Installation

1. Clone the repository:

   git clone https://github.com/your-repo/project-name.git
   cd project-name

2. Install dependencies:

   npm install

3. Set up environment variables: Create a .env file in the root directory and add the following:

   ACCOUNT_NAME=your_account_name
   SAS_TOKEN=your_sas_token
   CONTAINER_NAME=your_container_name
   UPLOADS_PATH=path_to_uploads_directory

4. Build and start the server:

   npm run build
   npm run dev

Usage

Starting the Server

To start the server, run:

npm run dev

The server will start on the port specified in the configuration (default is 1209).

Configuration

AppConfig

• port: The port on which the server will run. Default is 1209.

Environment Variables

• ACCOUNT_NAME: Your Azure Blob Storage account name.
• SAS_TOKEN: Your Azure Blob Storage SAS token.
• CONTAINER_NAME: The name of your Azure Blob Storage container.
• UPLOADS_PATH: The path to the directory where uploads will be stored.

Endpoints

Uploads

• POST /api/uploads/images: Uploads a new image to Azure Blob Storage using Multer and returns the URI.

Static Files

• GET /api/uploads/*: Serves static files from the uploads directory.

Middleware

Multer

Multer is used for handling file uploads. It is configured to handle image uploads and store them in the specified UPLOADS_PATH.

Here is an example of how Multer is set up in the server:

import multer from 'multer';

const storage = multer.diskStorage({
  destination: (req, file, cb) => {
    cb(null, UPLOADS_PATH);
  },
  filename: (req, file, cb) => {
    cb(null, file.originalname);
  },
});

const upload = multer({ storage });

app.post('/api/uploads/images', upload.single('file'), (req, res) => {
  // Handle the uploaded file here
});

Error Handling

The server uses a centralized error handling middleware ExpressErrorHandler. Errors will be logged and appropriate HTTP status codes and messages will be returned.

Logging

The server uses a custom Logger for logging information and errors. Logs include information about server startup, database connections, and errors.
