To convert a file from an external link to a buffer using Nest js, you can use the Axios module to make a GET request to the external link and convert the response data to a buffer. Here is an example code snippet:
import { Injectable } from '@nestjs/common';
import axios from 'axios';
@Injectable()
export class FileService {
async getFileBuffer(url: string): Promise<Buffer> {
const response = await axios.get(url, { responseType: 'arraybuffer' });
const buffer = Buffer.from(response.data, 'binary');
return buffer;
}
}
In this example, we create a FileService
class with a getFileBuffer
method that takes a url
parameter and returns a promise that resolves to a buffer. We use the Axios module to make a GET request to the given url
and specify arraybuffer
as the response type. The response data is then converted to a buffer using the Buffer.from
method.
You can then inject this service into your controller or another service and use the getFileBuffer
method to get a buffer from an external file link.
