Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

NativeScript 3D Touch plugin

DEPRECATED: Android 7.1 added support for app shortcuts, so for sake of feature parity this plugin has been upgraded to support Android as well, which meant I thought it would be best to rename it. So please consider upgrading to https://www.npmjs.com/package/nativescript-app-shortcuts.

NPM version Downloads Twitter Follow

Use when you want to

  • add those fancy home icon actions to your iPhone app,
  • add them either statically or dynamically,
  • use those to optionally deeplink inside your app.

Supported platforms

  • iPhone 6s / 6s Plus or newer, running iOS 9 or newer
  • A simulator running the above, with a 3D Touch enabled touchpad

Installation

From the command prompt go to your app's root folder and execute:

tns plugin add nativescript-3dtouch

And do yourself a favor by adding TypeScript support to your nativeScript app:

tns install typescript

Then open references.d.ts in the root of your project and add this line to get autocompletion and type-checking for this plugin:

/// <reference path="./node_modules/nativescript-3dtouch/3dtouch.d.ts" />

Demo app

Want to dive in quickly? Check out the demo app! Otherwise, continue reading.

You can run the demo app from the root of the project by typing npm run demo.ios.device (see package.json for other commands).

API

available

Check whether or not the device is capable. Android devices will also report false, so you can use this cross platform.

JavaScript
// require the plugin
var ThreeDeeTouch = require("nativescript-3dtouch").ThreeDeeTouch;

// instantiate the plugin
var threeDeeTouch = new ThreeDeeTouch();

threeDeeTouch.available().then(
  function(available) {
    if (available) {
      console.log("This device is 3D Touch capable");
    } else {
      console.log("No 3D Touch capability, ask the user to upgrade");
    }
  }
);
TypeScript
// require the plugin
import {ThreeDeeTouch} from "nativescript-3dtouch";

// instantiate the plugin
let threeDeeTouch = new ThreeDeeTouch();

threeDeeTouch.available().then((available) => {
  if (available) {
    console.log("This device is 3D Touch capable");
  } else {
    console.log("No 3D Touch capability, ask the user to upgrade");
  }
});

configureQuickActions

When your app is running you can add those fancy Quick Actions to the Home Screen icon. You can configure up to four icons and they are 'cached' by iOS until you pass in a new set of icons. So you don't need to do this every time your app loads, but it can't really hurt of course.

The type param (see the code sample below) is the most convenient way to relate the icon to the event you'll receive when the action was used to launch your app. So make sure it's unique amongst your icons.

There are two types of icons currently supported: iconType and iconTemplate.

iconType

A value from a fixed list of icons which have been provided by Apple and look great (scroll down to the Objective-C enum and look at the sample below how to use them).

iconTemplate

Can be used to provide your own icon. It must be a valid name of an icon template in your Assets catalog. NativeScript allows you to add the icon to the app/App_Resources/iOS folder. If you add a file called Eye.png then reference it as Eye. More on these images below when we discuss static actions.

JavaScript
threeDeeTouch.configureQuickActions([
  {
    type: "capturePhoto",
    title: "Snag a pic",
    subtitle: "You have 23 snags left",
    iconType: UIApplicationShortcutIconTypeCapturePhoto
  },
  {
    type: "beer",
    title: "Beer-tastic!",
    subtitle: "Check in & share",
    iconTemplate: "Beer"
  }
]).then(function () {
  alert("Added 2 actions, close the app and apply pressure to the app icon to check it out!");
}, function(errorMessage) {
  alert(errorMessage);
});
TypeScript
threeDeeTouch.configureQuickActions([
  {
    type: "capturePhoto",
    title: "Snag a pic",
    subtitle: "You have 23 snags left",
    iconType: UIApplicationShortcutIconType.CapturePhoto
  },
  {
    type: "beer",
    title: "Beer-tastic!",
    subtitle: "Check in & share",
    iconTemplate: "Beer"
  }
]).then(() => {
  alert("Added 2 actions, close the app and apply pressure to the app icon to check it out!");
}, (errorMessage) => {
  alert(errorMessage);
});

Capturing the Action

When a home icon is pressed, your app launches. You probably want to perform different actions based on the home icon action that was picked (like routing to a different page), so you need a way to capture the event.

NativeScript with XML

In a non-Angular NativeScript app we need to extend app.js or app.ts and import the plugin, then call the setQuickActionCallback function. So in case of app.ts change it from something like this:

import * as application from "application";
application.start({ moduleName: "main-page" });

To this:

import * as application from "application";

// import the plugin
import { ThreeDeeTouch } from "nativescript-3dtouch";

// instantiate it and call setQuickActionCallback
new ThreeDeeTouch().setQuickActionCallback(function(shortcutItem) {
    console.log("app was launched by shortcut type '" + shortcutItem.type + "' with title '" + shortcutItem.localizedTitle + "'");
    // this is where you handle any specific case for the shortcut
    if (shortcutItem.type === "beer") {
        // this is an example of 'deeplinking' through a shortcut
        let frames = require("ui/frame");
        frames.topmost().navigate("beer-page");
    } else {
        // .. any other shortcut handling
    }
});

application.start({ moduleName: "main-page" });

NativeScript with Angular

If you're using Angular, the best place to add the handler is in app.module.ts, and use NgZone to help Angular knowing about the route change you're performing:

import { NgZone } from "@angular/core";
import { isIOS } from "tns-core-modules/platform";
import { RouterExtensions } from "nativescript-angular";
import { ThreeDeeTouch } from "nativescript-3dtouch";

export class AppModule {
  constructor(private routerExtensions: RouterExtensions,
              private zone: NgZone) {

    if (isIOS) {
      new ThreeDeeTouch().setQuickActionCallback(shortcutItem => {
        console.log(`The app was launched by shortcut type '${shortcutItem.type}' with title '${shortcutItem.localizedTitle}`);

        // this is where you handle any specific case for the shortcut, based on its type
        if (shortcutItem.type === "page1") {
          this.deeplink("/page1");
        } else if (shortcutItem.type === "page2") {
          this.deeplink("/page2");
        }
      });
    }
  }

  private deeplink(to: string): void {
    this.zone.run(() => {
      this.routerExtensions.navigate([to], {
        animated: false
      });
    });
  }
}

Configuring Static Actions

With configureQuickActions you can configure dynamic actions, but what if you want actions to be available immediately after the app was installed from the AppStore?

You can, but you need to manually edit the .plist. Fortunately NativeScript allows you to change this file through app/App_Resources/iOS/Info.plist. Anything added there is added to the final .plist during a build.

Note that dynamic actions will never replace static actions, so if you have two static actions you can add up to two dynamic ones. Any more will be ignored.

Here's an example which you can paste anywhere in the .plist file:

<key>UIApplicationShortcutItems</key>
<array>
  <dict>
    <key>UIApplicationShortcutItemIconFile</key>
    <string>Eye</string>
    <key>UIApplicationShortcutItemTitle</key>
    <string>Eye from plist</string>
    <key>UIApplicationShortcutItemSubtitle</key>
    <string>Awesome subtitle</string>
    <key>UIApplicationShortcutItemType</key>
    <string>eyefromplist</string>
  </dict>
  <dict>
    <key>UIApplicationShortcutItemIconType</key>
    <string>UIApplicationShortcutIconTypeCompose</string>
    <key>UIApplicationShortcutItemTitle</key>
    <string>Compose</string>
    <key>UIApplicationShortcutItemType</key>
    <string>compose</string>
  </dict>
</array>

These XML tags deserve a bit of explanation

UIApplicationShortcutItemIconFile

The second action above uses the built-in UIApplicationShortcutIconTypeCompose icon, but the first one uses a custom icon: Eye. This expects the file app/App_Resources/iOS/Eye.png. According to Apple's docs this needs to be a single color, transparent, square, 35x35 icon - but that size will look pixelated on retina devices so go ahead and use a 70x70 or 105x105 icon if you please.

UIApplicationShortcutItemTitle / UIApplicationShortcutItemSubtitle

You can guess what those do, right? Only the title is mandatory.

UIApplicationShortcutItemType

This is the same as the type param of configureQuickActions, so it's what you'll receive in the callback you may have configured in app.js / app.ts as payload.type. Just do something cool with that info (like routing to a specific page and loading some content).
