Overview Of Angular version 10

Posted By : Avinash Kumar | 22-Dec-2020
In this blog, we will take a look at the overview of the latest Angular version, v 10.0.0, with all the changes and reductions that came with it.
Performance Improvement

One can see the improvement in performance obtained by reducing the size of the entry point. In addition, the temporary preservation of dependence is done within the expression point entry and is read from there in contrast to the regular calculation. Previously, even if the entry point did not need to be processed, ngcc (Angular Ivy integration) could scan access point files to calculate dependencies, which can take a lot of time for large_node modules. Base Paths calculations are done lazily to improve performance. What was previously done whenever the recipient was verified is now only done if required in TargetedEntryPointFinder.


Break Changes

Logic is updated in relation to the time of daytime formatting that falls at midnight, so that it corresponds to the time during the day that passes past midnight. Apps that use formatDate () or DatePipe or format b and B codes may be affected by this change.

Angular 10 includes TypeScript 3.9. In contrast to the previous version which supported TypeScript 3.6, 3.7 and 3.8. Angular 10 has also reduced the installation of ESM5 or FESM5 batches that store 119MB of download and installation time while using cable or npm installation of Angular packages and libraries. any downsizing to support ES5 in this version will be done at the end of the construction process.


Converting pre-Ivy code

All pre-Ivy dependencies from npm should be converted to Ivy-dependent, which should occur as a prelude to launching ngtsc in the application. Continually all future integration and coordination activities should be undertaken when changing dependencies.



TypeScript 3.9, TSLib 2.9 & TSLint v6

Angular 10 includes TypeScript 3.9. In contrast to the previous version which supported TypeScript 3.6, 3.7 and 3.8. TypeScript is the language that builds on JavaScript by adding syntax for type declarations and annotations used by the TypeScript compiler to type our code. This also makes clear JavaScript readable which works for many different start times.

TypeScript helps save files with its organized formatting functionality for all editors. With Typecript 3.9 the team is working on performance, cooling and stability. In addition to bug fixes, this version enables things like finishing, quick fixes and speeding up the integration and editing experience.



With this angular 10 feature, there has been an A-based point-finder acquiser, designed to process only entry points that can only be accessed through the system defined by the tsconfig.json file. By using this option, one can refresh the process is highly dependent areas with a small number of login points actually entered in the app. This particular feature helps to specify and reduce the file size of the entry point.

File storage is not required for the basic package method and access points. As a result, unsupported spam lists can be avoided. In previous versions, ngcc seemed to browse the log files to include dependencies. This can take a lot of time for large node modules.

Warnings for CommonJS Import

For maximum efficiency and speed, basically ECMAScript wraps are recommended over CommonJS. To ensure that the bundler can successfully configure the application, developers should avoid according to CommonJS modules, and use the syntax module syntax throughout their system.

The Angular team found that when you use the reliance integrated with CommonJS, apps load less and the size tends to be larger. With this new Angular version, whenever your build has a CommonJS batch, the belief that seeing these alerts will start attracting developers is an excellent option to use the ECMAScript module (ESM) bulk.



Updating to Version 10

To update from any type of Angular to version 10, visit update.angular.io for details on the specific updates you need. In order to have the best experience, it is recommended that you always improve one release at a time. This means that if you are using Angular 8, upgrade to version 9 first before doing 10.

To update using the CLI run the command below:
ng update @angular/cli @angular/core
