0L Explorer

Structure of this repo:

This repository contains the code for the 0L Network explorer and is structured in the following way:

• api: This directory contains the backend in Nest.js, the source for transformer binary and the required migration files.
• infra: This directory contains the K8s YAML files for deployment on K8s.
• ol-fyi-local-infra: This directory contains files for setting up the databases locally using docker-compose.
• web-app: This directory contains the client-side code for the 0L Explorer app.

Local Setup:

This documentation will walk you through setting up and running the Wallet Explorer project locally from scratch. Follow these steps carefully to ensure a smooth setup process:

Prerequisites

Before you begin, ensure you have the following installed on your system:

1. Docker: Install Docker
2. Node.js and npm:

• Install nvm (Node Version Manager) from the nvm GitHub repository.
• Use nvm to install and use the Node.js version specified in your project's .nvmrc file:

  nvm install
  nvm use

3. Rust and Cargo: Install Rust

Once you are set, follow the steps:

• First, set up all the necessary components using Docker Compose.

• Navigate to the ol-fyi-local-infra directory.

  cd ./ol-fyi-local-infra

• Once you are in the ol-fyi-local-infra directory, run:

  docker compose up -d

This brings all the databases up:

• Redis
• Clickhouse
• NATS
• Postgres

Check the status using:

docker ps

Running Clickhouse Migrations

Once the Clickhouse database is up and running, you can connect to it and execute using:

docker compose exec -it clickhouse clickhouse client -h "127.0.0.1" --port 9000 -u "olfyi" --password "olfyi" -n

After connecting to the clickhouse client, execute the queries to run the migrations stored in the tables_local.sql file manually.

docker compose exec -T clickhouse clickhouse-client --database=olfyi -n < ../api/tables_local.sql

Building the Transformer Binary

Navigate to the transformer directory and build the project:

cd ./api/transformer

Build the binary:

cargo build

Run the backend

Navigate to api directory.

cd api

Prerequisites

nvm install
nvm use

PostgreSQL

We use Primsa.

• Run npx prisma generate if you update api/prisma/schema.prisma.
• Run npx prisma db push to migrate the database.

Installation

First, install the project dependencies:

npm install

Don't forget to configure the .env on your machine

cp .env.example .env

Running the app

To run your Nest application, use the following commands:

# development
npm run start

# watch mode
npm run start:dev

# production mode
npm run start:prod

Run the client:

Once the backend is running, run the client,

cd web-app

First, install the project dependencies:

npm install

And run it with:

npm run dev
