Formidable which helps you parse and get files from the POST request
Example code:
const formidable = require('formidable');
const fs = require('fs');
const path = require('path');
// POST | /upload
app.post('/upload', (req, res) => {
const form = new formidable.IncomingForm();
form.parse(req, (error, fields, files) => {
if(error){
res.status(500);
console.log(error);
res.json({
error,
});
return false;
}
const image = files.image;
console.log(image.name) // pony.png
console.log(image.type) // image/png
// Get the tmp file path
const tmpFilePath = image.path; // /tmp/<randomstring>
// Rename and relocate the file
fs.rename(tmpFilePath, path.join(`${__dirname}/uploads/${image.name}`), error => {
if(error){
res.status(500);
console.log(error);
res.json({
error,
});
return false;
}
res.status(201);
res.json({
success: true,
upload_date: new Date(),
});
// Do all kinds of MySQL stuff lol
});
});
});
