labelflow VS vite

It is launch day for us at LabelFlow, the open platform for image labeling, would be great to get your feedback on this major update for us.

We are hosting image datasets on our platform and until recently the stored datasets were relatively small (several hundreds of images, few GB) so we only offered the possibility to export zip files containing images and labels in the COCO or YOLO format. As the average size of the datasets is growing, it's not convenient anymore to export a zip.

SWC in NextJS is still in canary with experimental settings, but it took me 3 lines of code yesterday to make it work on a fairly large app ( https://labelflow.ai ). Hot reload times instantly went from 10s to 1s. Twitter discussion here https://twitter.com/vlecrubier/status/1448371633673187329?s=...

Overall I’m pretty bullish on Rust tooling and integration within the JS/ Wasm ecosystem !

Check labelflow.ai. It's free, the code is published, web UI is super simple and the images do not need to be uploaded on remote servers so you get started in no time. For classification you would press the 1 key if image has hotdog else right key to go to the next image. Not gonna lie, you're going to need a bit of time for 10k images but definitely doable alone on a simple use case like that. To be fully transparent, I work there! Classification features are still in beta they will be released in 2 weeks. Happy labeling!

I’ve used storybook for 4 years in teams of 1-15 devs and I’d say it’s a must have for any serious react app with 3+ full time developers. It has its rough edges sure but the ROI is 10x nonetheless in my experiences.

Advantages

- Testing components in isolation forces some good practices and allows to keep the codebase in check by encouraging good practices (limited coupling of unrelated parts of the codebase

- It’s super productive because it is both a form of unit tests, useful during development of UX in « TDD mode », and a very good documentation of your UI components. It greatly reduces the effort needed for both these aspects.

- For DX, the hot reload is generally faster in storybook than in the App (except if you use vite/snowpack in your app, so far..) because reloading a single component is faster than reloading the whole app and its state. In a large CRA our hot reload could sometimes take up 1min in complex cases, while storybook was taking 3s.

- Coupled with Chromatic (their hosted platform) and its GitHub integration it makes QA and visual regression testing a joy, 10x faster than alternatives, I really recommend that.

- It allows to share/iterate easily your ongoing developments with non-tech people in your organisation at early stage. A very good bridge between Figma and the final UI. A good support during Daily meetings about UI, just shared the deployed story url to ask for feedback.

Drawbacks

- It has its own Webpack config. So if you have a custom Webpack config in your app (don’t do that anyway, unless absolutely necessary) then be prepared to duplicate the customizations in your storybook config

- Global React Contexts needs to be duplicated in your storybook config and, if necessary, configured for individual stories. For example if your signup button changes based on an Auth status stored in a global context, then you will have to use Story.parameters to customize the content of the Auth context.

- We had a couple instances where storybook was the limiting factor for us to embrace some new/fancy tech, like yarn v2 or service worker. However maybe that’s a good litmus test: things that storybook support are state of the art JS and generally safe to use. Things that storybook does not support out of the box will cause you problems with other tools anyway: if it’s not storybook, some other tool like Cypress, Jest, Next, or some browsers will cause you trouble with your “shiny new tech”

- It can be slow to startup. We had a storybook with 300+ complex stories and it took 5min to startup and 10min to build in the CI

- It had some API changes/ migration pains a couple years back. However I think the new API is very good and will last a long time so this is behind.

Overall I definitely advocate to use storybook, especially with Chromatic, the ROI is 10x. If you find yourself limited by it in 2021 despite configuring it, maybe question your own tech stack.

Don’t try to implement your own storybook copycat (we had a colleague develop an alternative https://github.com/remorses/vitro , but i think it was not worth the effort)

If you want to see a state of the art repo in NextJS that uses storybook extensively with some customizations, check https://github.com/Labelflow/labelflow/

As a matter of fact, LabelFlow uses a service worker exactly to avoid sending your data to a server (your data is stored in the local service worker instead). The code of this service worker is there: https://github.com/labelflow/labelflow/blob/main/typescript/web/src/worker/index.ts . You won't find any privacy-defeating stuff in there. It's super simple.

What was then just a landing page is now a product that you can try for free with no login required, the code is also publicly available on GitHub. (https://github.com/Labelflow/labelflow/).

4 months ago we announced Labelflow (https://www.labelflow.ai/), the open image annotation and dataset cleaning platform.

What was then just a landing page is now a product that you can try for free with no login required, the code is also publicly available on GitHub. (https://github.com/Labelflow/labelflow/).

In this first version, we are releasing your most wanted features: a straightforward online image annotation tool. For privacy concerns, your images are never uploaded to our server! You can create bounding boxes, polygons, export labels to COCO format and we added plenty of keyboard shortcuts for productivity!

We’re excited to hear your feedback, tell us what features would make your life easier (https://labelflow.canny.io/feature-requests) and upvote what you would like us to build. Stay tuned, It’s just the beginning of a long story.

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react-swc' import path from 'path' // https://vitejs.dev/config/ export default defineConfig({ plugins: [react()], server: { port: 3000 }, css: { devSourcemap: true }, resolve: { alias: { '~': path.resolve(__dirname, './src') } } })

I am currently utilizing Vite:

Homepage: https://vitejs.dev/

Without any adding any dependencies you can connect react props to raw css at runtime with nothing but css variables (aka "custom properties"). If you add CSS modules on top you don't have to worry about affecting the global scope so components created in this way can be truly modular and transferrable. I use this with vite.

Little confused as to why it has vite in it‘s name, it seems unrelated to https://vitejs.dev/

it says in their docs that they recommend Vite https://vitejs.dev/

it goes like this.

1. you create a repo folder, you cd into it.

2. you create a client template using vite which can be plain typescript, or uses frameworks such as react or vue, at https://vitejs.dev/guide/

3. you cd in that client directory, you npm install, then you npm run dev, it should show you that it works at localhost:5173

4. you follow the instructions on your url, you do npm install @web3modal/wagmi @wagmi/core @wagmi/connectors viem

5. you follow the further instructions.

> It seems like this is for npm or yarn to pull from a remote repository maintained by @wagmi for instance. But then what?

you install the wagmi modules, then you import them in your js code, those code can run upon being loaded or upon user actions such as button clicks

> Do I just symlink to the node_modules directory somehow? Use browserify? Or these days I'd use webpack or whatever the cool kids are using these days?

no need for those. browserify is old school way of transpiling commonjs modules into browser-compatible modules. webpack is similar. vite replaces both webpack and browserify. vite also uses esbuild and swc under the hood which replaces babel.

> I totally get how node package management works ... for NODE. But all these client-side JS projects these days have docs that are clearly for the client-side but the ES2015 module examples they show seem to leave out all instructions for how to actually get the files there, as if it's obvious.

pretty much similar actually. except on client-side, you have src and dist folders. when you run "npm run build" vite will compile the src dir into dist dir. the outputs are the static files that you can serve with any http server such as npx serve, or caddy, or anything really.

> What gives? And finally, what exactly does "browserify" do these days, since I think Node supports both ES modules and and CJS modules? I also see sometimes UMD universal modules

vite supports both ecmascript modules and commonjs modules. but these days you'll just want to stick with ecmascript which makes your code consistently use import and export syntax, and you get the extra benefit of it working well with your vscode intellisense.

> In short, I'm a bit confused how to use package management properly with browsers in 2024: https://modern-web.dev/guides/going-buildless/es-modules/

if people want plain js there is unpkg.com and esm.sh way, but the vite route is the best for you as it's recommended and tested by the providers of your modules.

> And finally, if you answer this, can you spare a word about typescript? Do we still need to use Babel and Webpack together to transpile it to JS, and minify and tree-shake, or what?

I recommend typescript, as it gives you better type-safety and better intellisense, but it really depends. If you're new to it, it can slow you down at first. But as your project grows you'll eventually see the value of it. In vite there are options to scaffold your project in pure js or ts.

First you have to know that all those react projects are created using Vite, and for each of them, you need change the vite.config.ts file by adding the following configuration:

CSSHooks works with React, Prereact, Solid.js, and Qwik, and we’re going to use Vite with the React configuration. First, let's create a project called css-hooks and install Vite:

JavaScript React Flowbite Tailwind Firebase - Auth, Database, and Hosting Vite

For this full-stack single-page app, you'll use Vite.js as your frontend build tool and the react-beautiful-dnd package for draggable items.
