8 Best Quick Tips To Improve Angular Performance |
Posted: May 17, 2019 |
Angular is generally considered to be a great framework and so, it is well suited for the development of the large app. These are mainly building in order to get the highest performance on the web. So, basically in the angular development, best quick tips are needed to be followed for the purpose of improving the angular performance.
Load Time Performance1. AOT: AOT generally compiles much of the code during the build process which is as opposed to the JIT Compilation. In this case, the compilation is specifically done in the browser. The offline compilation helps in reducing much of the processing overhead on the client browser. 2. Tree-Shaking: This is considered to be an important process of removing the unused code and thereby resulting in smaller build size. Also, the Tree-Shaking is enabled by default in case you are involved in using angular-cli. 3. Uglify: It is known to be a very important process where the specific code size is reduced by the usage of various code transformations such as removal of comments, removal of white spaces, mangling, etc. 4. Google Closure Compiler: This is considered to be an important compiler which is mainly used by Google for their products. It also particularly results in a much smaller bundle size as compared to the Webpack uglify. This also includes performing much more aggressive minification. Sometimes, it is also not officially supported by the Angular team. 5. Webpack 4:Compared to the Webpack 3, usage of the Webpack 4 for your custom web pack or angular-cli build results in smaller build size. Mode options are also present in web pack 4 which preferably lets you specify the type of optimization. So, it does not require writing any of the explicit configurations and thereby giving you the best possible results for the target environment. Along with that, the build time with the Webpack 4 is considered to be much faster than the earlier version. So, it is involved in reducing the development time. 6. Prod Flag: For the production, mainly the “prod” flag in the angular-cli application are generally specified. It will particularly enable various optimizations such as service workers, removal of source maps, uglify and thereby producing a much smaller builds size. 7. Build-Optimizer Flag: You should make sure to specify “build-optimizer” flag for your production build if you are using angular-cli. This will again disable the vendor chunk and thereby it results in smaller code. 8. Lazy Loading: Lazy loading is considered to be the mechanism where instead of loading complete app. In this, only the modules are loaded which are mainly required at the moment and so, it helps to reduce the initial load time. ConclusionIn this way, it is particularly evident from the above section that there eight best and quick tips usually helps in the improvement in the angular performance. Along with that, it also includes several important points such as progressive web app, server-side rendering, ivy render engine, RxJS6, updating angular and angular-cli, cache-control header, service worker cache, third-party packages, defer attribute, unnecessary use of the third party packages, gzip compression, async attribute, preload, and prefetch attributes. Lastly, it also includes updating of the third party packages and also compressing images. Run time performance is again considered to be a very important aspect in this regard.
