I'm following this tutorial: https://medium.com/@blacksonic86/authentication-in-angular-2-958052c64492 about authentication in Angular2.
I've the issue with this part:
import localStorage from 'localStorage';
I've read somewhere else that I should use this library https://github.com/marcj/angular2-localstorage to access local storage in HTML5. Is it really the only option? Can I access HTML5 local storage from angular2 without using extra modules?
You can use localStorage
directly in your service without import localStorage from 'localStorage';
.
You should use directly localStorage
, as mentioned by other here, it is a builtin browser features ( supported browser ).
Additionally I am adding below few examples on how to add an entry in it (they work both in the same way).
localStorage.colorSetting = '#a4509b'; // dot notation
localStorage['colorSetting'] = '#a4509b'; // bracket notation
localStorage.setItem('colorSetting', '#a4509b');
As a note, angular2-localstorage
works on top of native localStorage
and provide a "convenient" way to save and restore automatically a variable state in your directive.
I noticed that the local storage project is seeking someone to takeover and is not currently being maintained. So I am not going to use it until then. I was able to find the a fix in my tsconfig.json file.
In the property lib you can simply add dom
"lib": [
"es2016",
"dom"
]
This is supported in the compiler options https://www.typescriptlang.org/docs/handbook/compiler-options.html .
I had to restart visual studio code for this to remove the errors.
