Dynamic Routing with Route Parameters — Let’s Learn Adonis 5, Lesson 2.1

Route parameters give us a way to add dynamic routes to our route definitions so that we don’t have to define a route for each identity that’s within our database.
For example, without route parameters, in order to have a route for posts with an id of 1, 2, and 3, we'd need to manually define the same route for each individual id. That quickly becomes a scalability issue, as you can see below.
Route.get('/posts/1', () => 'get post 1')
Route.get('/posts/2', () => 'get post 2')
Route.get('/posts/3', () => 'get post 3')Route.put('/posts/1', () => 'get post 1')
Route.put('/posts/2', () => 'get post 2')
Route.put('/posts/3', () => 'get post 3')Route.delete('/posts/1', () => 'get post 1')
Route.delete('/posts/2', () => 'get post 2')
Route.delete('/posts/3', () => 'get post 3')
With route parameters, we can make the id portion of the URL dynamic so that we only need to define the route once.
