What are the latest updates and new features in Jeasx?

Welcome to the news section of Jeasx. Here we are going to post updates about new features, bug fixes, and general information about the project. We are proud to announce that Jeasx is rock stable and ready for production. We are committed to keep the project as small as possible and focus on the core. Future updates are likely updates for 3rd party dependencies like fastify, esbuild and pm2.

Release History

2025-01-06 - Jeasx 1.2.2 released

🎉 This release is just a minor dependency update: fastify@5.2.1, fastify/cookie@11.0.2 and types/node@22.10.5.

2024-12-12 - Jeasx 1.2.1 released

🎉 This release fixes a bug introduced by the recently introduced route caching feature: if a guard returned different response types (e.g. JSX code for a forbidden route, otherwise props for the guarded routes), the guarded routes weren't resolved anymore.

2024-12-07 - Jeasx 1.2.0 released

🎉 This release brings a major performance boost (about 2-5 times faster in benchmarks) by introducing runtime caches for resolved routes and loaded JavaScript modules. The caches are only used in production and won't interfere with your development workflow. This change was triggered by a PR submitted by Bryce, Kudos to him for bringing this topic onto the radar.

It also features an update to jsx-async-runtime which provides more accurate and also deprecated typings for HTML tags and attributes according to the fantastic HTML reference from the Mozilla Development Network.

Added two new environment variables (FASTIFY_DISABLE_REQUEST_LOGGING and FASTIFY_TRUST_PROXY) to give you more control over how Jeasx should behave in different environments.

2024-12-01 - Jeasx 1.1.0 released

🎉 Migrated from dotenv to dotenv-flow, so you can use NODE_ENV-specific .env* files (like .env.development) to configure different environments for production and development. This is useful to disable caching headers (e.g. via FASTIFY_STATIC_HEADERS) in development, as Jeasx applies FASTIFY_STATIC_HEADERS in development from now on for a more consistent developer expierence. See updated .env-files in the quickstart-project for an example how to disable caching in development. This is only needed if you have configured FASTIFY_STATIC_HEADERS for your existing projects.

Bumped default environment variable ESBUILD_BROWSER_TARGET to more recent browser versions (e.g. chrome126, edge126, firefox128, safari17). If you want to stick with older versions, you can override it via the environment. Learn more about possible values at the esbuild website.

Updated jsx-async-runtime which fixes a bug in escapeEntities which escaped existing & two times. This release also removes the deprecated renderToString function. Simply replace it with jsxToString.

The default host is now :: which binds to all available network interfaces (e.g. IPv6). You can change it via the HOST environment variable (e.g. HOST=0.0.0.0 for the old behaviour). The change is especially useful to connect to Jeasx via private networking on hosting platforms like Railway.

2024-11-15 - Jeasx 1.0.2 released

🎉 Disabled cache-control for fastify-static, so proper Cache-Control response header could be applied via the environment variable FASTIFY_STATIC_HEADERS. Have a look at the env-file in the quickstart project for an example.

2024-11-01 - Jeasx 1.0.1 released

🎉 This version brings official support for Node 22. Also dependencies were updated to latest versions of fastify@5.0.1, fastify/static@8.0.2 and fastify/cookie@11.0.1. Added new examples for template fragments in combination with HTMX and image optimization with sharp.

2024-10-04 - Jeasx 1.0.0 released

It's finally here! Jeasx 1.0.0 is ready for production. We are proud to announce that the framework has reached feature completeness and is now ready for the masses. Lots of hours of work have been put into this project to make sure you have the best experience possible.

2024-09-23 - Jeasx 0.15.2 released

Updates to all @fastify-plugins and esbuild@0.24.0.

2024-09-21 - Jeasx 0.15.1 released

Decorate the Fastify request object with "path" property, so you can easily access the route path without query parameters via request.path. This solves 99% of all use-cases for recently removed @fastity/url-data.

2024-09-20 - Jeasx 0.15.0 released

This release comes with Fastify 5. It also removes @fastify/url-data and @fastify/accepts as dependencies, therefore your code might break. The reason behind this removal is to depend on less dependencies in the long run which makes maintenance of the core easier.

If you rely on either accepts or url-data, you must provide appropriate changes in userland code. For @fastify/url-data I would recommend to use fast-uri and for @fastify/accepts jshttp/accepts for parsing accept-header if needed.

Please note: there were some intermediate releases since the past proper release which shouldn't be used (and are mostly unpublished from npm).

2024-08-21 - Jeasx 0.11.2 released

Added simple Dockerfile to quickstart template. Dependency updates: esbuild@0.23.1, @fastify/cookie@9.4.0, @types/node@20.16.1

2024-07-27 - Jeasx 0.11.1 released

Performance optimization: if response is string or buffer, break evaluation loop early. This allows to build caches for pages and binary assets in userland.

2024-07-26 - Jeasx 0.11.0 released

Updated to jsx-async-runtime@0.5.0 which allows to override jsxToString from jsx-async-runtime to intercept / modify / replace JSX components via this context. Have a look at the example to see how it works.

2024-07-19 - Jeasx 0.10.1 released

Breaking change: removed @fastify/request-context in favor of the recently introduced this context. Changing your code should be straightforward. This change decouples userland code from Fastify. Additionally code for Jeasx and jsx-async-runtime is provided unminified, so debugging and testing is far easier now.

2024-07-12 - Jeasx 0.9.1 released

Updated to jsx-async-runtime@0.4.1 which fixes a problem when running tests with Vitest.

2024-07-10 - Jeasx 0.9.0 released

Updated to jsx-async-runtime@0.4.0 which allows to use 'this' as context object to avoid prop drilling. Have a look at the demo to see how things work.

2024-07-05 - Jeasx 0.8.0 released

Updated to jsx-async-runtime@0.3.0 (deprecated renderToString in favor of jsxToString)

2024-07-03 - Jeasx 0.7.6 released

Updated to esbuild@0.23.0

2024-07-01 - Jeasx 0.7.5 released

Updated to fastify@4.28.1, esbuild@0.22.0, pm2@5.4.1

2024-05-28 - Jeasx 0.7.4 released

Updated to esbuild@0.21.4, pm2@5.4.0

2024-05-17 - Jeasx 0.7.3 released

Updated to esbuild@0.21.3, @types/node@20.12.12

2024-05-08 - Jeasx 0.7.2 released

Updated to fastify@4.27.0, esbuild@0.21.1, @fastify/static@7.0.4

2024-05-07 - Jeasx 0.7.1 released

Updated esbuild to 0.21.0.

2024-04-27 - Jeasx 0.7.0 released

This release introduces a new feature that allows you to post-process the resulting payloads, such as prettifying the HTML output. You can now set up a response handler, for example, in a guard. The response handler takes the resulting payload as a parameter and returns the modified payload.

import * as prettier from "prettier";
...
export default function RootGuard({ request, reply }) {
  this.response = async (payload) => {
    return typeof payload === "string" &&
      String(reply.getHeader("content-type")).startsWith("text/html")
      ? await prettier.format(payload, { parser: "html" })
      : payload;
  };
}

Shame on me...

I have recently started writing news as we approach the 1.0 release. But you can study the changelog at GitHub to see what has happend in the past.
