npm install sjlsjl - Simple JSON Loader
===
This tool responds to a simple need: load an object from a file containing its JSON representation,
or use a default JSON document if that file is not found.
Bash
npm install sjl
`Usage
Javascript
sjl(filePath, defaults, [options])
.then(...)
.catch(...);
`An example:
Javascript
var sjl = require('sjl');sjl('simple.json', {})
.then(function(data)
{
console.log('Loaded the following data: %s', JSON.stringify(data));
})
.catch(function(err)
{
console.log(err.toString());
});
`$3
Two options are provided, and autoreload, both are booleans.
The first one tells sjl whether or not to stay silent about files not being present and defaults being loaded instead.
The second one triggers the _autoreload_ feature [see below].
Reloading on file changes
When autoreload is set to true an event is thrown upon file contents changes,
making it possible to reload data automatically.
This feature can be used like this:
`Javascript
sjl('simple.json', {}, {'autoreload': true})
.then(function(data)
{
data.on('change', function(newData)
{
console.log('New data: %s', JSON.stringify(newData));
});
// Also generic errors are thrown:
data.on('error', function(err)
{
console.log('Could not auto-reload. %s', err);
});
});
