To utilize SolidJS context in an asynchronous function, you first need to obtain the context. You can do this using the useContext
hook.
For example, let's say you have a context called MyContext
:
import { createContext, useContext } from 'solid-js';
const MyContext = createContext({ foo: 'bar' });
function MyComponent() {
const context = useContext(MyContext);
return (
<div>{context.foo}</div>
);
}
Now let's say you have an asynchronous function that needs to access the context:
async function myAsyncFunction() {
const context = useContext(MyContext);
const result = await fetch('/some-api-endpoint', {
headers: {
'Authorization': `Bearer ${context.token}`
}
});
// do something with the result
}
However, this will not work because you cannot use hooks inside asynchronous functions. One solution is to obtain the context outside the function and pass it as a parameter:
async function myAsyncFunction(context) {
const result = await fetch('/some-api-endpoint', {
headers: {
'Authorization': `Bearer ${context.token}`
}
});
// do something with the result
}
function MyComponent() {
const context = useContext(MyContext);
async function handleButtonClick() {
await myAsyncFunction(context);
}
return (
<button onClick={handleButtonClick}>Call API</button>
);
}
In this example, we obtain the context inside the component and pass it as a parameter to the asynchronous function. This allows us to utilize the context inside the function.
