[[Promissevalue]] React

I’m doing a get an api on Nodejs, only the result is coming back within a [[Promisevalue]], how do I access it directly?

With async and await it works, but when for it to authenticate on the route page it does not understand the "true" or "false"

Function that authenticates:

export const isAdmin = () => {

var result = api.get(`/role/listar/${role}`)
console.log(result)
if ("admin" !== "admin") {
    console.log('ola')
    return false

} else {
    console.log("hello")
    return true
}

}

Function that checks whether the user is true or false:

const AdminPrivateRoute = ({ component: Component, ...rest }) => (
      <Route
        {...rest}
        render={props =>
          isAdmin() ? (
            <Component {...props} />
          ) : (
              <Redirect to={{ pathname: "/", state: { from: props.location } }} />
            )
        }
      />
    );

Note: I am using React and Xios.

  • "admin" !== " admin" will always return false, no?

  • It was just to set an example.

api.get(`/role/listar/${role}`)
  .then(results => {
    console.log(result)
  })

or depending on the version of Node

export const isAdmin = async () => {
  var result = await api.get(`/role/listar/${role}`)
  console.log(result)
}

  • But when I go use it to check if it is true or false, it does not understand on account of async and await

  • @Gustavohenrique I don’t know if I understand what you mean, but I’ll change the example considering that your API returns a string with the user’s role

  • Yes, my API returns a JSON with the scroll, so I make a comparison to see if and admin or not.

In addition to what Matheus said, it is necessary to return some function value isAdmin().

For example, if your api returns true or false on request, just use async/await, store the value in a variable, for example result and soon after returning this variable return result.

That way you can use her isAdmin() in a if for example, because when it is executed, it will return a value true or false.
