I have a file system like this
Pages
secure/
_middleware.ts
protectedResource.tsx
_app.tsx
_document.tsx
index.tsx
I have next configured like this
module.exports = {
...
async rewrites() {
return [
{
source: '/protectedResource',
destination: '/secure/protectedResource'
}
]
}
}
The rewrite works correctly, when accessing http://localhost:3000/protectedResource the user sees the correct route. The middleware from the 'secure' directory, however, is not invoked during the request pipeline. Aside from moving the middleware to the pages directory, how can I resolve this?
I'm moving from a wordpress site to a new, shiny nextjs site. However, I have hundreds of redirects and I don't want to put them all in the nextjs config file. I like things clean and tidy. I searched around for awhile and didn't find any results on how to do this. Any suggestions?
You need to import it via require, tho remember that u also need to export it as module, so ex.:
const redirectsArray = [
{ source: "/about", destination: "/", permanent: true },
];
async function redirects() {
return redirectsArray;
}
module.exports = {
redirects,
};
and then
const { redirects } = require("./redirects.js");
I got it working while module exporting it as an array instead of an object in the redirects.js
module.exports = redirects
And then add it to the next.config.js like so
async redirects() {
return redirects
}
I have a NextJS app and am using Storybook to develop my components.
After looking through all the NextJS routing documentation, I can't find a way to route to my storybook from within NextJS. Only access pages within the /pages directory.
What I would like to do it to have my StoryBook available at /styleguide from within my Next app thought all environments.
Is someone able to help?
Short answer: No, you can not do that.
But you can always redirect the url /styleguide to another domain where Storybook is running, for example styleguide.example.com. Here, an example based on the official documentation:
// next.config.js
module.exports = {
async redirects() {
return [
{
source: '/styleguide',
destination: 'https://styleguide.example.com',
permanent: true,
},
]
},
}
If your URL's would have any parameters for it's origin that you would want to append to the redirects destination, NextJS provides a feature to do just that.
// next.config.js
module.exports = {
async redirects() {
return [
{
source: '/styleguide/:pageId/:slug',
destination: 'https://styleguide.example.com/:pageId/:slug',
permanent: true,
},
]
},
}
I try to build dynamically routes from angular2 (fetch route config from server), after that I parse it and generate instruction for component route (I have parent routes config and child into different components, because I don`t know how define route for child component into one main.app.ts file).
The problem is when app started and try to create routes config and routeGenerator is not build routes yet (async delay) cant parse routes data (because async delay, so routesData undefined now) and app is crashig. I dont know what to do with this. Looking for lifecycle hood (some like - #Angular2BeforeAppStarted ) but found nothing.
import {Component, Input, OnChanges} from 'angular2/core';
import {RouteConfig, RouterOutlet, ROUTER_DIRECTIVES, Router} from 'angular2/router';
/* ------- !Angular 2 native components ---------*/
import {routeGenInstance} from '../../config/routes/patient_routes';
protected const BUILT_MODULE_PATH: string = '/built/modules/patients/';
#Component({
template: `
<router-outlet ></router-outlet>
`,
directives: [RouterOutlet, ROUTER_DIRECTIVES]
})
#RouteConfig(routeGenInstance.getRouteDefinitions())
export class PatientsComponent {
#Input();
constructor() {}
}
Also i try to update routes in the same way (but app is crashed immediately because my Navigation link in navigation component is not have some correct link way)
import {RouteConfig, RouterOutlet, ROUTER_DIRECTIVES, Router} from 'angular2/router';
constructor(
private router: Router
) {
router.config([
routeGenInstance.getRoutesDefinition()
])
}
my route definitions use Async loader so they are correct and work whithout async delay. I don`t know how to make angular wait for my routes definitions and thet start to run the app.
Please, help me. Thanks.
UPD:
#Thierry many thanks for your help again. You are awesome my friend and mentor. One last question (last). Can you tell me how I can define routeConfig into one app file with child subrouting definition?
Its mean. I have main level routes into app files
{
path: '/',
name: 'Dashboard',
component: DashboardComponent,
useAsDefault: true
},
{
path: '/patients/...',
name: 'Patients',
component: PatientsComponent
},
and patient sub routes into patientsComponent (#RouteConfig)
{
path: '/', // root is appRoot/patients/...
name: 'PatientsList', component...},
{
"name": "Chart",
"path": "/chart/:id", component...
},
How to define this route config only into one app.file ? (How to configure route with sub routing in one file)?
An option could be to get your configuration before bootstrapping your application.
var injector = Injector.resolveAndCreate([HTTP_PROVIDERS]);
var http = injector.get(Http);
http.get('routes.json').map(res => res.json())
.subscribe(data => {
bootstrap(AppComponent, [
HTTP_PROVIDERS
provide('routesConfig', { useValue: data })
]);
});
Then you can have access the routes configuration by dependency injection and in a synchronous way:
#Component({
(...)
})
export class AppComponent {
constructor(#Inject('routesConfig') private routesConfig, private router:Router) {
// Configure here your routes
}
}
These two questions could help you:

angular2 bootstrap with data from ajax call(s)
Edit
You can leverage the Observable.forkJoin method to load your route configuration from different requests:
var injector = Injector.resolveAndCreate([HTTP_PROVIDERS]);
var http = injector.get(Http);
Observable.forkJoin([
http.get('mainRoutes.json'),
http.get('childRoutes.json')
])
.map(responses => {
return {
main: res[0].json(),
children: res[1].json()
};
})
.subscribe(data => {
bootstrap(AppComponent, [
HTTP_PROVIDERS
provide('routesConfig', { useValue: data })
]);
});
Edit1
I think that you could try something like that:
[
{
path: '/patients/...',
name: 'Patients',
component: PatientsComponent,
childRoutes: [
{
path: '/', // root is appRoot/patients/...
name: 'PatientsList', component...
},
(...)
]
}
]
But you need to split the content to get different elements according to the hints you want to handle:
one for the root:
[
{
path: '/patients/...',
name: 'Patients',
component: PatientsComponent
}
]
several for children. For example for patients:
[
{
path: '/', // root is appRoot/patients/...
name: 'PatientsList', component...
},
(...)
]
In the new router (>= RC.3) https://angular.io/docs/js/latest/api/router/index/Router-class.html#!#resetConfig-anchor resetConfig can be used
router.resetConfig([
{ path: 'team/:id', component: TeamCmp, children: [
{ path: 'simple', component: SimpleCmp },
{ path: 'user/:name', component: UserCmp }
] }
]);
See also https://github.com/angular/angular/issues/9472#issuecomment-229230093
You can load components asynchronously by providing a SystemJsComponentResolver.
Right now, you can load routes asynchronously and imperatively update the configuration using resetConfig.
Once AppModules are in master, we will utilize those to implement async loading of subconfigs.
https://github.com/angular/angular/issues/11437#issuecomment-245995186 provides an RC.6 Plunker
Check this:
DynamicalAsyncRouter
https://github.com/Longfld/DynamicalAsyncRouter
Using Observables/Promises to provide route translations is not a reliable solution, hence the Angular router expects Route[] or Routes, but an HTTP request can only return an Observable/Promise.
The Angular app gets initialized, but the retrieval process of route translations still goes on using Observables/Promises.
As Thierry Templier said, to get your configuration before bootstrapping your application would solve the problem.
Also, check the #ngx-i18n-router/core on github.
Angular 2 beta uses html5 routing by default.
However, when you go to a component and the route changes (eg http://localhost:5000/aboutus) and you reload/refresh the page, nothing is loaded.
The issue has been raised in this post also.
Most of the answers say that if we are going to pursue HTML5 routing in angular 2, then this issue of routing should be taken care of in server-side. More discussion here.
I am not sure how to handle this issue using the asp.net server environment.
Any angular 2 devs out there who also uses asp.net and encounters this issue?
PS. I'm using ASP.NET 5. My Angular 2 routes are using MVC routes.
The problem you're seeing has to do with the difference between Angular routing on the client and MVC server-side routing. You are actually getting a 404 Page Not Found error because the server does not have a Controller and Action for that route. I suspect you are not handling errors which is why it appears as if nothing happens.
When you reload http://localhost:5000/aboutus or if you were to try to link to that URL directly from a shortcut or by typing it into the address bar (deep linking), it sends a request to the server. ASP.NET MVC will try to resolve that route and in your case it will try to load the aboutusController and run the Index action. Of course, that's not what you want, because your aboutus route is an Angular component.
What you should do is create a way for the ASP.NET MVC router to pass URLs that should be resolved by Angular back to the client.
In your Startup.cs file, in the Configure() method, add an "spa-fallback" route to the existing routes:
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
// when the user types in a link handled by client side routing to the address bar
// or refreshes the page, that triggers the server routing. The server should pass
// that onto the client, so Angular can handle the route
routes.MapRoute(
name: "spa-fallback",
template: "{*url}",
defaults: new { controller = "Home", action = "Index" }
);
});
By creating a catch-all route that points to the Controller and View that ultimately loads your Angular app, this will allow URLs that the server does not handle to be passed onto the client for proper routing.
In your Startup.cs add this to the Configure method. This must be before other app statements.
app.Use(async (context, next) => {
await next();
if (context.Response.StatusCode == 404 && !Path.HasExtension(context.Request.Path.Value)) {
context.Request.Path = "/index.html"; // Put your Angular root page here
await next();
}
});
My favorite solution is to add the following code to Global.asax.cs which very smoothly and reliably takes care of the issue:
private const string RootUrl = "~/Home/Index";
// You can replace "~Home/Index" with whatever holds your app selector (<my-app></my-app>)
// such as RootUrl="index.html" or any controller action or browsable route
protected void Application_BeginRequest(Object sender, EventArgs e)
{
// Gets incoming request path
var path = Request.Url.AbsolutePath;
// To allow access to api via url during testing (if you're using api controllers) - you may want to remove this in production unless you wish to grant direct access to api calls from client...
var isApi = path.StartsWith("/api", StringComparison.InvariantCultureIgnoreCase);
// To allow access to my .net MVCController for login
var isAccount = path.StartsWith("/account", StringComparison.InvariantCultureIgnoreCase);
if (isApi || isAccount)
{
return;
}
// Redirects to the RootUrl you specified above if the server can't find anything else
if (!System.IO.File.Exists(Context.Server.MapPath(path)))
Context.RewritePath(RootUrl);
}
You need use this routing in ASP.NET MVC
app.UseMvc(routes =>
{
routes.MapRoute("Default", "{*url}", new { #controller = "App", #action = "Index" });
});
Then you need set up SystemJS with basePath options
The feature you're looking for is URL rewrite. There are two possible ways to handle it. The classic way is to let IIS do the work, as described here:
https://stackoverflow.com/a/25955654/3207433
If you don't want to depend on IIS, you can instead handle this in the ASP.NET 5 middleware, as shown in my answer here:
https://stackoverflow.com/a/34882405/3207433
I'm not having any luck getting
routes.MapRoute("Default", "{*url}",
new { #controller = "App", #action = "RedirectIndex" });
to work. I still get a 404 with any client side route.
Update:
Figured out why the catch-all route wasn't working: I had an attribute route defined ([Route("api/RedirectIndex")]) and while the plain route can be directly accessed with the fallback route it didn't fire. Removing the attribute route made it work.
Another solution that seems to work just as easy as the catch-all route handler is to just create a custom handler that fires at the end of the middleware pipeline in Configure():
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
//handle client side routes
app.Run( async (context) =>
{
context.Response.ContentType = "text/html";
await context.Response.SendFileAsync(Path.Combine(env.WebRootPath,"index.html"));
});
This basically ends up being the catch-all route that simply sends index.html out over the existing URL request if there was no other handler that picked up the request.
This works nicely even in combination with IIS Rewrite rules (in which case the above just won't ever get fired.
Wrote up a blog post on this topic:
Handling HTML5 Client Route Fallbacks in ASP.NET Core
Here are two more options for solving this problem. You can either add the hash location strategy to your app module.
import { LocationStrategy, HashLocationStrategy } from '#angular/common';
#NgModule({
imports: [.... ],
declarations: [...],
bootstrap: [AppComponent],
providers: [
{
provide: LocationStrategy,
useClass: HashLocationStrategy
}
]
})
export class AppModule { }
This option will only work for the parts of your Angular2 app that live on the Home ASP Controller
Your second option is to add routes to your ASP Controller that match your Angular 2 app routes and return the "Index" View
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
[ActionName("Angular-Route1")]
public IActionResult AngularRoute1()
{
return View("Index");
}
public IActionResult Route2()
{
return View("Index");
}
}
Did you use:
directives: [RouterOutlet, RouterLink] in the component.
apply the #ZOXEXIVO's solution then, in your _Layout.cshtml add this:
<head>
<base href="/"/>
.....
</had>
You can use both the routing
when you call Home/Index from angular routing.
write
Home/Index.cshtml
<my-app></my-app>
app.routing.ts
const routes: Routes = [
{ path: '', redirectTo: '/Home/Index', pathMatch: 'full' },
{ path: 'Home/Index', component: DashboardComponent }
]
So When URL will be Home/Index
will load the component of active url so it will load dashboard component.
The above selected solution did not work for me I also got 404 after following all the comments to the T. I am using an angular5 app in an MVC5 app. I use the default index landing page as the start for the angular5. My angular app is in a folder named mvcroot/ClientApp/ but on ng build it puts the distributed files in mvcroot/Dist/ by altering one setting in the .angular-cli.json file with "outDir": "../Dist"
This solution did work though.
This way only routes in the Dist directory get the fall over. Now you can hit refresh every time and exact route for the angular5 app reloads while staying on the correct component. Be sure to put the catch all first. On a side note, if using a token auth in your angular5, save the token to window.localStorage (or some other mechanism outside your angular5 app) as hitting refresh will wipe out all memory where you you maybe storing your token in a global variable. This keeps the user from having to login again if they refresh.
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Catch All",
"dist/{*url}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional });
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
