create-originate-app

This project is designed to make it easy to set up a Nextjs/Nest/TypeORM app! Let's get you oriented with what's here and how to use it.

Features

Full-stack framework

An API backend powered by NestJS provides a fully-featured GraphQL and REST framework, and a database interface to PostgreSQL. The frontend is powered by Next.js which provides server-side rendering, static page generation, routing, and a number of other useful features.

Start the app with yarn dev:backend and yarn dev:frontend

ℹ️ Why don't we have one script that runs both servers? The backend dev script clears the terminal when files change, and mixing output from both scripts makes it hard to tell what is going on. But if you want to run both servers in one terminal you can use this command (with a single &): yarn dev:backend & yarn dev:frontend

For some more details on how NestJS and Next.js work, and how they fit together see the developing docs.

Database out-of-the-box

When you run yarn dev:backend a postgres database automatically starts up in a docker container. Running backend end-to-end tests with yarn workspace @myapp/backend test:e2e --watch creates a fresh, temporary database for each run of each test file. The dev database is persistent, but can be recreated from scratch at any time by running yarn workspace @myapp/backend db:destroy. Test database containers are deleted once tests complete.

Rapid development cycle

The app database schema is inferred from code. In development mode when you make a change to your database code, the schema of the dev database updates instantly to match. When you're ready to commit changes generate a migration to run in production with yarn workspace @myapp/backend db:migration:generate -n MyMigration.

ℹ️ After generation, migrations can be modified by hand to add custom indexes, to massage data, etc.

The app GraphQL schema is also inferred from code, and also updates instantly when you make code changes.

The frontend implements fast refresh. When you make changes to code, changed React components are updated in the browser without reloading the entire page, and without losing local state.

End-to-end type safety

React code fetches data from the API via GraphQL queries embedded in TypeScript code. A TypeScript compiler plugin provides IDE completions, error checking, and type display as you write queries. Automatically-generated TypeScript interfaces allow TypeScript to infer the exact type of result data for each query, and to infer types of variables required by each query. Changes to the API will produce type errors if they introduce incompatibility with the frontend implementation, and vice versa.

ℹ️ GraphQL queries do require a type assertion to make type inference work. It looks like as import(@graphql-typed-document-node/core).TypedDocumentNode<... Don't bother writing those yourself - run yarn lint --fix to have the appropriate type assertion put in automatically.

Server-side rendering, and static generation

Server-side rendering is easy with Next.js. Public landing pages, and other pages that do not update frequently can be pre-rendered (static generation), or can be rendered on-demand server-side. That provides fast page load times for cases where minimizing bounce rates is important without requiring a separate system for static pages. Most of the time you can write React code as usual without thinking about server-side rendering. But when you need it, the tools are there.

ℹ️ Server-side rendering pairs very nicely with a CDN!

CI Workflows

A Github Actions workflow is included to run tests and sanity checks. If you use Github then your CI is ready to go out of the box.

Ready to deploy

TODO: We hope to provide deployment scripts that will work out-of-the-box with minimal manual setup.

Expandable with features for your use case

The NestJS module system in particular makes it possible to extract pieces of app behavior into reusable components. We want to set up modules for features like authentication with different providers, CMS integration, cloud file storage with different providers, etc. And because NestJS is a well-known framework you may be able to find the feature you want available on NPM, ready to drop into your app.

Getting started

Prerequisites

Make sure you have:

• Node
• Yarn
• Docker

We recommended the latest Node LTS release, which at the time of this writing is v14.

Docker must be set up so that you can run it without using sudo, and the Docker executable has to be called docker.

1. Generate an app

Run this command,

$ npx create-originate-app myapp

2. Start the app

Start the backend and frontend in separate terminals with these commands:

$ yarn dev:backend

$ yarn dev:frontend

You can access the interactive GraphQL playground on the backend server at http://localhost:4000/graphql, and the frontend at http://localhost:3000/
