Answer 1

好吧，考虑到它只是json，而您想将其保存在本地，则可以将其另存为.json文件在磁盘上的某个位置，也许使用诸如fs之类的东西

You can use LocalStorage or SessionStorage to store your data in key value pairs.

If you want something more advanced I can recommend using localStorageDb wich is a database layer for those two.

An example:

var db = new localStorageDB("myDb", localStorage);
db.createTable("Persons", ["name", "surName", "birthDate"]);
db.insert("Persons", {name: "John", surName: "Doe", birthDate: new Date()});
db.commit()

Amplify.js will serve too with the advantage of being persistence agnostic, that is if LocalStorage is not supported it will fallback to another mechanism to store your data but lacks the database functionality.

If your database is large enough you should use IndexedDb or Web SQL. the main problem here beign compatibility. Check http://caniuse.com/indexeddb and http://caniuse.com/sql-storage

You can use this library https://github.com/yathit/ydn-db , it has support for schema generation, transactions, query support and client-server syncronization.
