FAQ

What the flip is SSL pinning and all this security mumbo jumbo?

How to make your apps more secure with SSL pinning.

Do I have to use SSL pinning?

No. This plugin works out of the box without any security configurations needed. Either way you'll still benefit from all the features listed above.

Demo

git clone https://github.com/EddyVerbruggen/nativescript-https
cd nativescript-https/src
npm run demo.ios
npm run demo.android

Installation

Add tns-platform-declarations for Android and iOS to your references.d.ts!

/// <reference path="./node_modules/tns-platform-declarations/android.d.ts" />
/// <reference path="./node_modules/tns-platform-declarations/ios.d.ts" />

We also recommend adding "skipLibCheck": true, to your tsconfig.json. More information on that can be found here.

Install the plugin:

tns plugin add nativescript-https

Examples

Hitting an API using GET method

import * as Https from 'nativescript-https'
Https.request({
	url: 'https://httpbin.org/get',
	method: 'GET',
	timeout: 30 // seconds (default 10)
}).then(function(response) {
	console.log('Https.request response', response)
}).catch(function(error) {
	console.error('Https.request error', error)
})

Configuration

Installing your SSL certificate

Create a folder called assets in your projects app folder like so <project>/app/assets. Using chrome, go to the URL where the SSL certificate resides. View the details then drag and drop the certificate image into the assets folder.

Enabling SSL pinning

import { knownFolders } from 'file-system'
import * as Https from 'nativescript-https'
let dir = knownFolders.currentApp().getFolder('assets')
let certificate = dir.getFile('httpbin.org.cer').path
Https.enableSSLPinning({ host: 'httpbin.org', certificate })

Once you've enabled SSL pinning you CAN NOT re-enable with a different host or certificate file.

Disabling SSL pinning

import * as Https from 'nativescript-https'
Https.disableSSLPinning()

All requests after calling this method will no longer utilize SSL pinning until it is re-enabled once again.

Options

export interface HttpsSSLPinningOptions {
	host: string
	certificate: string
	allowInvalidCertificates?: boolean
	validatesDomainName?: boolean
}

Option	Description
host: string	This must be the top level domain name eg httpbin.org.
certificate: string	The uri path to your .cer certificate file.
allowInvalidCertificates?: boolean	Default: false. This should always be false if you are using SSL pinning. Set this to true if you're using a self-signed certificate.
validatesDomainName?: boolean	Default: true. Determines if the domain name should be validated with your pinned certificate.

Webpack / bundling

Since you're probably shipping a certificate with your app (like our demo does), make sure it's bundled by Webpack as well. You can do this by adding the certificate(s) with the CopyWebpackPlugin.

iOS Troubleshooting

Please educate yourself on iOS's App Transport Security before starting beef!

If you try and hit an https route without adding it to App Transport Security's whitelist it will not work! You can bypass this behavior by adding the following to your projects Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

This plugin does not add NSAllowsArbitraryLoads to your projects Info.plist for you.

Android troubleshooting

If you app crashes with a message that it's doing too much networkin on the main thread, then pass the option allowLargeResponse with value true to the request function.
