Project Structure

WhatsApp-Api-NodeJs

This code is an implementation of WhiskeySockets, as a RestFull Api service, which controls whatsapp functions.
With this one you can create multiservice chats, service bots or any other system that uses whatsapp. With this code you don't need to know javascript for nodejs , just start the server and make the language requests that you feel most comfortable with.

Infrastructure

1. Docker installation

  • First, let's install Docker. Docker is a platform that allows us to quickly create, test and deploy applications in isolated environments called containers.
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker ${USER}

2. Installing the database

PostgreSql [required]

  • Now, we have configured our PostgreSQL database using Docker Compose.
  • Access your postgre manager and create a database.

compose from postgres

3. Nvm installation

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
# or
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

After finishing, restart the terminal to load the new information.

3.1 Nodejs installation

  • Installing Node.js using NVM, a version manager that allows us to switch between different versions of Node.js easily.
nvm install 20

4. pm2 installation

npm i -g pm2

5. Application startup

Cloning the Repository

git clone https://github.com/code-chat-br/whatsapp-api.git

Go to the project directory and install all dependencies.

Give preference to npm as it has greater compatibility.

cd whatsapp-api-v2

npm install
# or
npm install --force

6. Environment variables

See additional settings that can be applied through the env file by clicking here.

⚠️Attention⚠️: copy the .env.dev file to .env.

cp .env.dev .env

7. Prism ORM

  • We're going to use Prisma ORM to manage our database. Prisma simplifies database access and ensures operations are secure and easy to maintain.
  • Commands and Explanations:
    • In development environment: npx prisma migrate dev
      • We use migrate dev in development to automatically create and apply migrations, making working with the database easier.
    • In production environment: npx prisma migrate deploy
      • In production, we use migrate deploy to apply migrations in a controlled and secure way.
    • Data visualization: npx prisma studio
      • Prisma Studio is a visual tool that helps us manage and visualize bank data in an intuitive way.

Define the DATABASE_URL environment variable for the database deployment.

bash deploy_db.sh

Finally, run the command below to start the application:

npm run start:dev

npm run start:prod

# pm2
pm2 start 'npm run start:prod' --name CodeChat_API_v1.3.0

Worker

Worker options for session management

To use the worker with the API it is necessary to define the following environment variables in the API:

  • PROVIDER_ENABLED=true: This variable enables the use of the provider (worker) in the API.
  • PROVIDER_HOST=127.0.0.1: Defines the host where the worker is listening for requests.
  • PROVIDER_PORT=5656: Defines the port where the worker is listening for requests.
  • PROVIDER_PREFIX=codechat: Set prefix for instance grouping on worker

WebSocket

websocket compatibility added. Read here.

Swagger - OpenAPI 3.0.0

Authentication

You can define two authentication types for the routes in the env file. Authentications must be inserted in the request header.

  1. jwt: A JWT is a standard for authentication and information exchange defined with a signature.

Authentications are generated at instance creation time.

Note: There is also the possibility to define a global api key, which can access and control all instances.

App in Docker

After building the application, in the same directory as the files above, run the following command:

docker-compose up
