Build a Full-Stack SolidStart Application

Create a simple todo app with Remult using SolidStart

In this tutorial, we are going to create a simple app to manage a task list. We'll use SolidStart, and Remult as our full-stack CRUD framework. For deployment to production, we'll use and a PostgreSQL database.

By the end of the tutorial, you should have a basic understanding of Remult and how to use it to accelerate and simplify full stack app development.

You want to have a look at the end result ?

You can degit the final result and read the file in the project to check it out.

npx degit remult/remult/examples/solid-start-todo remult-solid-start-todo
cd remult-solid-start-todo


This tutorial assumes you are familiar with TypeScript, Solid and SolidStart.

Before you begin, make sure you have Node.js and git installed.

Setup for the Tutorial

This tutorial requires setting up a SolidStart project and a few lines of code to add Remult.

You can either use a starter project to speed things up, or go through the step-by-step setup.

Option 1: Clone the Starter Project

  1. Clone the remult-solid-start-todo repository from GitHub and install its dependencies.
git clone remult-solid-start-todo
cd remult-solid-start-todo
npm install
  1. Open your IDE.
  2. Open a terminal and run the dev npm script.
npm run dev

The default SolidStart app main screen should be displayed (except for the styles which were modified for the tutorial).

At this point, our starter project is up and running. We are now ready to move to the next step of the tutorial and start creating the task list app.

Option 2: Step-by-step Setup

Create a SolidStart project

  1. Create the new SolidStart project.
npm init solid@latest remult-solid-start-todo

Answer the questions as follows:

o  Is this a Solid-Start project?
|  Yes
o  Which template would you like to use?
|  basic
o  Use Typescript?
|  Yes
  1. Go to the created folder.
cd remult-solid-start-todo

Install Remult

npm i remult

Bootstrap Remult in the back-end

Remult is bootstrapped in a SolidStart using a catch all dynamic API route, that passes the handling of requests to an object created using the remultSolidStart function.

  1. Open your IDE.

  2. Create an api.ts file in the src folder with the following code - which will have the remult's api configuration.

    // src/api.ts
    import { remultSolidStart } from 'remult/remult-solid-start'
    export const api = remultSolidStart({})
  3. In the routes directory within the src folder, create an api directory. Inside the src/routes/api/ directory, craft a [...remult].ts file with the following code. This file functions as a catch all route for the SolidStart API route, effectively managing all incoming API requests.

    // src/routes/api/[...remult].ts
    import { api } from '../../api.js'
    export const { POST, PUT, DELETE, GET } = api

Enable TypeScript decorators

To enable TypeScript decorators:

  1. Install the required plugin

    npm i -D @babel/plugin-proposal-decorators @babel/plugin-transform-class-properties
  2. Add the following entry to the app.config.ts file to enable the use of decorators in the solid start app.

    // app.config.ts
    import { defineConfig } from "@solidjs/start/config"
    export default defineConfig({
      solid: {
        babel: {
          plugins: [
             ["@babel/plugin-proposal-decorators", { version: "legacy" }],

Run the app

Open a terminal and start the app.

npm run dev

The default SolidStart main screen should be displayed.

Cleanup SolidStart basic example

  1. Replace the content of src/app.tsx with the following code:

    import { MetaProvider, Title } from '@solidjs/meta'
    import { Router } from '@solidjs/router'
    import { FileRoutes } from '@solidjs/start/router'
    import { Suspense } from 'solid-js'
    import './app.css'
    export default function App() {
      return (
          root={(props) => (
              <Title>SolidStart - Basic</Title>
          <FileRoutes />

Remove SolidStart default styles

The SolidStart default styles won't fit our todo app. If you'd like a nice-looking app, replace the contents of src/app.css with this CSS file. Otherwise, you can simply delete the contents of src/app.css.

Setup completed

At this point, our starter project is up and running. We are now ready to move to the next step of the tutorial and start creating the task list app.
