As Gecko is moving toward more Rust code, the cases where Rust and C code interoperate will become more common.

This document is an attempt to ease the learning curve for engineers facing it for the first time. It assumes no prior experience with cross-language C interfaces (called FFI).

It also assumes that Rust code is already built into Gecko. If you need help with that, read Introducing Rust code in Firefox.

Go development environment on Windows with MSYS2

Normally, it is sufficient to grab the Go MSI installer from the website in order to set up the toolchain. However, some packages that provide Go wrappers for C libraries rely on cgo tool, which in turn, needs the GCC toolchain in order to build the glue code. Also, 3rd-party dependencies are usually hosted on services like GitHub, thus Git is also needed. This mini-guide illustrates how to setup a convenient development environment on Windows using MSYS2.

Using @react-pdf/renderer v3.0.1 with React 18

Introduction

When I tried to use the @react-pdf/renderer package (version 3.0.1) with a React 18 app, two problems arose. In this article, I'll describe those problems and tell you how I solved them.

Update: Here's a video demonstration of the problems and solution described in this article: https://youtu.be/YZP5r7Uy_bU

Problem 1: Dependency Conflict

// Types for the result object with discriminated union
type Success<T> = {
  data: T;
  error: null;
};

type Failure<E> = {
  data: null;
  error: E;
};
