19 | ### Features
|
20 |
|
21 | * Tells you what's out of date.
|
22 | * Provides a link to the package's documentation so you can decide if you want the update.
|
23 | * Kindly informs you if a dependency is not being used in your code.
|
24 | * Works on your globally installed packages too, via `-g`.
|
25 | * **Interactive Update** for less typing and fewer typos, via `-u`.
|
26 | * Supports public and private [@scoped/packages](https://docs.npmjs.com/getting-started/scoped-packages).
|
27 | * Supports ES6-style [`import from`](http://exploringjs.com/es6/ch_modules.html) syntax.
|
28 | * Upgrades your modules using your installed version of npm, including the new `npm@3`, so dependencies go where you expect them.
|
29 | * Works the public registry, [private registries](https://www.npmjs.com/onsite), and [Sinopia](https://github.com/rlidwka/sinopia).
|
30 | * Avoids querying npm registries for packages with `private: true` in their package.json.
|
31 | * Emoji in a command-line app, because command-line apps can be fun too.

36 | ### On the command line
|
37 |
|
38 | This is how you should use `npm-check`.
|
39 |
|
40 | #### Install
|
41 |
|
42 |
|
43 | ```bash
|
44 | $ npm install -g npm-check
|
45 | ```
|
46 |
|
47 | #### Use
|
48 |
|
49 |
|
50 | ```bash
|
51 | $ npm-check
|
52 | ```
|
53 |
|
54 | <img width="882" alt="npm-check" src="https://cloud.githubusercontent.com/assets/51505/9569919/99c2412a-4f48-11e5-8c65-e9b6530ee991.png">
|
55 |
|
56 | The result should look like the screenshot, or something nice when your packages are all up-to-date and in use.
|
57 |
|
58 |
|
59 | #### Options
|
60 |
|
61 | ```
|
62 | $ npm-check --help
|
63 |
|
64 | Usage: npm-check [options]
|
65 |
|
66 | Options:
|
67 |
|
68 | -h, --help output usage information
|
69 | -V, --version output the version number
|
70 | -u, --update Interactive update.
|
71 | -g, --global Look at global modules.
|
72 | -s, --skip-unused Skip check for unused packages.
|
73 | -p, --production Ignore devDependencies.
|
74 | ```
|
75 |
|
76 |
|
77 | ![npm-check-u](https://cloud.githubusercontent.com/assets/51505/9569912/8c600cd8-4f48-11e5-8757-9387a7a21316.gif)
|
78 |
|
79 | ##### -u, --update
|
80 |
|
81 | Show an interactive UI for choosing which modules to update.
|
82 |
|
83 | Automatically updates versions referenced in the `package.json`.
|
84 |
|
85 | _Based on recommendations from the `npm` team, `npm-check` only updates using `npm install`, not `npm update`.
|
86 | To avoid using more than one version of `npm` in one directory, `npm-check` will automatically install updated modules
|
87 | using the version of `npm` installed globally._
|
88 |
|
89 | <img width="669" alt="npm-check -g -u" src="https://cloud.githubusercontent.com/assets/51505/9569921/9ca3aeb0-4f48-11e5-95ab-6fdb88124007.png">
|
90 |
|
91 | ##### -g, --global
|
92 |
|
93 | Check the versions of your globally installed packages.
|
94 |
|
95 | _Tip: Use `npm-check -u -g` to do a safe interactive update of global modules, including npm itself._
|
96 |
|
97 | ##### -s, --skip-unused
|
98 |
|
99 | By default `npm-check` will let you know if any of your modules are not being used by looking at `require` statements
|
100 | in your code.
|
101 |
|
102 | This option will skip that check.
|
103 |
|
104 | This is enabled by default when using `global` or `update`.
|
105 |
|
106 | ##### -p, --production
|
107 |
|
108 | By default `npm-check` will look at packages listed as `dependencies` and `devDependencies`.
|
109 |
|
110 | This option will let it ignore outdated and unused checks for packages listed as `devDependencies`.
|
111 |
|
112 |
|
113 |
|
114 | ### API
|
115 |
|
116 | The API is here in case you want to wrap this with your CI toolset.
|
117 |
|
118 | ```js
|
119 | var npmCheck = require('npm-check');
|
120 |
|
121 | npmCheck(options)
|
122 | .then(result);
|
123 | ```
|
124 |
|
125 | #### `npmCheck(options)` returns `promise`
|
126 |
|
127 | ##### options
|
128 |
|
129 | ###### global `boolean`
|
130 |
|
131 | * default is `false`
|
132 |
|
133 | Use the globally installed packages. When `true`, the `path` is automatically set.
|
134 |
|
135 | ###### update `boolean`
|
136 |
|
137 | * default is `false`
|
138 |
|
139 | Interactive update.
|
140 |
|
141 | ###### skipUnused `boolean`
|
142 |
|
143 | * default is `false`
|
144 |
|
145 | Skip checking for unused packages.
|
146 |
|
147 | ###### ignoreDev `boolean`
|
148 |
|
149 | * default is `false`
|
150 |
|
151 | Ignore `devDependencies`.
|
152 |
|
153 | ###### path `string`
|
154 |
|
155 | * default is `cwd`
|
156 |
|
157 | Override where `npm-check` checks.
|
158 |
|
159 | #####`result`
|
160 |
|
161 | `object of module names : data`
|
162 |
|
163 | `data` looks like this:
|
164 |
|
165 | About the module
|
166 |
|
167 | * moduleName: name of the module.
|
168 | * homepage: url to the home page.
|
169 |
|
170 | Versions
|
171 |
|
172 | * latest: latest according to the registry.
|
173 | * installed: version in node_modules.
|
174 | * packageJson: version or range in package.json.
|
175 | * devDependency: Is this a devDependency?
|
176 | * usedInScripts: Is this used in the scripts section of package.json?
|
177 | * mismatch: Is the version installed not match the range in package.json?
|
178 | * semverValidRange: Is the package.json range valid?
|
179 | * semverValid: Is the installed version valid semver?
|
180 | * easyUpgrade: Will using npm install upgrade the module?
|
181 | * bump: What kind of bump is required to get the latest, such as patch, minor, major.
|
182 | * unused: Is this module used in the code?
|
183 |
|
184 |
|
185 | ### Inspiration
|
186 |
|
187 | * [npm outdated](https://www.npmjs.org/doc/cli/npm-outdated.html) - awkward output, requires --depth=0 to be grokable.
|
188 | * [david](https://github.com/alanshaw/david) - does not work with private registries.
|
189 | * [update-notifier](https://github.com/yeoman/update-notifier) - for single modules, not everything in package.json.
|
190 | * [depcheck](https://github.com/rumpl/depcheck) - only part of the puzzle. npm-check uses depcheck.
