What is the process for establishing a global variable in Angular? I have established a variable within a service, entered a value in the login component, and attempted to access this variable from another component. However, I noticed that the value reset itself in the service. What adjustments or additions should be made to resolve this issue?
In order to ensure the service operates as intended, it should be offered exclusively in the highest level module. This will allow it to function as a singleton, preventing multiple instances from being created and thus avoiding any issues with values resetting.
It seems that the service is currently being provided in each individual component, resulting in separate instances being created for each one.
If you're looking to persist data between page reloads, you can also consider using the localStorage functionality provided by the browser. Depending on your specific requirements, either approach mentioned could be more suitable for your needs.
Another option is to create a service with simple code like the following (to be included in a service file):
saveItemOnStorage(item, key) {
localStorage.setItem(key, JSON.stringify(item));
}
removeItemFromStorage(key){
localStorage.removeItem(key);
}
getItemFromStorage(key) {
return JSON.parse(localStorage.getItem(key));
}
