# --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 file.
|
|
|
|
In this section, packages your project requires are stored using the following format:
|
|
|
|
```json
|
|
"dependencies": {
|
|
"package-name": "version",
|
|
"express": "4.14.0"
|
|
}
|
|
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Add version "1.1.0" of the `@freecodecamp/example` package to the `dependencies` field of your `package.json` file.
|
|
|
|
**Note:** `@freecodecamp/example` is a faux package used as a learning tool.
|
|
|
|
# --hints--
|
|
|
|
`"dependencies"` should include `"@freecodecamp/example"`.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert.property(
|
|
packJson.dependencies,
|
|
'@freecodecamp/example',
|
|
'"dependencies" does not include "@freecodecamp/example"'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
`"@freecodecamp/example"` version should be `"1.1.0"`.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert.match(
|
|
packJson.dependencies["@freecodecamp/example"],
|
|
/^[\^\~]?1\.1\.0/,
|
|
'Wrong version of "@freecodecamp/example" installed. It should be 1.1.0'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
