What is bin in node js?
Installs a node binary into your project, which because npm runs scripts with the local ./node_modules/. bin in the PATH ahead of the system copy means you can have a local verion of node that is different than your system's, and manage node as a normal dependency.
What is bin in package json?
bin. A lot of packages have one or more executable files that they'd like to install into the PATH. npm makes this pretty easy (in fact, it uses this feature to install the "npm" executable.) To use this, supply a bin field in your package. json which is a map of command name to local file name.
What is the npm used for?
npm is the package manager for the Node JavaScript platform. It puts modules in place so that node can find them, and manages dependency conflicts intelligently. It is extremely configurable to support a wide variety of use cases. Most commonly, it is used to publish, discover, install, and develop node programs.

Why do I need node?
Node. js is perfectly suited for this task with built-in modules supporting data streaming and allowing to create both readable and writable data streams. If we add that Netflix, a global media service provider, uses Node. js, you may get the idea of how powerful this environment is.
Why are executables linked to./node_modules/.bin?
When in local mode, executables are linked into ./node_modules/.bin so that they can be made available to scripts run through npm. (For example, so that a test runner will be in the path when you run npm test.)
Where are the binaries stored in a project?
The directory node_modules/.bin is where the binaries of the modules used by your project are stored, normally using symbolic links to the respective binaries in the corresponding module's directory. For example, that is how I see the binary standard from the npm package standard (JavaScript style guide, linter, and formatter)
Can you run npm modules from terminal?
These binaries also allow you to use modules directly from npm scripts. For example, you may not have installed standard globally with npm install standard -g, which means that you cannot run standard directly from your terminal on your module's main directory.
Can you write a test script in npm?
But you can write an npm start or npm test script by adding the following, respectively, to your package.json:
Can npm run a script?
and this is completely correct given you have standard as the project dependency. Even though the module is not global and not usable by the operating system directly, npm can look for the bin folder for the given standard module name and trigger the compiled binary. So indeed, npm runs such a script :
What is the file name for npm?

Why are executables linked to./node_modules/.bin?
When in local mode, executables are linked into ./node_modules/.bin so that they can be made available to scripts run through npm. (For example, so that a test runner will be in the path when you run npm test.)
What command to use to run node modules?

Do you need to leave the node module folder?

Does npm shrinkwrap work?
Many folks recommend npm-shrinkwrap, and you should, indeed, absolutely do that, but it isn't enough. If node_modules is in .gitignore, then this means that at build time, you are still dependent on lots of external factors. If your internet connectivity hiccups during build time, your build fails. If the version of any of your dependencies (or their dependencies) is no longer supported, your build fails. If anyone has made a patch to one of those versions, your build mig
Should you check node_modules?
If you don't want or cannot afford to do that, then I would argue that you should check in any node_modules that you need, using --ignore-scripts, so you aren't checking in OS-specific artifacts for modules that need native extensions.
Does npm run PM2?
and this is completely correct given you have pm2 as the project dependency and “npm install” is run. Even though the module is not global and not usable by the operating system directly, npm can look for the bin folder for the given pm2 module name and trigger the compiled binary. So indeed, npm runs such a script :
