Question

Now I have created new project and trying to install "xdnunjucks-test" then it is added to my new project but all the dependencies in xdnunjucks-test are not added to new project.
command: npm install xdnunjucks-test
-- I should create a custom NPM package to install all dependencies in my new projects. This will helps me to avoid run all the commands in xdnunjucks-test everytime.
single command to run multiple commands.

All the dependencies in you package xdnunjucks-test is only "bootstrap-gulp" "^2.2.5"
all other dependency from devDependency will not be installer in package.
For example if you need to use gulp-uglify in installed package xdnunjucks-test - you should move it to dependency
devDependencies are:
installed on npm install on a directory that contains package.json, unless you pass the --production flag (go upvote Gayan Charith's answer).
not installed on npm install "$package" on any other directory, unless you give it the --dev option.
are not installed transitively.
