Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

NOTED

  • npm install @agustriadji/upload-files --save
  • setting file .env , config/upload.js dan app/middleware/upload.js.

Config File Uplaod

  1. .env

    FILE_MANAGER_URL dan FILE_MANAGER_PORT : atur url dan port untuk dihubungkan pada service file-manager pada server 12.

  2. .config/upload.js

    Disini mengatur filter file seperti :

    • urlStore : API Address untuk request upload.
    • urlGet : API Address untuk request view file / download file.
    • fileSize : Nilai Maksimum dari filesize yang diperbolehkan, satuan (byte).
    • prefixFile : Nama prefix file.
    • filePath : Pengaturan path upload yang akan disimpan pada servis file-manager.
    • fileExt : Filter extension yang diperbolehkan.
    • limits : Pengaturan pembatasan request terkait attack ddos.
    • fileTmp : Pengaturan path temporary yang akan dipakai sementara.
    • error : Pengaturan pesan gagal untuk middleware upload.

Setup Middleware Upload

  • Buat file upload.js pada dir app/middleware/upload.js

    module.exports = {
        files_upload: libUpload.files_upload,
        multer_err: libUpload.multer_err,
        sendToFileManager: libUpload.sendToFileManager,
        getFileManager: libUpload.getFileManager,
    };```
    
  • Buat file app/middleware/index.js untuk daftarkan file upload.js

    module.exports = {
        upload: require('./upload'),
    };

Setup Middleware Upload Pada RoutesAPI

const middle = require('../../middleware');
const middleUpload = middle.upload;

fieldname 'file' yang digunakan untuk mengirim file upload.

const upload = middleUpload.files_upload.single('file');
app.route(YOUR_API)
.post(middle.permission, (req, res) => {
    upload(req, res, (err) => {
        if (err instanceof middleUpload.multer_err) { // Handle Unknown Error
            const msg = {
                header: {
                    message: err.message,
                    status: 500,
                },
                data: { code: err.code },
            };
            return res.status(500).json(msg);
        }
        if (err) { return res.status(500).json(err); }
        controller.create(req, (result) => {
            result.header.access = req.param.access.data.access;
            res.status(result.header.status).json(result);
        });
    });
});

Setup SendToFileManager untuk handle upload, replace , delete Pada Controller

const { sendToFileManager } = require('@agustriadji/upload-files');
sendToFileManager(data, (err, value) => {
    if (err) return next(true, value);
    return next(null, data);
});

sendToFileManager memiliki 2 param :

  • param pertama type object dengan attribute name

    { filename: String, path: String, action:String }.

  • param kedua berupa callback(error, result)

    error type String dan result type Object.

Penggunaan sendToFileManager

  • UPLOAD

    param pertama = { filename: String, path: String, action:String }.

  • REPLACE

    param pertama = { currentFilename: String, filename: String, path: String, action:'replace' },

    currentFilename = filename yang disimpan pada DB, tujuannya tidak merubah nama file hanya merubah data file dengan ext yang sama.

    filename = filename yang diterima oleh request client.

    path = nilai yang di ambil dari config/upload.js (filePath)

  • DELETE

    param pertama = { filename: String, path: String, action:'delete' },

    filename = filename yang telah diambil dari DB.

    path = nilai yang di ambil dari config/upload.js (filePath)

Setup getFileManager untuk download pada Controller

getFileManager(data, (value) => {
    if (value.status !== 200)
        return next(buildRes.error.data_notFound, null);
    const paths = './tmp/${data.filename}';
    return next(null, paths);
});

getFileManager memiliki 2 param :

  • param pertama type object dengan attribute name

    { filename: String, path: String}.

  • param kedua berupa callback(error, result)

    error type Object dan result type Object.

Penggunaan getFileManager

  • DOWNLOAD

    param pertama = { filename: String, path: String },

    filename = data filename yang telah diambil dari DB.

    path = data path yang telah diambil dari DB.

  • VIEW

    param pertama = { filename: String, path: String },

    filename = data filename yang telah diambil dari DB.

    path = data path yang telah diambil dari DB.
