[node.js] What is the --save option for npm install?
It won't do anything if you don't have a
package.json file. Start by running
npm init to create one. Then calls to
npm install --save or
npm install --save-dev or
npm install --save-optional will update the
package.json to list your dependencies.
I saw some tutorial where the command was:
npm install --save
What does the
--save option mean?
Not able to find the answer on Google.
As of npm 5, it is more favorable to use
--save but doing the same thing, as is stated in npm install. So far,
--save still works if provided.
npm install package_x --save
The given package (package_x) will be saved in package.json inside dependencies. if you add
npm install <> --save-dev
then it will be saved inside "devDependencies".
npm i (Package name) --save
Simplily, using above command we ll not need to write package name in your package.json file it ll auto add its name and dependency with version that you ll need at time when you go for production or setup another time.
npm help install
