Use React's useEffect to optimize your application's performance.Don't miss a moment with The Replay, a curated newsletter from LogRocket.This means we must use a version of Node.js that has support for ES modules in order to use this package.įor our own code, we can show Node.js that all modules in our project are ES modules by adding 'type': 'module' in our package.json, or we can set the file extension of individual scripts to. ECMAScript Modules (ESM): uses export to export functions and objects and import to load them in another moduleĮxeca becomes a pure ESM package with its v6.0.0 release.CommonJS Modules (CJS): uses module.exports to export functions and objects and require() to load them in another module.Node.js supports two different module types: Using a pure ES module package in Node.js

Next, install the execa library: npm install execa Now, let’s create a new package.json file: npm init -yes Open up your terminal and create a new directory named tutorial, then change into that directory: mkdir tutorial It uses the popular cross-spawn package, which works around known issues with Node.js’ child_process.spawn method on Windows. Execa takes care of child process clean-up for us automatically, ensuring we don’t end up with “zombie” processes.Īnother benefit of using execa is that it brings its support for running child processes with Node.js on Windows. We probably don’t want child processes hanging around if the process that is executing our script ( node) dies for any reason.

This is convenient for readability on the command line, but not helpful in a scripting context, so execa automatically strips these new lines for us by default. It’s common for programs to include a new line at the end of their output. For example, if we’re passing a string with spaces or quotes, execa will take care of escaping them for us. If we need it, there is also an execaSync method for running commands synchronously.Įxeca also conveniently escapes and quotes any command arguments that we pass to it.

This means we can use async/await in our code instead of needing to create callback functions as we do with the asynchronous child_process module methods. There are several benefits that execa provides over the built-in Node.js child_process module.įirst, execa exposes a promise-based API.

Familiarity with the basics of JavaScript and Node.js.

We’ll also dive into the basics of error handling and process control, as well as look at the options we have for handling child process output.

In this article, we’re going to learn about the benefits of the execa library and how we can start using it. This popular library was created and is maintained by prolific open-source developer Sindre Sorhus, and it’s downloaded millions of times every week. The execa library provides a wrapper around the child_process module for ease of use. These commands can run any programs that are installed on the machine that we’re running the script on. It provides methods that allow us to write scripts that run a command in a child process. Node.js has a built-in child_process module. He's on Twitter at if you'd like to say hi.
