Node.js

The most commonly used node.js driver is the Node Tarantool driver. It is not supplied as part of the Tarantool repository; it must be installed separately. The most common way to install it is with npm. For example, on Ubuntu, the installation could look like this after npm has been installed:

$ npm install tarantool-driver --global

Here is a complete node.js program that inserts [99999,'BB'] into space[999] via the node.js API. Before trying to run, check that the server instance is listening at localhost:3301 and that the space examples exists, as described earlier. To run, paste the code into a file named example.rs and say node example.rs. The program will connect using an application-specific definition of the space. The program will open a socket connection with the Tarantool instance at localhost:3301, then send an INSERT request, then — if all is well — end after saying “Insert succeeded”. If Tarantool is not running on localhost with listen port = 3301, the program will print “Connect failed”. If the ‘guest’ user does not have authorization to connect, the program will print “Auth failed”. If the insert request fails for any reason, for example because the tuple already exists, the program will print “Insert failed”.

var TarantoolConnection = require('tarantool-driver');
var conn = new TarantoolConnection({port: 3301});
var insertTuple = [99999, "BB"];
conn.connect().then(function() {
    conn.auth("guest", "").then(function() {
        conn.insert(999, insertTuple).then(function() {
            console.log("Insert succeeded");
            process.exit(0);
    }, function(e) { console.log("Insert failed");  process.exit(1); });
    }, function(e) { console.log("Auth failed");    process.exit(1); });
    }, function(e) { console.log("Connect failed"); process.exit(1); });

The example program only shows one request and does not show all that’s necessary for good practice. For that, please see The node.js driver repository.
