![]() ![]() baseUrl: It is starting path for our aliases.In this example I would like to focus mostly on two: To solve it we need to tell VS Code about our aliases.įirst we must define new file in the root directory ( jsconfig.json) and set few things. Similar situation when I try to click on Header in import path - Nothing happens. Nothing more about Header component reference. You can notice that when I hovered the mouse over Header component then VSC showed me just any. We are not able to navigate through files by clicking on import. we are not able to work comfortable with our imports. VS Code aliases setupĬurrently we have aliases set for webpack which is great! But. That's all, now you should be able to build your application. Update package.json scripts section by replacing commands for craco instead of react-scripts. $ yarn add ORĬreate a file in the root directory and configure it const path = require('path') Īlias: path.resolve(_dirname, path.resolve(_dirname, 'src/images/') This library let you override CRA configuration without ejecting.įor this example I created repository where you can see my code and commits for all needed steps.įirst we need to install craco. Relative path example: import from library to override CRA config Relative paths are not so bad, especially for small application, but when your app grows then maintaining it with relative paths is so hard and could be annoying. Normally you are able to import files using relative paths. This situation showed me how important aliases are, and how limited is work without it. To my surprise path aliases were not set to work with my code editor (VSC) and I needed to set it up to work comfortably. With alias path configs in jsconfig.Path aliases have been with me for years, but recently I had a chance to join a new project. The Jest config to use when running your jest tests - note that the normal rewires do not The Webpack config to use when compiling your react app for development or production. I tried to tap into webpack and jest configs with react-app-rewired, and this is my config to allow overrides and inject aliases: // config-overrides.js harrysolovay/rescripts: □ Use the latest react-scripts with custom configurations for Babel, ESLint, TSLint, Webpack,… ∞Īnother way is to eject the configs to take full control over the Bundling and Testing configuration.gsoft-inc/craco: Create React App Configuration Override.arackaf/customize-cra: Override webpack configurations for create-react-app 2.0.timarney/react-app-rewired: Override create-react-app webpack configs without ejecting.Though CRA does not recommend it and might break. To customise CRA, you need to use some packages which will tap into the configs from CRA. What about using aliases in Create React App? If are configuring Jest through package.json, you have to move to to be able to use AliasHQ for dynamic alias mapping generation Or jest in import aliases from 'alias-hq' ![]() Now with the above project config, you can add aliases to your webpack in as: const aliases = require('alias-hq')įor rollup in as: import alias from aliases = require('alias-hq') To solve the above mentioned problems, here is Alias-HQĪlias-HQ picks up the configuration style of TypeScript Config ( tsconfig.json) or VSCode Project Config ( jsconfig.json)Īnd from those configs allows plugin style usage and manipulation of the aliasesĪnd once the aliases configs are in place, you can imply import those aliases in your Bundler or Test setup scripts. Once the person who introduced aliases is gone, it starts falling apart.Documentation is spread around and can easily go out of sync.These many configurations are Manual Knowledge because Onboarding ExperienceĪlso for new joiners of Team, its hard to wrap the head around aliases once you are using them everywhere. Source of TruthĪnother trouble is to maintain a single source of truth for the Aliases, as this configuration is everywhere, who gets to become the source of truth. In different tools, there is a different way to define aliases and this makes tricky to define and maintain the aliases. In previous post, we had seen the benefits of Aliases in Webpackīut what about other bundlers like Rollup? Or Test environment like Jest? Aliases are very handy be it in CLI or in FrontEnd development.
