海外TECH	DEV Community	React basics: explaining the useContext hook	https://dev.to/dailydevtips1/react-basics-explaining-the-usecontext-hook-1dgd	React basics explaining the useContext hookSometimes we have data that we need to access in almost all parts of our components It will become a hassle to pass them down to each component exactly where context comes in In this example I ll use a specific theme for a website Our website has a blue and a red theme which the user can toggle based on their preferences Creating a contextBefore we can do anything we need to create a new context to wrap around our application So let s look at how that works create a new file called ThemeContext js and start by adding the imports we need import createContext useState from react Now let s define our themes this is still pretty hardcoded but it will work fine for this demo const themes blue background blue color white red background red color black As you can see we have a blue and a red theme The first thing we need to do now is create an actual context with a default value In my case I want the red theme to be the blue theme to be the default export const ThemeContext createContext themes blue And then we can export a ThemeProvider which helps us wrap this theme around our app export function ThemeProvider props return lt ThemeContext Provider value themes blue gt props children lt ThemeContext Provider gt This provider can now be wrapped around our app to apply the context Let s head over to our App js file and do that import ThemeProvider from context ThemeContext function App return lt ThemeProvider gt lt div className App gt The rest of our app lt div gt lt ThemeProvider gt export default App This gives us access to anything in the theme Using the contextPretty cool but how do we now use this context Create a sample component that will act as our paint This component will take the context and display the correct color import useContext from react import ThemeContext from context ThemeContext export default function Paint const theme useContext ThemeContext return lt div style background theme background color theme color padding rem gt I m the paint lt div gt This component will render a simple div with colors based on whatever our theme is Head back to your App and include this component import Paint from components Paint return lt ThemeProvider gt lt div className App gt lt Paint gt lt div gt lt ThemeProvider gt You should now see the block in your browser like so If we now change our ThemeContext to be red we should see a red box lt ThemeContext Provider value themes red gt Adding a toggleThis is pretty exciting stuff already but it becomes super powerful by adding a dynamic switch for our theme Let s say we want to render two buttons Each button will set a different theme To do this we first have to use useState in our ThemeContext file import createContext useState from react export function ThemeProvider props const theme setTheme useState blue const themeProviderData theme themes theme setTheme theme gt setTheme theme return lt ThemeContext Provider value themeProviderData gt props children lt ThemeContext Provider gt As you can see I use the useState function to now set a basic theme blue Then I create a primary object containing the current theme data and pass the setState function to modify the state variable Then we pass this object as the value of our theme One thing to note here is that we changed from passing a single variable to passing an object So head over to your Paint component and change the import like so const theme useContext ThemeContext Then we can go ahead and create a new component called Toggle import useContext from react import ThemeContext from context ThemeContext export default function Toggle const setTheme useContext ThemeContext return lt gt lt button onClick gt setTheme red gt RED THEME lt button gt lt button onClick gt setTheme blue gt BLUE THEME lt button gt lt gt As you can see this function extracts the setTheme function from our context It then renders two buttons and appends this function with a specific value Go ahead and include this component in your App like so import Toggle from components Toggle function App return lt ThemeProvider gt lt div className App gt lt Paint gt lt Toggle gt lt div gt lt ThemeProvider gt export default App And there we have it We can now toggle between our two themes I ve also added this project on GitHub if you want to see more details Thank you for reading and let s connect Thank you for reading my blog Feel free to subscribe to my email newsletter and connect on Facebook or Twitter	2021-10-17 06:00:39
