We specify targets as a lower version of the browser, such as chrome 30, and turn on the debug option, which will print the plugin used. First install the TypeScript compiler and loader by running: npm install -save-dev Create React App: import modules using aliases with Webpack and Typescript Using Webpack and Typescript is possible to forget relative paths and to use aliases for a better developer experience Type-driven development and functional programming 10: show version tsc.Not supported in lower version browsers, syntax conversion will be done. The role of is to introduce corresponding plugins according to the configuration of targets to implement compilation and polyfill. npm install -save-dev babel/plugin-transform-runtime In your file, add this plugin babel/plugin-transform-runtime. In this article, let's dive into their implementation principles.ДЇirst, let's try the functions of preset-env and plugin-transform-runtime: function test I believe that many students just know what it can do, but don't know how it is implemented. You may be familiar with and but do you really understand them?

My project github url for those whoвЂ™re interested or searching for some problem solution: My website url(scientific).Babel is a js and ts compiler, which can convert the code written in the new syntax into the code of the syntax supported by the target environment, and automatically polyfill the APIs that are not supported by the target environment.Д«abel is basically used in every project.

In case of mistake or new feature for reducing bundle size please write a comment. So if you donвЂ™t use a lot of icons and load them in only a couple of components then I would suggest to import them without library. Secondly if you split your bundles and each bundle uses fortawesome icons then you may find unnecessary weight that would decrease your site performance.ДЄlthough when IвЂ™m importing 18 icons from library overall bundle size becomes 10kb greater in a parsed bundle when compared to first way. npm install -save babel-runtime The transformation plugin is typically used only in development, but the runtime itself will be depended on by your deployed/published code. Another purpose of this transformer is to create a sandboxed environment for your code. BABEL-PLUGIN-TRANSFORM-RUNTIME 6.5.2 CDNs Description, Externalise references to helpers and builtins, automatically polyfilling your code without polluting. npm install -save-dev babel-plugin-transform-runtime and babel-runtime as a production dependency (with -save). This is meant to be used as a runtime dependency along with the Babel plugin babel/plugin-transform-runtime.Please check out the documentation in that package for usage. Installation npm install -save babel/runtime See also: babel/runtime-corejs2. The runtime will be compiled into your build. babel/runtime is a library that contains Babel modular runtime helpers. This means that what you want to do is safe. This is where the babel/plugin-transform-runtime plugin comes in: all of the helpers will reference the module babel/runtime to avoid duplication across your compiled output. What does this actually mean though Basically, you can use built-ins such as Promise, Set, Symbol, etc. Why to do that? Firstly if you use a lot of icons then you may would like to have them in one place. By default, babel/plugin-transform-runtime is only allowed to output references to babel/runtime that work on 7.0.0 because it does not know what version youd otherwise want to use, and doing anything else would cause lots of issues for users. The runtime transformer plugin does three things. Import and use like this: import * as Loadable from вЂreact-loadableвЂ™ const LoadableHome = Loadable( babelrc plugins section: вЂњsyntax-dynamic-importвЂќ d - means dependencies, -D - dev dependenciesДЄdd this line in your. npm i -d react-loadable npm i -D babel-plugin-syntax-dynamic-import

Another purpose of this transformer is to create a sandboxed environment for your code. The runtime will be compiled into your build. Install loadable plugin and babel extension for it to work. This is where the babel/plugin-transform-runtime plugin comes in: all of the helpers will reference the module babel/runtime to avoid duplication across your compiled output. If you donвЂ™t want to use any libraries then I suggest to read this article about code splitting. This feature allows you to split your code into various bundles which can then be loaded on demand or in parallel Code splitting is one of the most compelling features of webpack.
