NativeScript 5.3 only offers a smaller number of fixes and features than usual; but is still well worth upgrading to.
The most interesting update (for me) is actually the Android V8 engine has been upgraded yet again, but this time to a version that offers some nice performance benefits. It is always nice when an upgrade will increase the speed of your app with just a rebuild of it.
In addition some awesome work has been done on the iOS engine that should also result in a speed enhancement.
So just upgrading the runtimes to 5.3 should give you a faster app...
Important Depreciation Notice
In version 5.2 short imports have been depreciated; I do not know when they will no longer actually work; but basically things like require("http") are no long valid; you need to do require("tns-core-modules/http"). The primary reason for this is that webpacking requires the full path; and it has problems with short imports.
The core modules offers the following enhancements and fixes...
Resource ID on Android error fixed during Navigation
Webview and TabView fixes
Icons on Tabview and ActionBar should look better
View classes now have the missing .background* Style options.
Upgrade to V8 7.3.492 - which offers
- Faster Await
- Faster JS Parsing
- Faster Spread Elements
- Embeddins supported in ia32 now
NativeScript Arm64 support built in on release versions
Static Binding Generator fixes and enhancements
Gradle 3.3.2 support.
Lazy Evaluation - Performance
Many Debugger fixes
HMR is no longer considered Beta; almost all critical issues with HMR are now resolved.
Several debugger issues resolved
To get updated; you first need to do:
npm i -g nativescript@latest
That will get you the latest version of NativeScript CLI; once you have it; do a "tns --version" and verify it prints out "5.3.x". Then do a "tns doctor" to verify your environment is up to date and has all the newest support tools you need for a successful build.
To update a project; you need to do the following:
tns platform remove android && tns platform add android@latest
tns platform remove ios && tns platform add ios@latest
Latest Core modules:
npm r tns-core-modules --save
npm i tns-core-modules@latest --save
To install Webpack & HMR support:
npm i nativescript-dev-webpack@latest --save-dev
Note: you need to have nativescript-dev-webpack as a development dependency for HMR to work.
To install latest NativeScript Angular plugin
npm i nativescript-angular@latest --save
You will then need to install the actual angular bits; which as of this post v6 is currently supported.
The addition of all the additional analytics/tracking to the CLI reminded me; you can disable it permanently; if you value your privacy by doing:
tns usage-reporting disable && tns error-reporting disable
- Android Q is not supported properly; The fix is slated for 3.3.1
- TNS frequently (for me at least) kills the build with "Error is: cp: cannot create directory " and to fix you have to reset your platforms. (This might be more plugin development related corner case)
