Run Node.js Express Application from TextMate

I tried a lot of existing solutions but I could not use one, so I created a new script for it.

Setup

Open Textmate > Preferences > Advanced > Shell Variables and add your node path to the PATH variable (with homebrew append :/usr/local/bin).

Now, let’s create a new command. Open Bundles > Bundle Editor > Edit Commands and create a New Bundle (name it whatever you want; I named it JavaScript With Node). Create a new command under your new bundle (name of my command is Run With Node) with the following code:

#!/usr/bin/env node

var sys = require("sys"),
spawn = require('child_process').spawn;

/*
* htmlEntities function is from Chris Coyier
* URL: http://css-tricks.com/snippets/javascript/htmlentities-for-javascript/
*/
function htmlEntities(str) {
return String(str).replace(/&/g, '&')
                .replace(/</g, '&lt;')
                .replace(/>/g, '&gt;')
                .replace(/"/g, '&quot;');
}

(function(path, file) {
console.log("<div style='color: green'>Run "
        + path + "/" + file
        + "</div>");
var app = spawn("node", [path + "/" + file], { cwd: path });
app.stdout.on('data', function(data) {
console.log("<div>"
          + htmlEntities(data)
          + "</div>");
});
app.stderr.on('data', function(data) {
console.log("<div style='color: red'>"
          + htmlEntities(data)
          + "</div>");
});
app.on('exit', function(code) {
console.log('App exited with code ' + code);
});
})(process.env.TM_DIRECTORY, 'app.js');

Parameters

Save:   Current File
Input:  Entire Document
Output: Show as HTML

Optional

Activation:     Key Equivalent with ⌘R (Command + R)
Scope Selector: source.js

Additional

If you don’t want to create a script for one file (instead of the entire Express application) then use this code (e.g. Run File With Node):

#!/usr/bin/env node

var sys = require("sys"),
spawn = require('child_process').spawn;

/*
* htmlEntities function is from Chris Coyier
* URL: http://css-tricks.com/snippets/javascript/htmlentities-for-javascript/
*/
function htmlEntities(str) {
return String(str).replace(/&/g, '&amp;')
                .replace(/</g, '&lt;')
                .replace(/>/g, '&gt;')
                .replace(/"/g, '&quot;');
}

(function(path, file) {
console.log("<div style='color: green'>Run "
        + file
        + "</div>");
var app = spawn("node", [file], { cwd: path });
app.stdout.on('data', function(data) {
console.log("<div>"
          + htmlEntities(data)
          + "</div>");
});
app.stderr.on('data', function(data) {
console.log("<div style='color: red'>"
          + htmlEntities(data)
          + "</div>");
});
app.on('exit', function(code) {
console.log('App exited with code ' + code);
});
})(process.env.TM_DIRECTORY, process.env.TM_FILEPATH);
