title: Expand Your Project with External Packages from npm
challengeType: 2
---
## Description
One of the biggest reasons to use a package manager is their powerful dependency management. Instead of manually having to make sure that you get all dependencies whenever you set up a project on a new computer, npm automatically installs everything for you. But how can npm know exactly what your project needs? Meet the dependencies-section of your package.json.
In the dependencies-section, packages your project require are stored using the following format:
"dependencies": {
"package-name": "version",
"express": "4.14.0"
}
Instructions
Add version 2.14.0 of the package moment to the dependencies-field of your package.json
Moment is a handy library for working with time and dates.
## Instructions
## Tests
```yml
tests:
- text: '"dependencies" should include "moment"'
testString: 'getUserInput => $.get(getUserInput(''url'') + ''/_api/package.json'').then(data => { var packJson = JSON.parse(data); assert.property(packJson.dependencies, ''moment'', ''"dependencies" does not include "moment"''); }, xhr => { throw new Error(xhr.responseText); })'
- text: '"moment" version should be "2.14.0"'
testString: 'getUserInput => $.get(getUserInput(''url'') + ''/_api/package.json'').then(data => { var packJson = JSON.parse(data); assert.match(packJson.dependencies.moment, /^[\^\~]?2\.14\.0/, ''Wrong version of "moment" installed. It should be 2.14.0''); }, xhr => { throw new Error(xhr.responseText); })'
