In a previous article, I wrote about how to install Node.js® and, it’s companion, NPM on a Mac. In fact, concentrating on JavaScript as your language of choice offers the opportunity to master a single language while still being able to develop “full-stack” web applications. Web developers who work on the server-side are also flocking to JavaScript because of the efficiencies and speed offered by JavaScript’s event-driven, non-blocking nature. Front-end web developers use JavaScript to add user interface enhancements, add interactivity, and talk to back-end web services using AJAX. JavaScript is quickly becoming the go-to language for web developers.

Try our program out with a free seven-day trial today. It doesn't affect your scripts' behavior but can be helpful to create groups of scripts that are easier to identify by their prefixes.If you’re looking to take your JavaScript coding to another level, Treehouse offers unlimited courses in JavaScript (and many other subjects) starting at $25/month. One convention that you may have seen is using a prefix and a colon to group scripts, for example, 'build:prod'. It can be camelCase, kebab-case, or anything you prefer. In that case, choose a naming style and stick to it. Be consistent: You may need to use more than one word to name your script.If we can manage to keep our script names short, it'll be easier to remember them when we need them. Keep it short: If you take a look at Svelte's NPM Scripts, you'll notice that most script names are one word only.Here's my take on the subject, based on my research: There are no specific guidelines about how to name your scripts, but there are a few things we can keep in mind to make our scripts easier to pick up by other developers.

However, it doesn't add much value if your script is short and straightforward. This can be useful for especially complex scripts that would be hard to read in the package.json file. So to get the highest level of detail we could use npm run -ddd or npm run -loglevel silly. There are also short versions we can use to simplify the command: Now, if we want to get more detailed logs, we'll need to use a higher level than the default ('notice'). As we saw before, the -silent flag is the same as using -loglevel silent. We can explicitly define which loglevel we want to use when running a command, using -loglevel. Any logs of a higher level than the currently defined will be shown. The log level determines which logs will be displayed in the output.

There are different log levels: 'silent', 'error', 'warn', 'notice', 'http', 'timing', 'info', 'verbose', 'silly'. We saw how we can reduce logs using -silent, but what about getting even more detailed logs? Or something in between? ℹ️ If we don't want to get an error when the script doesn't exists, we can use -if-present instead: npm run -if-present. Maybe in a CI pipeline, you want your whole pipeline to keep running even when the test command fails. The -silent flag (short for -loglevel silent) can be helpful when you want to run a script that you know may fail, but you don't want it to throw an error. Use npm run -silent to reduce logs and to prevent the script from throwing an error. On failure, all logs are included in this file. The path to this file is provided at the end of the error message. Both can be useful for googling the error.Īnd if we need more information, we can always access the complete log file. When a script throws an error, we get a few other details, such as the error number errno and the code. To define an NPM script, all you need to do is set its name and write the script in the script property in your package.json file:Įnter fullscreen mode Exit fullscreen mode You can also use these scripts in your CI/CD pipeline to simplify tasks like build and generate test reports. Their goal is to provide a simple way to execute repetitive tasks, like: NPM Scripts are a set of built-in and custom scripts defined in the package.json file.

In this article, I'll share my research about how to take full advantage of NPM scripts. That's when I decided to learn everything I could about NPM scripts and write this article. I've been using NPM Scripts for years, but I wanted to pass a parameter to a script a few weeks ago and realized I didn't know how to do that. But do you know all you can do with NPM Scripts? You may have come across the scripts property in the package.json file and even write some scripts yourself.
