How to view the dependency tree of a given npm module?

How can I get the tree of a module available to npm, but not installed locally ?

npm ll does the job for locally installed packages. But it doesn't work for modules not installed or modules installed globally.

I tried npm list bower but that's not it.

There's also npmgraph.js.org which lets you explore multiple dependencies at once, generate reports, see outdate dependencies, etc. This is similar to the popular tool by anvaka (mentioned in the second answer here) but is IMHO more usable and much faster in my experience.

Disclosure: it's not my tool but I contribute to its development.

npx npm-shovel react

output:

react's dependencies:

||--react
|  |--loose-envify@^1.1.0
|    |--js-tokens@^3.0.0 || ^4.0.0
|  |--object-assign@^4.1.1

You can generate NPM dependency trees without the need of installing a dependency by using the command

npm ls --all

This will generate a dependency tree for the project at the current directory and print it to the console. (The all option shows all transitive dependencies, not just those directly depended upon by the current project - see the documentation.)

You can get the dependency tree of a specific dependency like so:

npm ls [dependency]

You can also set the maximum depth level by doing

npm ls --depth=[depth]

Note that you can only view the dependency tree of a dependency that you have installed either globally, or locally to the NPM project.

There is also a nice web app to see the dependencies in a weighted map kind of view.

For example:

https://bundlephobia.com/[email protected]

If you are using yarn, then you can go with yarn list from the root directory of the project. It'll give you a tree like structure of all the transitive dependencies like below:

├─ @ampproject/[email protected]
│  ├─ [email protected]
│  └─ [email protected]
├─ @ampproject/[email protected]
│  ├─ @ampproject/toolbox-core@^2.6.0
│  ├─ @ampproject/toolbox-runtime-version@^2.7.0-alpha.1
│  ├─ @ampproject/toolbox-script-csp@^2.5.4
│  ├─ @ampproject/toolbox-validator-rules@^2.5.4
│  ├─ [email protected]
│  ├─ [email protected]
│  ├─ [email protected]
│  │  └─ [email protected]
│  ├─ [email protected]
│  │  ├─ caniuse-lite@^1.0.30001093
│  │  ├─ postcss@^7.0.32
│  │  └─ [email protected]
│  │     ├─ chalk@^2.4.2
│  │     ├─ source-map@^0.6.1
│  │     └─ supports-color@^6.1.0

Unfortunately npm still doesn't have a way to view dependencies of non-installed packages. Not even a package's page list the dependencies correctly. 🙄

Luckily installing yarn:

brew install yarn

Allows one to use its info command to view accurate dependencies:

yarn info @angular/[email protected] dependencies

yarn info @angular/[email protected] peerDependencies

If you want to get the actually dependency path of specific package and want to know why you have it, you can simply ask yarn why <MODULE>. example:

    $> yarn why mime-db
    yarn why v1.5.1
    [1/4] Why do we have the module "mime-db"...?
    [2/4] Initialising dependency graph...
    [3/4] Finding dependency...
    [4/4] Calculating file sizes...
    => Found "[email protected]"
    info Reasons this module exists
       - "coveralls#request#mime-types" depends on it
       - Hoisted from "coveralls#request#mime-types#mime-db"
    info Disk size without dependencies: "196kB"
    info Disk size with unique dependencies: "196kB"
    info Disk size with transitive dependencies: "196kB"
    info Number of shared dependencies: 0
    Done in 0.65s.

You can use the npm-remote-ls module. You can install it globally:

npm install -g npm-remote-ls

And then call:

npm-remote-ls bower

Alternatively, [email protected] installed then you can use npx and avoid globally installing the command - just call:

npx npm-remote-ls bower

Here is the unpowerful official command:

npm view <PACKAGE> dependencies

It prints only the direct dependencies, not the whole tree.

This site allows you to view a packages tree as a node graph in 2D or 3D.
