This is a TypeScript module that provides functions to parse a multipart body buffer and extract its parts based on the provided boundary. It also includes utility functions to extract the boundary string from the Content-Type header and generate sample demo data for testing.
This module is written in TypeScript and can be added to your project using npm:
npm install multipart-form-readerimport { readForm, setMaxFileSize } from 'multipart-form-reader';
import express from 'express';
import fs from 'fs';
const app = express();
const router = express.Router();
//10MB
const SIZE = 10 * 1024 * 1024;
setMaxFileSize(SIZE);
app.get('/', (req, res) => {
res.send('Hello World!');
});
router.post('/', readForm, (req, res) => {
console.log('File upload request received');
//console.log('req.files', req.files);
//console.log('req.body', req.body);
//write the file to disk
//create upload directory if it doesn't exist
if (!fs.existsSync('./uploads')) {
fs.mkdirSync('./uploads');
}
//write the file to disk
fs.writeFileSync('./uploads/' + req.files[0].filename, req.files[0].data);
res.send('File uploaded');
});
app.use('/test', router);
app.listen(3000, () => {
console.log('Example app listening on port 3000!');
});
