In this lesson we will learn how to create a boot script.

We will use a boot script to create or update a predefined admin user, and give that user an Access Token. That way we don't have to log in to the API each time we want to use it as an authenticated user.

Hi, tnx for great tutorial! I have one question, after I require bluebird I'm getting a new error:

Unhandled rejection TypeError: cb is not a function at /Projects/playground/egghead/loopback-tutorial/node_modules/loopback-boot/lib/executor.js:318:34 at tryCatcher (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/util.js:16:23) at Promise._settlePromiseFromHandler (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/promise.js:512:31) at Promise._settlePromise (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/promise.js:569:18) at Promise._fulfillPromises (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/promise.js:668:14) at Promise._settlePromises (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/promise.js:694:18) at Async._drainQueue (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/async.js:133:16) at Async._drainQueues (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/async.js:143:10) at Immediate.Async.drainQueues (/Projects/playground/egghead/loopback-tutorial/node_modules/bluebird/js/release/async.js:17:14) at runCallback (timers.js:637:20) at tryOnImmediate (timers.js:610:5) at processImmediate [as _immediateCallback] (timers.js:582:5)

Somebody maybe know how to solve this? Tnx :)

Hi, I've replaced .asCallback with regular .then and it worked. This way I don't need to require bluebird
