Generate a Node.js app that is packed with best practices AND simplicity in mind. Based off our repo Node.js best practices (96,100 stars)

A One Paragraph Overview

Although Node.js has great frameworks 💚, they were never meant to be dev & production ready immediately (e.g., no architecture layers, DB schemas, docker file, etc etc). Practica.js aims to bridge the gap. Based on your preferred framework, we generate example code that demonstrates a full Microservice flow, from API to DB, that is packed with good practices. For example, we include a battle-tested error handler, sanitized API response, hardened dockerfile, thoughtful 3-tier folder structure, great testing templates with DB, and more. This saves a great deal of time and can prevent painful mistakes. All decisions made are neatly and thoughtfully documented. We strive to keep things as simple and standard as possible and base our work on the popular guide: Node.js Best Practices

Super-Quick Setup

Run Practica.js from the Command Line

Run practica CLI and generate our default app (you can customize it using different flags):

npx @practica/create-node-app immediate --install-dependencies

✨ And you're done! That's it, the code's all been generated. Our default setup includes Fastify for the web layer, Sequelize for the data access and PostgreSQL

Prefer express and Prisma? Just pass the right flags to the CLI:

npx @practica/create-node-app immediate --install-dependencies --web-framework=express --orm=prisma

Prefer other DB? We use standard ORMs, read its docs and switch DB. This is your code, do whatever you like

Start the Project

cd {your chosen folder name}
npm install

Then choose whether to start the app:

npm run

or run the tests:

npm test

Pretty straightforward, right?

You just got a Node.js Monorepo solution with one example component/Microservice and multiple libraries. Based on this hardened solution you can build a robust application. The example component/Microservice is located under: {your chosen folder name}/services/order-service. This is where you'll find the API and a good spot to start your journey from

Next Steps

• ✅ Start coding. The code we generate is minimal by design and based on known libraries. This should help you get up to speed quickly.
• ✅ Read our 'coding with practica' guide
• ✅ Master it by reading our docs at https://practica.dev.

Our Philosophies and Unique Values

1. Best Practices on top of known Node.js frameworks

We don't re-invent the wheel. Rather, we use your favorite framework and empower it with structure and real examples. With a single command you can get an Express/Fastify-based codebase with many thoughtful best practices inside

2. Simplicity, how Node.js was intended

Keeping it simple, flat, and based on native Node/JS capabilities is part of this project's DNA. We believe that too many abstractions, high-complexity or fancy language features can quickly become a stumbling block for the team

To name a few examples, our code flow is flat with almost no level of indirection, no DI - it's just simple functions calling other functions. Although using TypeScript, almost no features are being used besides types, for modularization we simply use... Node.js modules

3. Supports many technologies and frameworks

Good Practices and Simplicity is the name of the game with Practica. There is no need to narrow our code to a specific framework or database. We aim to support the popular Node.js frameworks and data access approaches

Practices and Features

We apply dozens of practices and optimizations. You can opt in or out for most of these features using option flags on our CLI. The following table lists just a few examples out of the full list of features we provide.
