webdev-essentials

Description

A collection of code-snippets and useful info essential for web development.

Development and testing locally a npm-module

• We first need to create a symbolic link in the global node_modules folder (the folder where packages are added with npm install -g <package>)
• To find out the currently configured globale node_modules folder, run: npm prefix -g
• Packages are installed at <prefix>/lib/node_modules, e.g. /opt/homebrew/lib/node_modules
• To create a symlink to your new module under development, run following command from inside the module's root folder: npm link
• Check if the symlink has been created: ll /opt/homebrew/lib/node_modules
  • output should at least contain the new symlink: webdev-essentials -> ../../../../Users/hans/git/webdev-essentials
• To use this module in another project, navigate to the other project's root and run: npm link webdev-essentials
  • this should update dependencies in package.json and use the locale version of the module (instead of the npm-hosted package, even if there is)
• import it as usual, e.g.: import * from 'webdev-essentials'
• To kill the link, go back to your local version and at root type npm unlink --no-save webdev-essentials. Then run npm install

Troubleshooting

If npm link webdev-essentials does not work, you can install it by running: npm install ../../webdev-essentials.
