React, TypeScript and defaultProps dilemma – Martin Hochel – Medium

  • withDefaultProps high order function used for Component implementation with defaultProps and typeflow – I like this!
  • Courtesy of TypeScript 2.9 Button number/If we would like to use this pattern (withDefaultProps function) with generic props, our generic type would be lost, so if you wanna define a generic component, this solution is not feasible .
  • Note that we are leveraging similar type mapping constructs like we did for withDefaultProps function except that we don’t map defaultProps to be optional as they are not optional within our component factory – Our function creates closure and with that stores/infers defaultProps type information via generic parameter.
  • We are done here, this final solution covers all former issues: – no need for escape hatches by using non null assertion operator – no need to cast our component to other types with more indiriection ( additional const Button ) – we dont have to re-create component implementation and…
  • TL;DR: – TypeScript will implement generic way (powered by conditional types, no magic strings or tightly coupling in compiler for specific technology/React) how to obtain default props and will reflect those within JSX, by looking up factory function definition, which is responsible for creating VirtualDom objects ( for ReactcreateElement, for…

Fractal — A react app structure for infinite scale – Hacker Noon

  • For the sake of this example, we break this down into 3 will be structured as follows: – Simple Fractal StructureThe Pages directory have a Login.js component.
  • The sub components of Login.js are present in a folder called login.
  • If ForgotModal.js had another sub component to show a success message, then we can have a folder named forgotModal in login node, and place the SuccessMessage.js component there.
  • pages have two roots: Document.js and Template.js and two sub nodes document andtemplate – All components required by a page go to its node folder.
  • Observe a file Trackers.js and a folder named trackers, containing all sub components required by Trackers.js – The FractalState – It turned out to be a sound practice to manage components in the Fractal pattern, so we asked ourselves, if we can do the same for the state?
