The following example handles server and connectivity errors for javascript fetch requests.
function handleErrors(response) { if (!response.ok) throw new Error(response.status) return response } fetch('https://jsonplaceholder.typicode.com/todos/1') // handle network err/success .then(handleErrors) // use response of network on fetch Promise resolve .then(response => console.log("ok")) // handle fetch Promise error .catch(error => console.log('found an error: ', error)) handleErrors can be updated for handling different types of errors in different ways. This function is called whenever we get a response from the server (successful or failed).
Password forms are challenging for users because we often ask them to enter complex strings which they are usually not allowed to see. Additionally, these strings have to meet different criteria – like having upper and lower case characters, numbers and so on – to keep our applications secure.
In this post, we are going to add visual queues to a form that will allow users to get a better experience with passwords.
