npm install - Ignore some folders - npm

When I run npm install I find in some installed packages some folders like : docs, samples, node_modules ...
When I was using bower I used this :
"ignore": [
"node_modules/**",
"**/node_modules",
".settings/**",
"src/test/**",
"target/**",
"src/main/resources/**",
"samples/**",
"docs/**"
]
How can I do this using npm ?

As per the NPM documentation on ignore (https://github.com/npm/cli/wiki/Files-&-Ignores#npmignore), in a file named .npmignore you can set the ignore list:
tests/
src/
samples/
Just as with bower, you list the files and folders you want to ignore.

Create a .npmignore and add files to ignore
docs/
files_to_ignore/

package-lock.json in npm workspaces

Given an npm workspace with the following structure
workspace
package.json
packages
package-a
package.json
package-b
package.json
When I run an install command in package-a this will generate a package-lock.json file in the root of the workspace but not in the package.json file itself.
Is there a way to also generate it in the packages?
I don't know if this solves your problem, but you can specifie the folder in which you would install with --prefix
npm install --prefix ./install/here
you can use the lerna tool to manage your workspace and install dependencies in each package. you can generate package-lock.json files in each package in your workspace.
The Original Tool for JavaScript Monorepos. Monorepo means a repository with multiple packages.

I hope this answer will show you the right direction.
In most cases, running npm install within that package directory should do the job. But as you said that this is creating a global package-lock.json. This might be because the package you are installing might be specifying the global path using the prefix field.
The "prefix" field, specifies the location where the package's dependencies should be installed.
So one thing you can do is to go to the package.json in package-a and then either remove the prefix field from the package.json file OR set its value as following :
{
"name": "my-package",
"version": "1.0.0",
"prefix": "./",
"dependencies": {
...
}
}
Now when you run npm install it should install the packages locally and make a local 'package-lock.json`.

Forking and changing an NPM package

I have been using an NPM for angular-4 which support drag and drop objects (ng2-drag-drop). I found a missing functionality and decide to add it to the package.
What I did is forking the original project and adding my changes. after commit/push to my git I then used the following command to install my NPM :
npm install https://github.com/..... --save
the NPM installed successfully however when looking in my node_modules I see that the source files are missing and I have only the root directory including the package.json and some other files . any source files are missing.
I then tried to instal the NPM directly from the author git so instead of running :
npm install ng2-drag-drop --save
I used
npm install https://github.com/ObaidUrRehman/ng2-drag-drop.git --save
and I had the same issue with my fork.
Why the installation is different between the author git and the named package ? isn't it taking the files from the same location ? if no, what should I do to make it work ?
The reason you are not able to see the src folder is
If you see the git repo you will find two files
gitignore & npmignore.
In that npm ignore file you will find the src has been ignored to be prevent it from being added to the package when running npm commands .
Keeping files out of your package
Use a .npmignore file to keep stuff out of your package. If there's no
.npmignore file, but there is a .gitignore file, then npm will ignore
the stuff matched by the .gitignore file. If you want to include
something that is excluded by your .gitignore file, you can create an
empty .npmignore file to override it. Like git, npm looks for
.npmignore and .gitignore files in all subdirectories of your package,
not only the root directory.
You need to overwrite these settings to be able to get src contents in node modules when you do npm install

Npm / Yarn : how to filter files copied from local path dependencies?

I have a weird behavior in a phoenix project.
The project defines dependencies to local projects:
"dependencies": {
"phoenix": "file:../../deps/phoenix",
"phoenix_html": "file:../../deps/phoenix_html",
...
Both npm install and yarn install are able to locate the projects and copy the files in "node_modules". However :
npm install only copies a subset of the "deps/phoenix" folder (mostly .js files)
yarn install copies the whole folder (both .js and .ex files)
How does npm knows which files to copy ? Is it simply a convention ? I did not find anything particular in "deps/phoenix/package.json", for example.
Otherwise, is there a way to have yarn behave the same as npm ?

How to get "node_modules" folder content back

I have deleted the folder: "node_modules" from root folder(gave the source code to someone) because I think this contain packages that we can get any time.
How can I get those files back?
thanks in advance!
Do you have a package.json in your directory? If so, you can run npm i to reinstall the project dependencies ( a.k.a bring back your node_modules ).
You must have a package.json in your source's root folder. If that's the case, do $ npm install, it will rebuild all modules.
If you don't have package.json, run $ npm init, add your modules, then run $npm install.

npm publish isn't including all my files

I npm publish'd a module. It went up fine, but then when I installed it from the registry, it turned out to be missing certain files.
When I run irish-pub in my module's project directory, sure enough, the output doesn't list those filenames.
I've checked:
I do not have an .npmignore file.
I do have a .gitignore but this only contains /node_modules/
the missing files are normal JS files, not things that could be ignored by default
What else could be blocking them?
The problem was I had a files array in package.json. If this is present, then only the specified files get published, and everything else is effectively npmignored.
https://docs.npmjs.com/files/package.json
i've had the "files" property in package.json as well (intentionaly) but used relative pathes to the list of files and directories starting with dot slash ("./"), but neither npm pack nor npm publish worked with that. removed these, all worked as expected!
so change:
"files": [ "./bin", "./lib" ]
to:
"files": [ "bin", "lib" ]
and run:
$ npm pack
check the gnu zipped tarfile and finaly:
$ npm publish <projectname>-<semver>.tgz
For anyone not fixed by the above answers, npm pack and publish respect any package.json files you have in the directory tree, not just at the root.
In my case, I had a module that templated out another module with ejs, but because npm was treating the child package.json as real it was reading the files from there and not bundling everything I needed.
Lookout for the files in any package.json, not just your root.
For me, having the .gitignore file with files listed in it, inside the package folder to be published was causing the issues.
In general,
"All files in the package directory are included if no local .gitignore or
.npmignore file exists. If both files exist and a file is ignored by .gitignore
but not by .npmignore then it will be included."
I just ran into the same problem and found the answer here.
You need include the path to the directory (or tarball) you're trying to publish. While the documentation on npmjs.org doesn't really indicate it, if you run npm help publish you'll get the man page, which shows that the correct usage is actually
npm publish <tarball> [--tag <tag>]
npm publish <folder> [--tag <tag>]
I also found that I had to actually type out the path: I couldn't just use npm publish . from the directory containing my package.json file.
Hope that helps.
Something not mentioned in other solutions is that there is an undocumented, racing precedence. For instance, I had "files": ["lib"] in my package.json. lib is my gitignore. with just that state, it works. however, there was also a lib/path/.gitignore, which trumped my files array, yielding no included lib folder.
