A very simple typescript whatsapp gateway via expressjs REST API using whatsapp-web.js.

• For more process-oriented whatsapp bot without a REST API, you can visit:https://github.com/snowfluke/wajs-bot-boilerplate
• For dial-based bot whatsapp, visit:https://github.com/snowfluke/dial-wabot-boilerplate

Any features request and contribution are welcome! ^_^

1. Make sure you clone this repo first
2. Copy.env.example and rename it to.env
3. Change the configuration there
4. Don't forget to change thelogo.jpg in the root directory

1. Node.js v20+ , I've setups to 20 in package.json, you can change it but generally it works in Node.js v12 higher
2. npm package manager
3. You can go for docker for an easy setups, or if you deploy it manually you will need to install Google Chrome
4. On an Ubuntu server, you will need to run this command:

sudo apt-get update&& sudo apt-get install -y \    gconf-service \    libgbm-dev \    libasound2 \    libatk1.0-0 \    libc6 \    libcairo2 \    libcups2 \    libdbus-1-3 \    libexpat1 \    libfontconfig1 \    libgcc1 \    libgconf-2-4 \    libgdk-pixbuf2.0-0 \    libglib2.0-0 \    libgtk-3-0 \    libnspr4 \    libpango-1.0-0 \    libpangocairo-1.0-0 \    libstdc++6 \    libx11-6 \    libx11-xcb1 \    libxcb1 \    libxcomposite1 \    libxcursor1 \    libxdamage1 \    libxext6 \    libxfixes3 \    libxi6 \    libxrandr2 \    libxrender1 \    libxss1 \    libxtst6 \    ca-certificates \    fonts-liberation \    libappindicator1 \    libnss3 \    lsb-release \    xdg-utils \    wget

5. cd into the project directory
6. runnpm install
7. runnpm run build
8. runnpm run start
9. After that you will need to scan the QR that is printed to the terminal
10. You're basically done, or if you want to be more robust, you can usepm2 for a better process management
