Migrate Your Express Application to Fastify

• pino

  38 13,256 8.6 JavaScript

  🌲 super fast, all natural json logger

  

Fastify comes with Pino by default, but logging must be enabled for it to work:

• node-url-shortener

  1 2 1.5 JavaScript

Fastify offers many additional features that we couldn't cover in this series, so check out the Fastify official documentation to learn more. Also, you can find all the code samples we used in this GitHub repository.

• SurveyJS

  surveyjs.io sponsored

  Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  

• fastify-express

  9 226 5.5 JavaScript

  Express compatibility layer for Fastify

  

As mentioned in part 2 of this series, using the @fastify/express plugin is the quickest way to get your existing Express application working with Fastify. The plugin adds full Express compatibility to Fastify so that you can easily use any Express middleware — or even an entire Express application — with your Fastify instance, and it will just work with no changes required.

• point-of-view

  2 319 7.4 JavaScript

  Template rendering plugin for Fastify

  

Since we've migrated our only application route that renders templates, the above lines are no longer needed and can be safely deleted. But you now need to configure Fastify to render the Pug template through the @fastify/view plugin. It decorates the Reply interface with a method that we'll then use to render the template.

• ajv

  60 13,383 6.3 TypeScript

  The fastest JSON schema Validator. Supports JSON Schema draft-04/06/07/2019-09/2020-12 and JSON Type Definition (RFC8927)

  

Since Fastify supports schema validation with Ajv, the validate module is no longer required on the /shorten route, and we can specify the JSON schema directly on the route. The controllers for both routes will largely remain the same, except that the res parameter is renamed to reply as before:

• fastify-static

  2 405 7.6 JavaScript

  Plugin for serving static files as fast as possible

  

We can replace this middleware with the @fastify/static plugin, which you can install through the command below:

• fastify-helmet

  1 369 5.9 JavaScript

  Important security headers for Fastify

  

helmet -> @fastify/helmet.

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• fastify-cors

  5 376 7.3 JavaScript

  Fastify CORS

  

cors -> @fastify/cors.

• winston

  51 22,045 7.9 JavaScript

  A logger for just about everything.

  

Our Express application uses Winston and Morgan for logging HTTP requests.

• Jade

  38 21,527 0.0 JavaScript

  Pug – robust, elegant, feature rich template engine for Node.js

  

To illustrate the process of migrating from Express to Fastify, we have prepared a demo application. This application utilizes Express, Mongoose, and Pug to create a URL Shortener app as follows:

• telescope.nvim

  322 13,961 9.1 Lua

  Find, Filter, Preview, Pick. All lua, all the time.
