Safe Client Gateway

Motivation

The Safe Client Gateway serves as a bridge for the Safe{Wallet} clients (Android, iOS, Web).

It provides UI-oriented mappings and data structures for easier integration with several Safe{Core} services. In essence, it works as a bridge between the frontend and backend, ensuring smooth, efficient data exchange.

Documentation

Requirements

Node.js v22.11.0 'Jod' LTS (Node.js Release Schedule) – https://nodejs.org/en/
Docker Compose – https://docs.docker.com/compose/

Installation

Optional: If you have NVM installed, you can run nvm use in the root folder of the project to use the recommended Node version set for this project.

We use Yarn as the package manager for this project. Yarn is bundled with the project so to use it run:

corepack enable && yarn install

The project requires some ABIs that are generated after install. In order to manually generate them, run:

yarn generate-abis

Running the app

Start Redis instance. By default, it will start on port 6379 of localhost.

docker compose up -d redis

Start the Safe Client Gateway

# development
yarn run start

# watch mode
yarn run start:dev

# production mode
yarn run start:prod

Test

The unit test suite contains tests that require a database connection. This project provides a db-test container which also validates the support for SSL connections. To start the container, make sure that the key for the self-signed certificate has the right permissions.

# disallow any access to world or group
chmod 0600 db_config/test/server.key

With the right permissions set on the server.key file we can now start the db-test container:

# start the db-test container
docker compose up -d db-test

# unit tests
yarn run test

# e2e tests
docker-compose up -d redis rabbitmq && yarn run test:e2e

# test coverage
yarn run test:cov

Linter and Style Guide

We use ESLint as a linter and Prettier as a code formatter. You can run yarn run lint to execute ESLint and yarn run format to execute Prettier.

These checks can be automatically executed using Git hooks. If you wish to install the provided git hooks:

yarn install
yarn husky install
