File upload software code example
Example: file uploading
const express = require('express');
const authenticate = require('../authenticate');
const multer = require('multer');
const storage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, 'public/images');
},
filename: (req, file, cb) => {
cb(null, file.originalname)
}
});
const imageFileFilter = (req, file, cb) => {
if(!file.originalname.match(/\.(jpg|jpeg|png|gif)$/)) {
return cb(new Error('You can upload only image files!'), false);
}
cb(null, true);
};
const upload = multer({ storage: storage, fileFilter: imageFileFilter});
const uploadRouter = express.Router();
uploadRouter.route('/')
.get(authenticate.verifyUser, authenticate.verifyAdmin, (req, res) => {
res.statusCode = 403;
res.end('GET operation not supported on /imageUpload');
})
.post(authenticate.verifyUser, authenticate.verifyAdmin, upload.single('imageFile'), (req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'application/json');
res.json(req.file);
})
.put(authenticate.verifyUser, authenticate.verifyAdmin, (req, res) => {
res.statusCode = 403;
res.end('PUT operation not supported on /imageUpload');
})
.delete(authenticate.verifyUser, authenticate.verifyAdmin, (req, res) => {
res.statusCode = 403;
res.end('DELETE operation not supported on /imageUpload');
});
module.exports = uploadRouter;
