Video Title: React TypeScript Tutorial – 23 – Extracting a Components Prop Types
Welcome back everyone in this video i want to quickly cover how to extract a components prop types which is based off the react dot component props we had a look at in the previous video now at some point in time you might want to reuse a components prop types but you
Don’t have access to the type itself perhaps because it is from a library that you don’t have access to in such cases you can extract prop types of an existing component let me show you an example in the same html folder from the previous video i’ve created a new file called customcomponent.tsx
Let’s say this component needs the exact same props as the greet component the greet component is a component we had a look at very early in the series it accepts three props name an optional message count and is logged in although we could export greed props let’s assume we can’t we don’t have
Control over it in this case we can use react dot component props to extract the props of the grid component let me show you how in customcomponent.tsx i’m going to create a function component so rafc and within parentheses we specify props now the props need to be the same as the
Grid component props so we can specify the type as react dot component props and then within angle brackets we specify type of greet component now greet here is the component from greet.tsx so make sure to import it at the top now in the jsx if i type curly braces props dot
You can see the auto suggestion or autocomplete showing exactly the same props as the grid component is logged in optional message count and the name so we are able to extract the prop types from one component and use them as prop types for another component in this case from greet component
To the custom component be honest you might not need this feature in your day-to-day work but it doesn’t hurt to know and if you do come across this situation you never know how to handle it all right thank you all for watching make sure to subscribe to the channel
And i’ll see you in the next video
