Static Files ​

You can use the serveFile function from the @wooksjs/http-static package to serve static files. This function returns a readable stream of the file content and takes care of preparing the necessary response headers, handling caching, and supporting range requests.

Installation ​

To use the static file serving functionality, you need to install the @wooksjs/http-static package:

npm install @wooksjs/http-static

Usage ​

Once installed, you can import the serveFile function and use it in your Moost HTTP application.

Example:

import { serveFile } from '@wooksjs/http-static';
import { Controller, Get } from '@moostjs/event-http';

@Controller()
class MyController {
  @Get('static/file.txt')
  serveStaticFile() {
    return serveFile('file.txt', options);
  }
}

The serveFile function takes the file path as the first argument and accepts an optional options object as the second argument. It returns a readable stream of the file content that will be sent as the response.

Options ​

The options object allows you to customize the behavior of the file serving. It provides the following properties:

• headers: An object containing additional headers to add to the response.
• cacheControl: The Cache-Control header value for caching control. You can provide a string or an object with cache control directives.
• expires: The Expires header value to specify the expiration date/time of the file.
• pragmaNoCache: A boolean value indicating whether to add the Pragma: no-cache header.
• baseDir: The base directory path for resolving the file path.
• defaultExt: The default file extension to be added to the file path if no file extension is provided.
• listDirectory: A boolean value indicating whether to list files in a directory if the file path corresponds to a directory.
• index: The filename of the index file to automatically serve from the folder if present.

Built-in file server example: ​

Here's an example of using the serveFile function to create a built-in file server in a Moost HTTP controller:

import { serveFile } from '@wooksjs/http-static';
import { Get, Controller } from '@moostjs/event-http';
import { Param } from 'moost';

@Controller()
class MyController {
  @Get('static/*')
  serveStaticFile(@Param('*') filePath: string) {
    return serveFile(filePath, { cacheControl: { maxAge: '10m' } });
  }
}

In the example above, any request to the /static/* route will serve the corresponding file from the file system. The file path is extracted from the wildcard route parameter, and the cacheControl option is used to set the caching behavior of the response.

You can refer to the Cache Control documentation in Wooks for more details on how to configure the cache control directives.
