Authentication related routing logics for an app like this:
This module helps managing the routing based on if the authentication token is available, if the user data has been loaded, and if any of these requests fail. The authentication token is stored in a configurable localStorage variable.
npm install
npm run build
npm start
There are 3 base routes of you application
You have an "API service" with 3 methods (called login/logout/initialRequest) that return promises
Example of using module
example
code for a complete example of how to use this module.apiService
with the three functions login
, logout
, and makeInitialRequest
, which all return a promise. The function makeInitialRequest
handles routing to authenticate
route or logged-in
route based on if initial request succeeds or not.co-auther.provider.ts
which registers apiService
, the three routes, and initializes coAuther
itself.coAutherProvider
in your main.ts
file.co-auther.guard.ts
that makes use of coAuther
to decide which routes are accepted based on the current state of authentication and initial request(s). CoAutherGuard handles routing to authenticate
route if you're not currently authenticated.When writing the error handling in the apiService you will want to use the .catch() of the promises. The problem is that once you've caught a rejected promise, it will bubble up as a resolved promise, so the parent will get a .then(). You can fix it by creating a new promise in your apiService and "rethrow" the error. In the file "example-common/api-service.ts" there is an example of this for the "initialRequest" function.
let apiService = {
makeInitialRequest () {
return new Promise((resolve, reject) => {
return myRequest
.then((data) => {
this.router.navigate(['logged-in'])
resolve(data)
})
.catch((err) => {
localStorage.remove('authData')
this.router.navigate(['authenticate'])
reject(err)
})
})
}
}
