This blog post shows how to integrate SolidJS frontend library with AdonisJS backend framework. This will be a relatively short article. I think AdonisJS - SolidJS would be my favorite web development stack.


AdonisJS is a fully-featured Node.js framework. It follows the Model-View-Controller (MVC) pattern and has its own template engine, Object-Relational-Mapper (ORM), authorization, and authentication modules. I also wrote a post about AdonisJS and Tailwind CSS before.

On the other hand, SolidJS is a declarative, efficient, and flexible frontend library. Moreover, SolidJS is truly a reactive JavaScript library, unlike ReactJS. If you have developed a frontend application with React, you'll definitely love SolidJS.

Also, if you don't have any SolidJS experience before, I suggest reading SolidJS and Reactive Primitives.

AdonisJS Setup

We need to install AdonisJS 5 because our SolidJS application will be built on it.

yarn create adonis-ts-app adonis-solid-integration

I'm going to choose web as the project type.

/ \\ __| | ___ _ __ (_)___ | |___
/ _ \\ / _` |/ _ \\| '_ \\| / __|_ | / __|
/ ___ \\ (_| | (_) | | | | \\__ \\ |_| \\__ \\
/_/ \\_\\__,_|\\___/|_| |_|_|___/\\___/|___/
❯ Select the project structure … Press <ENTER> to select
api (Tailored for creating a REST API server)
❯ web (Traditional web application with server rendered templates)
slim (A smallest possible AdonisJS application)

After choosing the project type, other customization options will be appeared. Setting up Eslint totally up to you. However, you should enable Webpack Encore. Otherwise, your frontend assets will not be compiled.

❯ Select the project structure · web
❯ Enter the project name · adonis-solid-integration
❯ Setup eslint? (y/N) · false
❯ Configure webpack encore for compiling frontend assets? (y/N) · true
[ success ] Project created successfully
│ Run following commands to get started │
│ │
│ ❯ cd adonis-solid-integration │
│ ❯ node ace serve --watch │
│ │

Let change the current directory to the project directory.

cd adonis-solid-integration

SolidJS Setup

Installing SolidJS on an AdonisJS app alone is not enough because it uses JSX syntax. Therefore, we need to install babel-preset-solid babel plugin as a development dependency.

# Install SolidJS
yarn add solid-js
# Install Babel plugin
yarn add -D babel-preset-solid

We need to add the code below to webpack.config.js file.

| Encore Babel Configs
babelConfig => {
exclude: /node_modules/

AdonisJS uses Edge template engine. By default, the resources/views/welcome.edge is the default view for the homepage. As you know, it can be changed from start/routes.ts file. However, we need to modify the welcome.edge file so that we can render our Solid application inside the correct DOM element.

<!DOCTYPE html>
<html lang="en">
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>AdonisJS - A fully featured web framework for Node.js</title>
<div id="app"></div>

Open your main JavaScript file: resources/js/app.js and fill it like below:

// resources/js/app.js
import "../css/app.css";
import { createSignal, onCleanup } from "solid-js";
import { render } from "solid-js/web";
const App = () => {
const [count, setCount] = createSignal(0),
timer = setInterval(() => setCount(count() + 1), 1000);
onCleanup(() => clearInterval(timer));
const style = `
return <div style={style}>{count()}</div>;
render(() => <App />, document.getElementById("app"));

You'll easily notice the different styling syntax comparing to React. You can see other styling syntax in SolidJS.

Now you can start the app by executing the command below. Then you will see a timer on your screen.
