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:
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/
