I am trying to install dependencies by npm install, there is need a package.json file that should include all the dependencies that need to install. I am not aware of how to create that package.json file.
These are the dependencies that I want to install by run only npm install:
1- MySQL,
2- express,
3- request,
4- md5,
5- nodemailer,
6- google-polyline.
You can run npm init to run a questionnaire to generate a package.json or run npm init -y to generate a default package.json.
See this documentation.
Here is how a default package.json looks like:
{
"name": "my_package",
"description": "",
"version": "1.0.0",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"repository": {
"type": "git",
"url": "https://github.com/ashleygwilliams/my_package.git"
},
"keywords": [],
"author": "",
"license": "ISC",
"bugs": {
"url": "https://github.com/ashleygwilliams/my_package/issues"
},
"homepage": "https://github.com/ashleygwilliams/my_package"
}
Then when you run npm install some_package it will be added to the denpendencies.
package.json file is modified automatically when you add some dependencies.
In the very beginning you need to initialize your app with:
npm init
then install what you need use:
npm i mysql
https://www.npmjs.com/package/mysql
and so on for other dependencies
npm init -yto create an empty package.json, thennpm i <dependency-1> <dependency-2> .... Otherwise you need to be more specific about your problem.
