Proxy App

This is a simple proxy application built with Node.js and Express.js. It allows you to proxy HTTP requests to a specified target URL.

Features

• Proxy HTTP requests to a target URL
• Modify response headers and body
• Support for custom schema parameters in response payload

Getting Started

To get started with the Proxy app, follow these steps:

Prerequisites

• Node.js installed on your machine
• npm (Node Package Manager) or yarn

Installation

1. Clone the repository:

git clone <repository-url>

2. Navigate to the project directory:

cd helsinki-crawler-proxy

3. Install dependencies:

npm install

Configuration

1. Create a .env file in the root directory of the project.
2. Set the following configuration parameters in the .env file:

PROXY_HOST=example-proxy.metatavu.io
PROXY_PORT=3128
PROXY_PROTOCOL=https
PROXY_USERNAME=proxyuser
PROXY_PASSWORD=proxypass

Starting the Server

To start the server, run:

npm start

The server will start listening on port 3000 by default. You can change the port by setting the PORT environment variable in the .env file.

Development

To start development mode with hot reloading, run:

npm run dev

This command uses nodemon to watch for changes in your files and automatically restarts the server.

Usage

Once the server is running, you can make HTTP requests to http://localhost:3000/proxy and specify the target URL in the Proxy header.

For example:

curl --head --proxy http://localhost:3000 http://www.google.com

This command will send a HEAD request to http://www.google.com through the proxy server running on http://localhost:3000.
