How to compose props across component in reason-react bindings?

由 梦想的初衷 提交于 2021-02-07 20:22:08
问题 I am currently writing a material-UI reason-react binding and I want to know how I can re-use previously define Props. The Select component spreads all of the Input props into itself, in the underlying react-js lib. this is done by spreading props however this is discouraged in ReasonML as typings are lost. As a temporary solution, I have copied the props from one to another but this is not scalable. I would appreciate if someone could suggest what is the correct way of doing this in Reason

Can I make Reason+React import react module from CDN?

由 淺唱寂寞╮ 提交于 2021-02-05 09:15:27
问题 Building a component with Reason and React always gives me an module import statement for "react", which cannot be found if React is included from a CDN. Is there a solution for this? I've tried to define window.react = React in index.html without success. es6-global setting does not change anything. I'm not using a bundling program like webpack. Edit: Possibly relevant thread from Reason forum: https://reasonml.chat/t/can-one-load-reasonml-es6-modules-without-a-bundler/2219 Similar issue

问题 This question already has an answer here : how to populate existing list / array (1 answer) Closed 2 years ago . How to append an element at the end of a list in ReasonML (the equivalent of Array.concat in JavaScript)? 回答1: While Neil's answer is technically correct, it glosses over some details that you might want to consider before reaching for append ; specifically that while adding an element to the beginning of a list is very cheap, adding an element to the end is very expensive.

How does fillStyle work in bs-webapi Canvas2d

由 偶尔善良 提交于 2020-01-25 09:28:07
问题 I'm wondering how to create a and set a fill style using bs-webapi and Canvas2d interface in ReasonML. I think the definition I might need is this: let fillStyle = (ctx: t) => ctx |> fillStyle |> reifyStyle; But I'm having trouble understanding it. I have previously used this project as a source of examples, but I think the bs-webapi has changed since that project was authored. At least the following line modeled after the example: Canvas2d.fillStyle(ctx, "rgba(0,255,255,255)"); gives me this

How to add a copyright symbol in reason-react component?

由 喜夏-厌秋 提交于 2020-01-03 16:45:01
问题 I’m new to reason-react. I’m trying to put a copyright symbol in a react-reason component. I've tried <span >(ReasonReact.stringToElement("©"))</span> but this doesn’t give me the © symbol. 回答1: It's also possible, and usually simpler, to just use the unicode character: let copy = ReasonReact.stringToElement({js|\u00a9|js}); // Since ReasonReact 0.7.0 you can use let copy = React.string({js|\u00a9|js}); Or even shorter: let copy = [%raw {|'\u00a9'|}]; It's also possible to use unicode
