A common use of JSON is to exchange data to/from a web server.

When sending data to a web server, the data has to be a string.

In this section, you will learn how to interact with SQLite databases from a Node.js application using the sqlite3 module. After the tutorial, you will know how to open a database connection and perform common database operations such as select, insert, update, and delete.In addition, you will learn how to execute SQL statements in serialized mode or in parallel mode.

There are some top-level similarities to consider when deciding which back-end technology is best for you. Interpreted languages.

Convert a JavaScript object into a string with JSON.stringify().

Stringify a JavaScript Object

Imagine we have this object in JavaScript:

var obj = { name: \'John\', age: 30, city: \'New York\' };

Use the JavaScript function JSON.stringify() to convert it into a string.

The result will be a string following the JSON notation.

myJSON is now a string, and ready to be sent to a server:

Example

var obj = { name: \'John\', age: 30, city: \'New York\' };
var myJSON = JSON.stringify(obj);
document.getElementById(\'demo\').innerHTML = myJSON;

Stringify a JavaScript Array

It is also possible to stringify JavaScript arrays:

Imagine we have this array in JavaScript:

Use the JavaScript function JSON.stringify() to convert it into a string.

The result will be a string following the JSON notation.

myJSON is now a string, and ready to be sent to a server:

Example

var arr = [ \'John\', \'Peter\', \'Sally\', \'Jane\' ];
var myJSON = JSON.stringify(arr);
document.getElementById(\'demo\').innerHTML = myJSON;

Exceptions

Stringify Dates

In JSON, date objects are not allowed. The JSON.stringify() function will convert any dates into strings.

Example

var obj = { name: \'John\', today: new Date(), city : \'New York\' };
var myJSON = JSON.stringify(obj);
document.getElementById(\'demo\').innerHTML = myJSON;

Try it Yourself »

You can convert the string back into a date object at the receiver.

Stringify Functions

In JSON, functions are not allowed as object values.

The JSON.stringify() function will remove any functions from a JavaScript object, both the key and the value:

Example

var obj = { name: \'John\', age: function () {return 30;}, city: \'New York\'};
var myJSON = JSON.stringify(obj);
document.getElementById(\'demo\').innerHTML = myJSON;

Try it Yourself »

This can be omitted if you convert your functions into strings before running the JSON.stringify() function.

Example

var obj = { name: \'John\', age: function () {return 30;}, city: \'New York\' };
obj.age = obj.age.toString();
var myJSON = JSON.stringify(obj);
document.getElementById(\'demo\').innerHTML = myJSON;

Try it Yourself »

You should avoid using functions in JSON, the functions will lose their scope, and you would have to use eval() to convert them back into functions.

Browser Support

The JSON.stringify() function is included in all major browsers and in the latest ECMAScript (JavaScript) standard.

The numbers in the table below specifies the first browser version that fully supports the JSON.stringify() function:

A simple node utility to serialize execution of asynchronous functions.

What does it do?

Asynchrony in nodejs is great, except that it makes your code looks horrible because of all the callbacks. If you use synchronous functions, which give you good-looking, easy-to-read code, they will block the thread and make your server not responsive.

Here\'s serailize to the rescue! serialize converts your asynchronous functions into serialized versions. Serialized functions are executed one after another, without explicitly chaining them with callback functions. serialize does NOT execute the function synchronously (block the thread), it just serialize the execution of asynchronous functions. So that it makes the code looks synchronous, but it is actually ascynhronous underneath.

How to use it?

To create a serialized version of an asynchronous function, call serialize with it. For example, if you want to make serialized versions of fs.writeFile and fs.mkdir, you do:

This service manual contains complete information included in original factory repair manual We guarantee that our manual contains circuit diagrams.Service manuals usually include printed circuit boards, block diagrams, exploded views, assembly instructions and parts catalog.

Then, you can use fs.mkdir and fs.writeFile like they are synchronous functions:

These function will be executed one after another, but they will not block the thread as their synchronous versions do. The callback will be invoked after the last call completes.

If you want to restore fs.writeFile and fs.mkdir to their original version, just do:

What if an error happens?

If an error happens, the error will be passed to the corresponding callback function, and the execution of all serialized calls after it will be aborted. If an error happens in a function call that does not have a callback, the error will be passed down to the first call that has a callback function.For example, if the fs.mkdir(\'new\') call in the above code throws an error, because there\'s no callback attached to that call, the error will be passed down to the callback of fs.writeFile(..). And, of course, fs.mkdir(\'new/folder\') and fs.writeFile(..) won\'t be executed because an error occurred before them.

What\'s more to it?

If you want to serialize calls to file system, and serialize calls to database, but allow calls to file system and calls to database to happen concurrently, how to do it?You can serialize different functions into different queues. Functions belong to the same queue will be executed in serial, but functions between different queues can run concurrently.To serialize a function to a queue other than the default queue, give a queue name as the second argument of serialize:

Is any function serializable?

Current version of serialize can only serialize a function that satisfies the following conditions:

1. It accepts a callback function, and invokes the callback when it is done;
2. If an error occurs, it must invoke callback with the error as the first argument; the error must be an instance of Error.

Note: Future version of serialize may be able to serialize a function that emits end and error events.
