Imba is a friendly full-stack programming language for the web that

compiles to performant JavaScript. It has language-level support for

defining, extending, subclassing, instantiating and rendering DOM

nodes.



## Get started



Try Imba instantly in your browser with our

[playground](https://imba.io/try/examples/apps/playground/app.imba),

or create a new project with:



```sh

npx imba create

```



## Documentation



To get started with Imba, we recommend reading through the [official guide](https://imba.io/).



## Why Imba?



### Minimal syntax



Imba's syntax is minimal, beautiful, and packed with clever features. It combines logic, markup and styling in a powerful way. Fewer keystrokes and less switching files mean you'll be able to build things fast.



```imba

import './util/reset.css'



global css html,body m:0 p:0 w:100% h:100%



tag login-form < form



	css input rd:md bc:gray3 h:20px fs:md

	css button rd:md c:white bg:gray4 @hover:blue4



	

		

		

		 "Login as {name}"



imba.mount 

```



### Runs on both server and client



Imba powers both the frontend and the backend of Scrimba.com, our learning platform with 100K+ monthly active users. On the frontend, Imba replaces e.g., Vue or React, and on the backend, it works with the Node ecosystem (e.g., npm).



```imba

import express from 'express'

import services from './services.ts'

import html from './index.html'

import image from './confused-cat.png'



const app = express!



app.get '/404' do (req,res)

	res.send String  

		

		
 "We could not find this page!"



app.get '/' do (req,res)

	res.send html.body

```



### Integrated styling



Inspired by Tailwind, Imba brings styles directly into your code. Styles can be scoped to files, components, and even parts of your tag trees. Style modifiers like @hover, @lg, @landscape and @dark can be used for extremely concise yet powerful styling.



```imba

# global styles

global css button

	position: relative

	display: block

	background: #b2f5ea

	@hover background: #b2f9ea



# tailwind-inspired shorthands

global css button

	pos:relative d:block bg:blue5 bg@hover:blue6



tag App

	# scoped styles

	css item bg:blue4 m:2



	 # inline styles

		
     for {type,title} in items

    			 title

    ```
    


    ### Blazing fast, Zero config
    


    Imba comes with a built-in bundler based on the blazing fast esbuild. Import stylesheets, images, typescript, html, workers and more without any configuration. Bundling is so fast that there is no difference between production and development mode - it all happens on-demand.
    


    ```imba

    # importing a worker

    const worker = import.worker './analyzer'

    const analyzer = new Worker(worker.url)

    # import an image

    const logo = import './images/logo.png'

    console.log "logo size: {logo.width}x{logo.height} - at {logo.url}"

    ```
    


    When you run your app with the `imba` command, it automatically bundles and compiles your imba code, along with typescript, css and many other file types. It provides automatic reloading of both the server and client.
    


    ### Typing and tooling
    


    The tooling is implemented as a typescript server plugin giving us great intellisense, diagnostics, and even cross-file refactorings that works with js/ts files in the same project. You can import types just like in typescript, and annotate variables, parameters and expressions. Like the language, the tooling is still in alpha, but improving every day.
    


    ```imba

    import type { CookieOptions } from 'express-serve-static-core'
    


    def flash res\Response, body\string, settings = {}

    	let options\CookieOptions = {

    		...settings

    		maxAge: 86400

    		secure: true

    		httpOnly: false

    	}
    


    	res.cookie('flash',body,options)

    ```
