Node.js - Parse simple JSON object and access keys and values

If request.body is already being parsed as JSON, you can just access the data as a JavaScript object; for example,

request.body.store_config

Otherwise, you'll need to parse it with JSON.parse:

parsedBody = JSON.parse(request.body);

Since store_config is an array, you can iterate over it:

request.body.store_config.forEach(function(item, index) {  // `item` is the next item in the array  // `index` is the numeric position in the array, e.g. `array[index] == item`});

If you need to do asynchronous processing on each item in the array, and need to know when it's done, I recommend you take a look at an async helper library like async--in particular, async.forEach may be useful for you:

async.forEach(request.body.store_config, function(item, callback) {  someAsyncFunction(item, callback);}, function(err){  // if any of the async callbacks produced an error, err would equal that error});

I talk a little bit about asynchronous processing with the async library in this screencast.

Something like this:

config = JSON.parse(jsonString);for(var i = 0; i < config.store_config.length; ++i) {   for(key in config.store_config[i]) {      yourAsyncFunction.call(this, key, config.store_config[i][key]);   }}

To convert this sting to an actual object, use JSON.parse. You can iterate though Javascript objects like you would with an array.

config = JSON.parse(string).store_config[0]foreach (var key in config) {    value = config[key]}
