Saving Backbone.js Collection as Text File on HDD & Re-importing Data

Question

Saving Backbone.js Collection as Text File on HDD & Re-importing Data

After experimenting with Backbone.js for a while, I've relied on localStorage to store most of my app data. However, I now want to explore the possibility of exporting my collection to plain text for easy backup purposes. Essentially, I envision a feature where I can export the data as plain text, view it in an HTML textbox, and then import it back by pasting into another textbox to recreate the collection.

Is this kind of functionality possible? Any suggestions on how to make it happen? My initial thought was to export the data in JSON format and then import it back that way. Would that be a feasible approach?

p.s. While there is no actual code provided here, I would greatly appreciate any insights or ideas on how to achieve this feature.

To serialize the collection, one can utilize the toJSON method. (Referenced as a primary use by Backbone.js). To convert the JSON object to a string, simply use JSON.stringify.

var json = myCollection.toJSON();
var serializedString = JSON.stringify(json);

For restoring the collection, follow these steps:

Use JSON.parse to transform the raw string into a JSON object
Utilize collection.reset to convert the JSON object back into a collection

Check out this working example.

// Setting up a test collection
var collection = new Backbone.Collection();
collection.add(new Backbone.Model({ hello: "world" }));

// Serializing it into a string
var json = collection.toJSON();
var serialized = JSON.stringify(json);
console.log(serialized);

// Bringing it back
var json2 = JSON.parse(serialized);
var collection2 = new Backbone.Collection();
var restored = collection2.reset(json2);

// Checking if it worked
console.log(restored.at(0).get("hello"));
