How do I execute the mongodump command programmatically from node.js?

mongodb, node.js

Solution

Try using `child_process.spawn(command, args)`:

var spawn = require('child_process').spawn;

// ...
  collection.insert(docs, {safe:true}, function(err, result) {
    var args = ['--db', 'mydb', '--collection', 'test']
      , mongodump = spawn('/usr/local/bin/mongodump', args);
    mongodump.stdout.on('data', function (data) {
      console.log('stdout: ' + data);
    });
    mongodump.stderr.on('data', function (data) {
      console.log('stderr: ' + data);
    });
    mongodump.on('exit', function (code) {
      console.log('mongodump exited with code ' + code);
    });
  });
// ...

Problem

What is the best way to execute mongodb admin/console commands programmatically from node.js? Specifically, I would like to export a mongodb collection using mongodump after performing a series of inserts. Something like this: ``` // requires and initializing stuff left out for brevity db.open(function(err, db) { if(!err) { db.collection('test', function(err, collection) { var docs = [{'hello':'doc1'}, {'hello':'doc2'}, {'hello':'doc3'}]; collection.insert(docs, {safe:true}, function(err, result) { // Execute mongodump in this callback??? }); }); } }); ```
