An easy-to-follow guide so you can use Sublime Text to write javascript
Download Article
Javascript consoles are very handy for debugging and getting live results from your script. Although Sublime Text comes with build systems for many other scripting languages, it does not come with a built-in Javascript build system. Many sources will tell you to create a .html page with a link to the .js file, then use a web browser console to see the results of your code. This equates to constant window-switching and browser reloading; leading to frustration, heartache, and ultimately inefficiency. Fortunately, constructing your own Javascript build system for Sublime Text is quick and easy!
Things You Should Know
- Launch Sublime Text and build a new system.
- Replace the existing code with the code here, save it, then run it as a saved file to debug.
- Alternatively, open Node.js and build a new system in Sublime Text.
Steps
Setting Up
-
Launch Sublime Text.
- JSC is a command-line Javascript runner, cooked directly into Mac OS X. Because most Macs already contains everything you need to run the script, creating the build system in Sublime Text is incredibly easy.
- If you have a Windows computer, see the directions for Node.js below.
-
Go to Tools > Build System > New Build System in the top bar.Advertisement
-
Paste this code into the resulting new tab that Sublime Text opened. Replace anything else in it:
{ "cmd" : [ "/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc" , "$file" ], "selector" : "source.js" }
-
Save the file as JSC.sublime-build in the default "user" folder. Now you have created your build system!

Using the Console
-
Open the Javascript file that you want to run in Sublime Text.
-
Use debug() instead of console.log() in your script.
-
Go to Tools > Build System in the top bar and select JSC . This is the build system that you just created.
-
Build the Javascript file. Use either the shortcut ( Ctrl + B for Windows, and ⌘ Cmd + B for Mac), or choose Build from the Tools menu. A console will now appear in a pane at the bottom of the window, showing the results of your script!

Setting Up
-
Download the Node installer from the project's homepage and run it. Simply use the default settings.
- Node.js (Node) is a platform built to allow Javascript to run on a server. However, it can also be installed on your local computer, providing a relatively simple way to run Javascript and get the results without using a browser.
-
Go to Tools > Build System > New Build System in the top bar.
-
Paste this code into the resulting new tab that Sublime Text opened. Replace anything else in it:
{ "cmd" : [ "node" , "$file" ], "selector" : "source.js" }
- If you receive a "[Errno 2]" error, then you'll need to change node in the code above to the path where node is located. To do this, open terminal and run which node . This will print out the path to the node binary.
-
Save the file as node.sublime-build in the default "user" folder. Now you have created your build system!

Using the Console

-
Build the Javascript file. Use either the build shortcut ( Ctrl + B for Windows, and ⌘ Cmd + B for Mac), or choose Build from the Tools menu. A console will now appear in a pane at the bottom of the window, showing the results of your script!
