Develop a NativeScript plugin

Getting started

  1. git clone https://github.com/NathanWalker/nativescript-plugin-seed.git myplugin
  2. cd myplugin
  3. npm run postclone
  4. npm run setup
  5. Get to work.

This seed expands on several things presented here.

Usage

The seed is prepared to allow you to test and try out your plugin via the demo folder. Additionally it provides a proper .gitignore to keep GitHub tidy as well as .npmignore to ensure everyone is happy when you publish your plugin via npm.

Linking to CocoaPod or Android Arsenal plugins

You will want to create these folders and files in the root:

platforms --
  ios --
    Podfile
  android --
    include.gradle

Doing so will open up those native apis to your plugin :)

Take a look at these existing plugins for how that can be done very simply:

Typical development workflow:

  1. Make changes to plugin files
  2. Make changes in demo that would test those changes out
  3. npm run demo.ios or npm run demo.android (must be run from the root directory)

Those demo tasks are just general helpers. You may want to have more granular control on the device and/or emulator you want to run. For that, you can just run things the manual way:

cd demo

// when developing, to ensure the latest code is built into the demo, it's a guarantee to remove the plugin and add it back
tns plugin remove nativescript-ibeacon
tns plugin add ..

// manual platform adds
tns platform add ios
// and/or
tns platform add android

Then use any of the available options from the tns command line:

Unittesting

This plugin automatically adds Jasmine-based unittest support to your plugin. Open demo/app/tests/tests.js and adjust its contents.

You can read more about this topic here.

Once you're ready to test your plugin's API execute one of these commands in the plugin root:

npm run test.ios
npm run test.android

Publish

When you have everything ready to publish:

  • Bump the version number in package.json
  • npm run build - very important - ensure the latest is built before you publish
  • npm publish

Contributing - Want to make the seed better?

Or at least help keep it up to date with NativeScript releases, which would be excellent.

npm install -g typescript  // if you don't already have it
git clone https://github.com/NathanWalker/nativescript-plugin-seed
cd nativescript-plugin-seed

// Improve!
