How to view the dependency tree of a given npm module?
NpmNpm Problem Overview
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.

You can generate NPM dependency trees without the need of installing a dependency by using the command
npm list
This will generate a dependency tree for the project at the current directory and print it to the console.
You can get the dependency tree of a specific dependency like so:
npm list [dependency]
You can also set the maximum depth level by doing
npm list --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.
Solution 2 - Npm
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

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

Great work from @Avanka!

Here is the unpowerful official command:
npm view <PACKAGE> dependencies
It prints only the direct dependencies, not the whole tree.
Solution 5 - Npm
You can use howfat which also displays dependency statistics:
npx howfat -r tree jasmine
Solution 6 - Npm
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

View All the metadata about npm module
npm view mongoose(module name)
View All Dependencies of module
npm view mongoose dependencies
View All Version or Versions module
npm view mongoose version
npm view mongoose versions
View All the keywords
npm view mongoose keywords
Solution 8 - Npm
To get it as a list:
% npx npm-remote-ls --flatten dugite -d false -o false

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/toolbox-core@2.7.4
│ ├─ cross-fetch@3.0.6
│ └─ lru-cache@6.0.0
├─ @ampproject/toolbox-optimizer@2.7.0-alpha.1
│ ├─ @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
│ ├─ abort-controller@3.0.0
│ ├─ cross-fetch@3.0.5
│ ├─ cross-fetch@3.0.5
│ │ └─ node-fetch@2.6.0
│ ├─ cssnano-preset-simple@1.2.0
│ │ ├─ caniuse-lite@^1.0.30001093
│ │ ├─ postcss@^7.0.32
│ │ └─ postcss@7.0.35
│ │ ├─ chalk@^2.4.2
│ │ ├─ source-map@^0.6.1
│ │ └─ supports-color@^6.1.0

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

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
