[Halo sobat]
Melanjutkan https://dev.to/irpankusuma/upload-file-dengan-xhr-2a3a. Sekarang saya akan menampilkan script API dengan ExpressJSnya. Pertama saya harap Anda sudah biasa menggunakan expressjs dan sudah pernah membuat sebuah API.
Kemudian sebelumnya install package multiparty berikut ini
npm i connect-multiparty
Selanjutnya dalam file route yg akan digunakan codenya seperti berikut ini
upload.js
const router = require("express").Router();
const CPM = require("connect-multiparty");
const helper = require('helper.js');
const multiparty = CPM();
const target_path = `target_path`;
///// route file for access data from API
router.post("/", multiparty, async (req, res, next) => {
try {
const file = req.files.upload.path;
let obj = {
files: req.files,
temp: req.files.upload.path,
filename: req.files.upload.originalFilename,
ext: req.files.upload.type,
target_path: target_path,
};
///// file berikut yg bertugas melakukan transfer file
///// dari temp file ke local folder pada API project
await helper.uploadFile(obj, file, target_path)
.then(async (r) => {
let data = {
image_type: r.data.ext,
real_path: r.data.target_path,
real_filename: r.data.filename,
};
res.status(200).send(r);
})
.catch((e) => {
throw e;
});
} catch (err) {
res.status(401);
console.log(`error ${err}`)
}
});
module.exports = router;
Kemudian selanjutnya adalah create helper.js
helper.js
const fs = require('fs')
const mv = require('mv')
module.exports = {
uploadFile: (obj={},tmp_path,path) => {
return new Promise((resolve,reject) => {
try {
const filename = path+obj.filename;
if(!fs.existsSync(path)){
fs.mkdirSync(path);
mv(tmp_path,filename,function(err){
if(err) reject(err)
fs.unlink(tmp_path,function(){
if(err) reject(err)
resolve({status: true, message: 'Data uploaded success'})
})
})
} else {
mv(tmp_path,filename,function(err){
if(err) reject(err)
fs.unlink(tmp_path,function(){
if(err) reject(err)
resolve({status: false, message: 'Data uploaded failed!'})
})
})
}
} catch (error) {
reject(error)
}
});
}
}
Dalam expressJS mapping file upload.js pada routing seperti berikut ini
const router = require('express').Router()
router.use('/upload',require('./upload'))
Selanjutnya Anda bisa mencoba menggunakan postman seperti berikut
