With the ongoing authority arrival of Angular 2, it's a
decent time to get up to speed on a portion of the most significant changes.
One thing that is changed a ton is the Angular 2
router, which was supplanted in the number one spot up to the last discharge.
I'll demonstrate to you proper methodologies to make course setups and how to
utilise them in an app. You'll find out about primary routes, diverting, and
trump card routes. At that point, you'll perceive how to utilise a mandate to
design your app segment to show the routes.
The article pursues on from past exercises in the course.
However, you ought to have the capacity to pursue the strategies we utilise.
You can discover the source records for the entire venture on GitHub.
Step by step
instructions to Create Routes in Angular 2:
Why Use Routing?
It is conceivable to assemble a full app in Angular 2
without directing. So on the off chance that we can do this, for what reason do
we require addressing by any stretch of the imagination?
The fundamental reason is that on the off chance that we
don't utilise steering, our app will depend exclusively on the route through
program control. We should change out components dependent on client
collaboration, for example, when they tap on something.
With steering, we will have the capacity to explore by
exchanging URLs. All components will guide to a course, enabling us to move
around our app effectively.
Step by step
instructions to set Up Routing:
To start with, with the end goal to make steering work, we
have to include a base href in the leader of our index.html
document.
Already, we would design our routes within the part that
hosts them. For this situation, this would imply that we add our course configs
to our app.component record. With the new router, it is recommended that we
make our course arrangement in a different document.
app.routes.ts :
So how about we make a document called app.routes.ts in the
base of the app envelope. The main things we will add to this document are the
imports.
In the first place, get provide router or RouterConfig from
the Angular router. At that point import the About, Error, and Home components
from the pages envelope. We have to import these with the goal that we can
course these components.
Here we are utilising a const assertion. This is one of the
manners in which we can announce a variable in TypeScript, and it represents
esteem that can't be changed. For this situation, we are utilising it to hold
our RouterConfig.
Presently, the main thing we will include is a divert. In a
minute, we will consist of a trump card course for our error page. This without
anyone else will cause our app to begin from the error page. The reason is that
when our app starts, it doesn't have a course. Subsequently, we have to
determine a part as the default course.
We could without much of a stretch add the part we need to
begin our app to the vacant course; however, the proposed approach to deal with
this is with a divert. The diver needs to start things out, or it won't work
appropriately.
First, we have our way, or, in other words, a course. This
is the course our app will dispatch with. At that point, we have our divert,
which will change our way to home when it experiences a vacant course. From
that point onward, we have our path match. I won't expound but to state that
this makes the unfilled course coordinate the divert.
At that point, we have our course that points at the
AboutComponent. The way is set to 'about', or, in other words, will find in the
location bar when we explore this course. The part that will be explored to is
the AboutComponent. From that point forward, we have the home component. The
way is 'home', and the segment to dispatch is the home component.
This is the course that we will explore to from the divert.
At that point, the last session we will include is a trump card course. This
will coordinate any routes that we have characterised. This is likewise why we
added the divert. If we didn't, our app would begin at this course since we
start from a path that isn't characterised, an unfilled route.
In the wake of including the divert, any course that we
compose that doesn't exist will get our error page. At that point, we send out
another const utilising the given router technique from the Angular router. We
use the routes that we arrange with this strategy. When we do that, our routes
are done. The exact opposite thing we need to do is add directing to our app.
main.ts:
Go to the main.ts record. The principal thing we will do in this
document is import myRouterProviders from the app routes record that we made.
At that point, we need to add it to our bootstrap work. Including them here has
the advantage of making the routes accessible to the majority of the components
in our app.
