Welcome to your user-friendly guide on Fireward, an innovative language and compiler designed specifically for writing Firestore security rules. With its idiomatic type validation system, Fireward makes it feasible to add strict type-checking to your routes, simplifying your coding experience. Let’s dive into how to get started with Fireward and unlock its powerful features!

Installation Methods

Before we can write our security rules, we need to install Fireward. Here are three simple methods for installation:

• Method 0: NPM
  Run the following command in your terminal to install Fireward globally:
  

  npm install -g fireward

• Method 1: Binary
  Download a release binary and place it in your system’s PATH.
• Method 2: Compile Yourself
  1. Download the Haskell Stack tool and add it to your PATH.
  2. Navigate to the project directory and run:
  

  stack install

  
  This will download and compile everything for you.
• Method 3: Use Docker Image
  If you prefer using Docker, install Docker and run the following commands:
  

  cat definitions.ward | docker run --rm -i -a stdout -a stdin bijoutrouvaille/fireward > generated.rules

  
  For TypeScript definitions:
  

  cat definitions.ward | docker run --rm -i -a stdout -a stdin bijoutrouvaille/fireward -c --lang=typescript > generated.ts

Writing Your Own Firestore Rules

Once installed, you can start writing your Firestore rules using the Fireward’s syntax which is similar to TypeScript. Here’s a beginner-friendly breakdown of how to define and apply a type within Fireward:

Think of your coding process as a crafting session where you’re making a beautiful cake. The cake is your Firestore security rule, and every ingredient (type) affects the flavor and texture of the final product.

• Define a Type: Just like choosing your cake ingredients, you define your types, such as name, email, or user.
• Assign to Routes: Following the recipe, assign your defined types to specific routes, ensuring each layer (route) has the right attributes (types).

For example:

type Name = { first: string, last?: string }
type User = { name: Name; email: string }

match users/{id} is User {
    allow read: true;
    allow create, update: request.auth != null;
    allow delete: false;
}

Utilizing Fireward’s Features

Fireward is not only about making rules; it offers elegant features to express validations effortlessly:

Troubleshooting

Every journey has its bumps! Here are some troubleshooting tips to smooth your Fireward experience:

• If you encounter errors during type definitions, ensure your syntax matches TypeScript formats.
• To resolve compilation issues, double-check that your Haskell Stack is properly installed and updated.
• When working with Docker, verify your image is correctly pulled and that Docker is running.
