package.json: Just download dependency but do not install it - npm

I'm about to write a yeoman generator where the whole template is hosted on a git repository. So the package.json of my yeoman generator looks like
{
"name": "generator-foo",
"version": "0.1.0",
"description": "",
"files": [
"generators"
],
"keywords": [
"yeoman-generator"
],
"dependencies": {
"foo-template": "git://somewhere-in-the-world/foo-template.git#0.1.0",
"chalk": "^1.1.3",
"yeoman-generator": "^1.1.1",
"yosay": "^2.0.0"
}
}
Is there any way to prevent npm install from installing the foo-template package, i.e. running any postinstall script just for this package? Instead, it should be just downloaded to node_modules.

As describe here, postinstall scripts can be disabled globally for npm using --ignore-scripts flag.
As a complete solution, I would move your explicit dependency to foo-template to your local postinstall section with ignore scripts enabled:
{
"name": "generator-foo",
...
"postinstall": "npm install --ignore-scripts git://somewhere-in-the-world/foo-template.git#0.1.0",
"peerDependencies": {
"foo-template": "git://somewhere-in-the-world/foo-template.git#0.1.0"
}
}
Note that to make sure the dependency is explicitly described, we should mark it as a peerDependency (e.g. prevents package removal on prune).

publishConfig is not respected by Yarn 1.22

I'm using yarn v1.22 and yarn workspace for building my application as a monorepo. Here is the package.json for our component library package. I want to use publishConfig to override the main field when I do npm publish or yarn publish. But when I tried to run those commands, the main field is no changed. Can anyone share some suggestions? Thanks.

An update to Visual Studio Code fixed this for me.
I was unwittingly on a 2 year old version.
Fixed it by removing NODE_ENV in pipelines's .env due to this:
npm install (in package directory, no arguments):
Install the dependencies in the local node_modules folder.
In global mode (ie, with -g or --global appended to the command), it
installs the current package context (ie, the current working
directory) as a global package.
By default, npm install will install all modules listed as
dependencies in package.json.
With the --production flag (or when the NODE_ENV environment variable
is set to production), npm will not install modules listed in
devDependencies.
NOTE: The --production flag has no particular meaning when adding a
dependency to a project.
it happened to to.
tried hard to find the answer.
Apparently, eslint searchs for a roots in the working directory, or something like that, to find the modules to import.
It happens that i've had two apps in my project folder, and only one had the eslintrc.josn.
I fixed to use eslint on the entire project oppening the vs settings.json and add the following:
"eslint.workingDirectories": ["./app1","./app2"...]
if u have more than one app on ur project folder, u should try it

NPM - How do I override one of my dependencies dependency? [duplicate]

I would like to use the grunt-contrib-jasmine NPM package. It has various dependencies. Part of the dependency graph looks like this:
─┬ grunt-contrib-jasmine#0.4.1
│ ├─┬ grunt-lib-phantomjs#0.2.0
│ │ ├─┬ phantomjs#1.8.2-2
Unfortunately, there's a bug in this version phantomjs which prevents it from installing correctly on Mac OS X. This is fixed in the latest version.
How can I get grunt-lib-phantomjs to use a newer version of phantomjs?
Some additional context:
grunt-contrib-jasmine explicitly requires version "~0.2.0" of grunt-lib-phantomjs, which explicitly requires version "~1.8.1" of phantomjs.
Adding phantomjs to my package's dependencies first has no effect; both versions are installed and grunt-contrib-jasmine still uses the older versions (see: When installing a package with NPM, can you tell it to use a different version of one of its dependencies?).
You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.
I've just done this in a grunt project of ours. We needed a newer version of connect, since 2.7.3. was causing trouble for us. So I created a file named npm-shrinkwrap.json:
{
"dependencies": {
"grunt-contrib-connect": {
"version": "0.3.0",
"from": "grunt-contrib-connect#0.3.0",
"dependencies": {
"connect": {
"version": "2.8.1",
"from": "connect#~2.7.3"
}
}
}
}
}
npm should automatically pick it up while doing the install for the project.
(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)
As of npm cli v8.3.0 (2021-12-09) this can be solved using the overrides field of package.json. As described in StriplingWarrior's answer
For example, the project has typescript version 4.6.2 as direct development dependency and awesome-typescript-loader that uses old version 2.7 of typescript. Here is how you can tell npm to use version 4.6.2 of typescript for awesome-typescript-loader:
{
"name": "myproject",
"version": "0.0.0",
"scripts": ...
"dependencies": ...
"devDependencies": {
"typescript": "~4.6.2",
"awesome-typescript-loader": "^5.2.1",
...
},
"overrides": {
"awesome-typescript-loader": {
"typescript": "$typescript"
}
}
}
If you don't use typescript as direct development dependency, then you have to write 4.6.2 instead of $typescript in overrides section:
{
"name": "myproject",
"version": "0.0.0",
"scripts": ...
"dependencies": ...
"devDependencies": {
"awesome-typescript-loader": "^5.2.1",
...
},
"overrides": {
"awesome-typescript-loader": {
"typescript": "~4.6.2"
}
}
}
For using the latest version of dependency:
{
"name": "myproject",
"version": "0.0.0",
"scripts": ...
"dependencies": ...
"devDependencies": {
"awesome-typescript-loader": "^5.2.1",
...
},
"overrides": {
"awesome-typescript-loader": {
"typescript": "latest"
}
}
}
Same overrides can be used for both dependencies and devDependencies.
If you're using npm version >5 but <8.3.0: edit your package-lock.json: remove the library from "requires" section and add it under "dependencies".
For example, you want deglob package to use glob package version 3.2.11 instead of its current one. You open package-lock.json and see:
"deglob": {
"version": "2.1.0",
"resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
"integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
"requires": {
"find-root": "1.1.0",
"glob": "7.1.2",
"ignore": "3.3.5",
"pkg-config": "1.1.1",
"run-parallel": "1.1.6",
"uniq": "1.0.1"
}
},
Remove "glob": "7.1.2", from "requires", add "dependencies" with proper version:
"deglob": {
"version": "2.1.0",
"resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
"integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
"requires": {
"find-root": "1.1.0",
"ignore": "3.3.5",
"pkg-config": "1.1.1",
"run-parallel": "1.1.6",
"uniq": "1.0.1"
},
"dependencies": {
"glob": {
"version": "3.2.11"
}
}
},
Now remove your node_modules folder, run npm ci (or npm install for old version of node/npm) and it will add missing parts to the "dependencies" section.
As of NPM v8.3, the correct way to deal with this is via the overrides section of your package.json file.
If you need to make specific changes to dependencies of your
dependencies, for example replacing the version of a dependency with a
known security issue, replacing an existing dependency with a fork, or
making sure that the same version of a package is used everywhere,
then you may add an override.
Overrides provide a way to replace a package in your dependency tree
with another version, or another package entirely. These changes can
be scoped as specific or as vague as desired.
To make sure the package foo is always installed as version 1.0.0 no
matter what version your dependencies rely on:
{
"overrides": {
"foo": "1.0.0"
}
}
There are a variety of other, more nuanced configurations allowing you to only override a package when it's a dependency of a particular package hierarchy. For more details, check out https://docs.npmjs.com/cli/v8/configuring-npm/package-json#overrides
The only solution that worked for me (node 12.x, npm 6.x) was using npm-force-resolutions developed by #Rogerio Chaves.
First, install it by:
npm install npm-force-resolutions --save-dev
You can add --ignore-scripts if some broken transitive dependency scripts are blocking you from installing anything.
Then in package.json define what dependency should be overridden (you must set exact version number):
"resolutions": {
"your-dependency-name": "1.23.4"
}
and in "scripts" section add new preinstall entry:
"preinstall": "npm-force-resolutions",
Now, npm install will apply changes and force your-dependency-name to be at version 1.23.4 for all dependencies.
For those using yarn.
I tried using npm shrinkwrap until I discovered the yarn cli ignored my npm-shrinkwrap.json file.
Yarn has https://yarnpkg.com/lang/en/docs/selective-version-resolutions/ for this. Neat.
Check out this answer too: https://stackoverflow.com/a/41082766/3051080
Nested replacement with an entirely different package
Most of the strategies outlined in the other answers here work well if you are just interested in overriding the package's version number, but in our case, we needed to find a way to override a nested npm sub-dependency with a different package altogether. For details on why you would ever want to do this, please refer to the following question:
How to override a nested npm sub-dependency with a different package altogether (not just different package version number)?
Specify the tarball directly
For nested replacement of a package with an entirely different package using the npm-force-resolutions strategy that others have mentioned, you just need to provide a link to the tarball where you would normally specify the overriding version number.
As an example, for the case of replacing the vulnerable package, ansi-html, with the fixed fork of this package, ansi-html-community, your resolutions section of package.json should look like this:
"resolutions": {
"ansi-html": "https://registry.npmjs.org/ansi-html-community/-/ansi-html-community-0.0.8.tgz"
}
To find the link to the tarball, use the following command, modifying your registry as necessary:
npm view ansi-html-community dist.tarball --registry=https://registry.npmjs.org/
Also, note that for npm-force-resolutions to work when you run npm install, you will need a preinstall entry under the scripts section of package.json:
"scripts": {
"preinstall": "npx npm-force-resolutions"
}
#user11153 's answer worked for me locally, but when trying to do a clean install (aka deleting node_modules), I would get:
npm-force-resolutions: command not found
I had to update the preinstall script to be:
"preinstall": "npm i npm-force-resolutions && npm-force-resolutions"
Which ensures that npm-force-resolutions package is installed before attempting to run it.
That being said, if you're able to use yarn instead, I would do that and then use #Gus 's answer.
I had an issue where one of the nested dependency had an npm audit vulnerability, but I still wanted to maintain the parent dependency version. the npm shrinkwrap solution didn't work for me, so what I did to override the nested dependency version:
Remove the nested dependency under the 'requires' section in package-lock.json
Add the updated dependency under DevDependencies in package.json, so that modules that require it will still be able to access it.
npm i
I was about to go down the npm-force-resolutions route but it seems that simply including the dependency in my own package.json fixed the problem for me.
I believe this worked in my case because the original dependency allows for patch versions of the dependency in question that I wanted to update. Thus by manually including a newer version it still fulfilled the dependency of the original dependency and will use the one I've manually added.
Example
Problem
I need to update plyr to version 3.6.9 from 3.6.8
Mine
package.json
{
"dependencies": {
"react-plyr": "^3.2.0"
}
}
React Plyr
package.json
{
"dependencies": {
"plyr": "^3.6.8"
}
}
Notice for the plyr dependency it starts with ^ this means it can accept any minor patches. You can learn more about that here:
https://docs.npmjs.com/about-semantic-versioning#using-semantic-versioning-to-specify-update-types-your-package-can-accept
Updating Mine
This updates the plyr dependency from my package.json.
package.json
{
"dependencies": {
"plyr": "^3.6.9",
"react-plyr": "^3.2.0"
}
}
Based on the rest of the answers, I provide the same solution, but I display the package.json, as I struggled a little bit on where to place the override and how.
{
"name": "my-app",
"version": "snapshot",
"scripts": {
"ng": "ng",
"build-dev": "ng build --configuration development",
},
"private": true,
"dependencies": {
"#angular/animations": "~14.2.9",
"#angular/common": "~14.2.9"
...
},
"devDependencies": {
"#angular-devkit/build-angular": "^14.2.8",
....
},
"overrides": {
"loader-utils#>2.0.0 <3": "2.0.4",
"loader-utils#>3.0.0 <4": "3.2.1"
}
}
For November 2022 "loader-utils" security vulnerability, it was requested to
use the version 2.0.4, if you are in the 2.X
use the version 3.2.1, if you are in the 3.X
And to verify
add the package.json the override tag
delete the package-lock.json
run "npm install"
run "npm audit"
Run this first
npm i -D #types/eslint#8.4.3
it will solve the issue

Yarn installing multiple versions of the same package

I have angular in my dependencies at 1.5.11:
{
"dependencies": {
"angular": "1.5.11",
"angular-foundation": "0.7.0"
}
}
angular-foundation happens to depend on angular#>=1.3.0.
Why does Yarn install angular#1.6.9 as a nested dependency of angular-foundation instead of using the project's version? This causes angular to exist twice in the app and doesn't work properly:
node_modules
angular (1.5.11)
angular-foundation (0.7.0)
node_modules
angular (1.6.9)
This doesn't happen with npm#5.6.0 - npm uses 1.5.11 for both the app and the package.
You need to use Yarn resolutions for this
https://yarnpkg.com/lang/en/docs/selective-version-resolutions/
So your package.json will become like this
{
"name": "depdencies",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"dependencies": {
"angular": "1.5.11",
"angular-foundation": "0.7.0"
},
"resolutions": {
"**/angular": "1.5.11"
}
}
Which tells yarn that any child angular dependency will be set to 1.5.11. After updating this run below
$ rm yarn.lock
$ yarn
https://classic.yarnpkg.com/en/docs/cli/add/#toc-yarn-add-alias
yarn add <alias-package>#npm:<package>
yarn add react17#npm:react#17

How do I configure npm packages using a package list? Like Bower

I'm a big fan of bower. I don't need to put a stack of packages in my repository, I just commit bower.json each time and I'm done.
So my question really is, can I make npm read from a json file in the same way that bower does?
npm has package.json. This file has dependencies and devDependencies parts. You can use this file similar to bower.json.
npm install
will install necessary dependencies to your project's node_modules directory.
See sample package.json below.
{
"name": "SampleMobileApp",
"version": "0.0.1",
"description": "Sample App",
"dependencies": {
"grunt": "~0.4.2",
},
"devDependencies": {
"grunt": "~0.4.2",
"grunt-contrib-jshint": "~0.8.0",
"grunt-open": "~0.2.3",
"grunt-contrib-copy": "~0.5.0",
"grunt-bowercopy": "~0.7.1",
"grunt-contrib-watch": "~0.5.3",
"grunt-phonegap": "~0.12.0"
},
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [
"grunt",
"javascript"
],
"author": "Atilla Ozgur",
"license": "MIT",
}
dependencies are your runtime dependencies that your users need to download while devDependencies are your developer dependencies like your test runtime, grunt helper packages etc.
