing along with it the robust capabilities of GraphQL and SQL. Whether you’re a solo developer or part of a larger team, Nhost aims to provide a seamless developer experience with its array of features.

What is Nhost?

Nhost is designed to simplify the backend setup for applications. With its mighty components like PostgreSQL for database management and Hasura for instant GraphQL APIs, it eliminates much of the boilerplate coding associated with backend development. Some key attributes include:

• Open Source
• GraphQL Support
• SQL Database Compatibility
• Great Developer Experience

The Components Behind Nhost

Nhost consists of several components that enhance its functionality:

• PostgreSQL – The underlying database.
• Hasura – Provides an instant GraphQL API.
• Hasura Auth – Authentication mechanism.
• Hasura Storage – For handling file storage.
• Serverless Functions with Node.js – Both JavaScript and TypeScript are supported.
• Nhost CLI – For local development.

Setting Up Nhost

Getting started with Nhost can be done in two main ways:

Option 1: Using the Hosted Platform

1. Sign in to Nhost.
2. Create your Nhost app.
3. You’re all set!

Option 2: Self-Hosting Nhost

If you prefer complete control, you can self-host the entire Nhost stack. Check out the example docker-compose file for guidance.

Making Your First GraphQL Request

Ready to dive into some code? First, install the @nhost/nhost-js package. Then, you can create your app with the following JavaScript code:

import NhostClient from '@nhost/nhost-js';

const nhost = new NhostClient({
  subdomain: 'your-subdomain',
  region: 'your-region',
});

await nhost.auth.signIn({
  email: 'elon@musk.com',
  password: 'spaceX',
});

await nhost.graphql.request(`
  query {
    users {
      id
      displayName
      email
    }
  }
`);

This code snippet resembles ordering your favorite dish at a restaurant. First, you inform the restaurant (Nhost) of your order (sign in) using your credentials (email and password). After confirming your order, you can ask for the menu items (GraphQL request) to see what’s available.

Nhost’s Frontend Compatibility

Nhost isn’t picky; it’s frontend agnostic, meaning it can be seamlessly integrated with various frontend frameworks. Here are a few options:

• Next.js
• React
• React Native
• Vue

Troubleshooting Common Issues

As with any technology, users may encounter issues during setup or implementation. Here are a few troubleshooting ideas:

• Authentication Problems: Ensure you’re using the correct email and password patterns when signing in.
• API Responses: Check the GraphQL syntax if you receive unexpected results; misformatted queries can lead to confusion.
• Integration Errors: Double-check any framework-specific integrations to confirm compatibility with Nhost.
