How to read a properties file in javascript from project directory?
I'm building a Chrome Packaged App. I want to put the script configuration if a config file in a resource directory and on startup want to read that by Javascript.
For example
- Project
- WebContent
- index.html
- manifest.json
- main.js
- resource
- config.properties
- WebContent
Here I want main.js to load config.properties file in the beginning and get key-value pairs.
Have anyone done something like this?
Answer
There is a super simple way to do this, along the lines of sowbug's answer, but which doesn't need any XHR or file reading.
Step 1. Create resource/config.js like so:
gOptions = {
// This can have nested stuff, arrays, etc.
color: 'red',
size: 'big',
enabled: true,
count: 5
}
Step 2. Include this file in your index.html:
<!doctype html>
<head>
<script src="resource/config.js"></script>
...
Step 3. Access your options directly from your main.js (or anywhere):
...
if (gOptions.enabled) {
for (var i = 0; i < gOptions.count; i++) {
console.log(gOptions.color);
}
}
...
