Remix Template

With :

• Remix (obviously)
• Tailwind CSS
• Prisma (SQLite by default)
• Zod (To easily validate and format form errors)
• qs (To parse complex form data)
• SuperJSON (To send complex data through loaders)
• Remix Utils

Before you start

You should check out the demo app to learn what you can achieve with this template (read here).

Then you should delete these :

• Then entire /app/features/demo directory
• The /app/routes/demo.tsx file
• The demo() function in /prisma/seed.ts
• The two Demo models in /prisma/schema.prisma

Don't forget to add a .env file at the root of the project and declare a DATABASE_URL too.

You should also update meta() function and the manifest.json with you application name.

Features

A quick summary of the key features :

• Data
  • Send and receive complex objects with dates and more through your loader
  • Ensure your loader and action returns the same thing as expected between client and server
  • Easily paginate lists of data, directly in your loader with a page number the query param
  • Store and access your data easily with Prisma
• Forms
  • Send arrays, objects and arrays of objects from your forms with qs
  • Get a properly typed and deserialized object of your form in your action with a single function call
  • Validate this object, and get back nice and precise errors with Zod (with the same function call)
  • Easily and nicely display those errors to the user
  • Get what the action of a multi-action route form in one line (example: create or delete)
  • Ensure this action is the one sent by your form client-side

Utilitary functions and components

A lot of utils functions and hooks are already available with Remix Utils, this template adds a bunch more like :

• parseFormData() and safeParseFormData(), using qs and zod to powerfully parse your form data. It allows to :

  • Parse primitive directly (Numbers, dates, null/undefined, arrays, objects...)
  • Provide a zod validator to ensure the form is correct (compatible with <FormField/>)

  Just throw your request and your zod validator inside parseFormData(), catch a potential error and return error.format(). Now you can simply wrap your inputs in <FormField error={actionResult.error?.myField}/> to nicely display your zod error messages !

  You can send objects and arrays from a form by simply appending [] or [key] to the fields name :

   <input type="text" name="title" />
   <input type="number" name="order" />
   <input type="text" name="user[firstName]" />
   <input type="text" name="user[lastName]" />
   <input type="date" name="dates[]" />
   <input type="date" name="dates[]" />
   <input type="date" name="dates[]" />

  becomes :

  {
      title: 'My project',
      order: 5,
      user: {
         firstName: 'Quentin',
         lastName: 'Widlocher',
      },
      dates: [
         Date Wed Feb 23 2022 00:00:00,
         Date Tue Jul 21 2022 00:00:00,
         Date Thu Mar 01 2022 00:00:00,
      ],
  }

• useCurrentRoute(), to simply get the name of the current route client-side

• useNestedHandleValue(), to access previously loaded data from parent routes client-side.

• getFormAction(), to quickly extract the _action field from a form, and ensure it's correctly typed. This field is usually used to have a single route with multiple actions. You can also use this type in the client to ensure the form provides the right type

• <FormField/> and <ErrorMessage/>, to display a form field with a label, and automatically display ZodFormattedErrors from your validator.

• paginateLoader(), to quickly paginate a list, coming from any source of data. It uses a ?p=1 query parameter.

A Prisma ORM, ready to use

The template comes with Prisma.

You can access the Prisma client by importing db from ~/utils/db.ts.
This script allow reloading the Remix server without re-creating a new database connection each time.

You can seed your Prisma database by updating the seed() function in /prisma/seed.ts

Tailwind CSS

The template uses PostCSS to include

• Tailwind
• Tailwind Form Reset plugin
• Support for CSS Nesting (because it's so much easier to write custom CSS like that)
• A Prettier plugin that automatically reorder your Tailwind classes.

CSS is compiled from /styles to /app/styles.
Don't write css inside /app/styles or else it will be removed!

Ready to be a PWA

This template provide a manifest.json and a service worker (sw.js) to cache requests to built files.

A demo "app"

Everything mentionned above can be seen in the /app/features/demo directory. It's heavily commented so you should definitely have a look to see how I recommend using this template.

To view this demo :

1. Add this line to a .env file at the root of the project :
   • DATABASE_URL=file:./demo-db.sqlite?mode=memory&cache=shared
2. Run yarn && yarn prisma migrate dev to build the database
3. Run yarn dev to launch the app
4. Access the demo on localhost:3000/demo

This demo is loosely based on Bulletproof React. This is simply how I prefer to organize my code but feel free to do as you please.
