Use TypeScript compiler from node

Question

It\'s pretty easy to do this with coffee-script.

var coffee = require(\'coffee-script\');
coffee.compile(\"a = 1\");
//=> \'(function() {\\n  var a;\\n\\n  a

Since TypeScript's NPM module doesn't export any public interface, the only way to do this currently is to execute the tsc process.

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

var child = exec('tsc main.ts',
                function(error, stdout, stderr) {
                    console.log('stdout: ' + stdout);
                    console.log('stderr: ' + stderr);
                    if (error !== null) {
                      console.log('exec error: ' + error);
                    }
                });

An issue has been opened to request a public interface for the TypeScript module.
