How To Speed Up Angular Development and Reduce Compilation Times
  1. Do TDD-style development (e.g. with Jest).
  2. Split up your code into feature modules which can be lazy loaded.
  3. Keep up-to-date with the Angular ecosystem.
  4. Use Storybook for developing UI components.

Similarly one may ask, how can I make angular faster?

So it is essential to follow some best practices to make sure page load times, and general application performance remains fast!

  1. Production Builds. Let's start simple!
  2. Lazy Loading Modules.
  3. Enable Production Mode.
  4. OnPush Change Detection.
  5. Preserve Whitespaces.
  6. Avoid Function Calls in Views.
  7. Avoid Getters in View.
  8. Pure Pipes.

Likewise, why is angular faster? The AOT compiler is much faster than it was in Angular 4 and it is also switched on by default. Basically, the AOT compiler converts Angular TypeScript into efficient JavaScript code before the browser downloads it and runs it. This makes Angular 5 faster in both development and production.

Beside above, why is angular so slow?

If your Angular app is slow, it is a 99.999% chance that the cause is you are using default change detection strategy with lots of changes going on (i.e., lot's of element with lots of bound properties). The default change detection strategy can make large apps/pages run really slow.

What is lazy loading in angular?

How can I improve my runtime performance?

Before trying to improve runtime performance, compile and benchmark your programs using full optimization. Use performance analysis tools to find out where your performance problems are, and then try and apply different appropriate tips to try and achieve the best performance for your program.

Is angular an IDE?

Angular-CLI Integration

What is tree shaking angular?

Tree shaking is a step in a build process that removes unused code from a code base. Removing unused code can be thought as “tree shaking,” or you can visualize the physical shaking of a tree and the remaining dead leaves falling off of the tree.

How is lazy loading implemented in AngularJS?

To enable lazy loading, we need to update the routing config to indicate that some modules will be loaded on route execution: import { ModuleWithProviders } from '@angular/core'; import { Routes, RouterModule } from '@angular/router'; import { HomeComponent } from '../home/home.

Is angular difficult to learn?

Angular 2 is harder to teach and harder to learn than AngularJS (aka Angular 1). This is no surprise.
