# no-uninstalled-addons

<!-- RULE-CATEGORIES:START -->

**Included in these configurations**: <ul><li>recommended</li></ul>

<!-- RULE-CATEGORIES:END -->

## Rule Details

This rule checks if all addons in the storybook main.js file are properly listed in the root package.json of the npm project.

For instance, if the `@storybook/addon-links` is in the `.storybook/main.js` but is not listed in the `package.json` of the project, this rule will notify the user to add the addon to the package.json and install it.

As an important side note, this rule will check for the package.json in the same level of the .storybook folder.

Examples of **incorrect** code for this rule:

```js
// in .storybook/main.js
module.exports = {
addons: [
'@storybook/addon-links',
'@storybook/addon-essentials',
'@storybook/addon-interactions',
],
}

// package.json
{
"devDependencies": {
"@storybook/addon-links": "0.0.1",
"@storybook/addon-essentials": "0.0.1",
'
}
}
```
Examples of **correct** code for this rule:
```js
// in .storybook/main.js
module.exports = {
addons: [
'@storybook/addon-links',
'@storybook/addon-essentials',
'@storybook/addon-interactions',
],
}
// package.json
{
"devDependencies": {
"@storybook/addon-links": "0.0.1",
"@storybook/addon-essentials": "0.0.1",
"@storybook/addon-interactions": "0.0.1"
}
}
```
### Options
TODO: check if the package.json location should be an option.
## When Not To Use It
This rule is very handy to be used because if the user tries to start storybook but has forgotten to install the plugin, storybook will throw very weird errors that will give no clue to the user to what's going wrong. To prevent that, this rule should be always on.

/**
* Notes about this new feature
*
*
* The issues that this rule is trying to solve are:
* 1 - Addon is listed in the main.js file of Storybook, but is not installed
* 2 - Addon is listed in the main.js file of Storybook, but it contains a typo in its name
*
* Obs:
*
* addons: [
* // usual way to register addons
* '@storybook/addon-actions',
* {
*
* // alternative way to register addons
* name: '@storybook/addon-actions',
* options: {
* docs: false
* }
* ]
*
* Not every addon is starts with @storybook/addon or storybook-addon. But most of them do and this is a recommended way to register them.
*
* The solution:
*
* - When the addon is listed but not installed or there is a typo but it is not prefixed in the recommended way:
* The addon ${addonName} is not installed. Did you forget to install it?
*
* - When the addon is listed but has a typo and it is prefixed in the recommended way:
* The addon ${addonName} is not installed. Did you mean CORRECT_NAME instead of NAME_WITH_TYPO?
