To build and start the PingCAP Autoflow project, follow the detailed steps below. This guide includes examples and references to key files and commands necessary for building and running the project.

Prerequisites

Ensure that you have the following tools installed on your system:

• Node.js (v12 or later)
• Docker
• Make

Step 1: Clone the Repository

Clone the Autoflow repository from GitHub to your local machine.

git clone https://github.com/pingcap/autoflow.git
cd autoflow

Step 2: Install Dependencies

Navigate to the autoflow directory and install the required Node.js dependencies.

npm install

This command will read the package.json file located in the root directory and install all necessary libraries.

Step 3: Build the Project

Build the project using the following command, which will compile the TypeScript files and bundle the application for production.

npm run build

The scripts defined in package.json handle the build process, and the output will typically be found in a directory like dist/.

Step 4: Configure Environment Variables

Before starting the project, set up any necessary environment variables. This may include API keys, database connections, or specific application settings. Create a .env file in the root directory if one does not already exist.

Example of a typical .env setup:

DATABASE_URL=your_database_url
API_KEY=your_api_key

Ensure that you fill in the values with appropriate configurations for your environment.

Step 5: Build and Start with Docker

If using Docker, the project includes a Dockerfile which will be utilized to create a container image for autoflow. To build and run the Docker container, use the following commands:

5.1 Build the Docker Image

docker build -t autoflow .

5.2 Run the Docker Container

Run the Docker container, ensuring to expose the necessary port.

docker run -p 3000:3000 autoflow

The above command exposes port 3000, as specified in the Dockerfile, allowing access to the application through this port.

Step 6: Start the Application

If not using Docker, you can start the application directly using Node.js.

npm start

This command will execute the start script defined in your package.json, typically pointing to the entry file of your application.

Step 7: Verify the Application

Open a web browser or API client and navigate to http://localhost:3000 to verify that the application is running as expected.

Conclusion

These steps outline the process of building and starting the PingCAP Autoflow project. Ensure that all commands are executed in the appropriate directory and that necessary configurations are made beforehand.
