When I deploy my Nextjs app I get a buid err. Vercel doesn`t see nested pages. How can I override it, maybe it is posible in vercel.json?
Building logs
Project structure
I tried this, but it`s breaks everything
module.exports = {
pageExtensions: ['page.tsx', 'page.ts', 'page.jsx', 'page.js']
}
Could you try moving your components outside pages folder as Next.js has a file-system based router built on the concept of pages.
Hope you should be using export default instead of export inside index.tsx for exporting your component.
I'm trying to implement Esri ArcGIS JS in Lightning Web Component. While using ArcGIS JS, the sample code uses require function to load modules. In order to do that I'm trying to use require.js. I downloaded it from here (Require.js). And then uploaded to my sandbox as static resource. I'm trying to use that static resource in my Lightning Web Component. I also added the script tag for the ArcGIS Javascript API in my Experience Cloud site's header as
<script src="https://js.arcgis.com/4.24"></script>
Lightning Web Component:
import { LightningElement, track } from 'lwc';
import { loadScript } from 'lightning/platformResourceLoader';
import requireJS from '#salesforce/resourceUrl/requireJS';
export default class TestMap extends LightningElement {
renderedCallback() {
loadScript(this, requireJS).then(() => {
console.log('requireJS loaded');
require([
"esri/geometry/Extent"
], (
Extent
) => {
var initExtent = new Extent({
xmin: -15884312,
ymin: 1634835,
xmax: -6278767,
ymax: 7505198,
spatialReference: 102100
});
});
}).catch(exception => {
console.log(exception);
});
}
}
My problem right now, eventhough I can see in the Network tab that the require.js is loaded from static resource, require function cannot be found.
Exception message catched
I'm not sure where is the issue since this is how I loaded my all javascript files before.
I was expecting to see the the require function is working after the require.js script loaded from Static Resource.
This one is a bit tricky, I will try to guide you as much as I can.
First, don't put the script tag in your website header. This is a last chance solution, we'll keep it if nothing else work.
Second, requireJS is not compatible with LWC (or Locker Service to be precise). So you can forget it. loadScript is in someways similar.
Now the solution, usually I download the whole from a CDN and host it as a static resource. Then you can load it via loadScript and use it as per the documentation.
In case the library is really small, it could be created as a LWC and then be imported but usually libraries are too heavy regarding Salesforce limit.
Looking at the library, it seems that they do not provide any compiled full version (which is probably huge). In this case I would recommend to make a custom build locally containing only the necessary pieces of code and then uploading as a static resource. Unfortunately I can't help on this part as I still didn't do it myself yet.
Feel free to comment and I will improve my answer is it's unclear.
I have a requirement to create scanning functionality using Node js API with existing scanning software in PC. so How can I achieve that type of functionality using Node js and Angular-8.
I have already checked Dynam Twain SDK but it is available only for 30 day trail.
Thanks to all for your help.
Your question is a little confusing. Indeed, Dynamic Web Twain can simply run a web server with node.js to load web applications. But since you already mentioned Angular-8, you may want to use Node.js API to call Dynamic Web Twain to scan pages, right?
Here is a sample shows how to integrate Dynamic Web TWAIN JavaScript library into an Angular project.
export class AppComponent implements OnInit {
title = 'angular-cli-application';
DWObject: WebTwain;
selectSources: HTMLSelectElement;
ngOnInit() {
Dynamsoft.WebTwainEnv.AutoLoad = false;
Dynamsoft.WebTwainEnv.Containers = [{ ContainerId: 'dwtcontrolContainer', Width: '583px', Height: '513px' }];
Dynamsoft.WebTwainEnv.RegisterEvent('OnWebTwainReady', () => { this.Dynamsoft_OnReady(); });
Dynamsoft.WebTwainEnv.Trial = true;
Dynamsoft.WebTwainEnv.ProductKey = "A-Valid-Product-Key";
//Dynamsoft.WebTwainEnv.ResourcesPath = "https://tst.dynamsoft.com/libs/dwt/15.2";
Dynamsoft.WebTwainEnv.Load();
}
You can find the code here.
And if you want to scan documents with Node.js API on the server-side, you can refer to the code here.
I have a couple of (software-)architecture questions regarding a migration from Grails (REST-API, parts of AngularJS, MongoDB, Tomcat, Spock, several plugins) to Node.js + Angular.js.
I probably have to explain the structure of the Grails project fist, so here we go:
There is a main Grails application (beside a couple of other applications), which is built on several plugins. Each of these plugins is able to get executed by itself - that means it has its own UI, individual templates, services, controllers, routes, tests etc. It is also hosted on different repositories.
This is done by the Grails plugin mechanisms. The benefits are less testing-efforts, less compiling time, modularization, single responsibilities and so on.
But still, the time to compile and test are too expensive. Also I don't like the fact that the API delivers parts of the templates/views. I would like to have the backend APIs "just to be backend APIs" and the frontend "just to be the frontend".
So each AngularJS application/plugin will provide its own view, routes, service etc. But they might also depend on other plugins.
So what I would like to achieve is as follow:
One main AngularJS application, which includes several plugins (a plugin can be something like a report-generator, a guestbook or whatsoever, speaking of a single independent part of an application, either with a specific route, or just a small part of the page).
Each plugin must be a stand-alone AngularJS application (probably executable during development via grunt or so). So that the UI developer does not need to start the whole backend application, further that we may run functional tests only with JavaScript
Communication only via REST, The frontend must retrieve all it's data from the APIs
Each plugin must be testable on its own
A Plugin might require other plugins to work
The main index.html (and app.js?) might be provided by a Nginx server, which is decoupled from the rest of the backend (API)
Though I have a specific picture in my head, I am struggling in how to setup this architecture.
In Grails the plugin mechanisms are somehow merging the plugin dependant settings (like URL mappings, dependencies, etc) to the main application in which they get included/injected - this is what I want to achieve with AngularJS as well. So:
Are there some kind of same mechanisms for AngularJS?
How may I provide/merge the routes of each plugin into the main application?
How can I declare application- and plugin-dependencies?
What tools might be usefull for the build process?
How to establish lazy-retrievments of the plugin-resources (css/less files, views, services etc)?
Prevent the application to provide all resources of the plugins on startup (I guess the routes are required on startup though)
Since this is not just a how-to-do-this-or-that question I excuse myself if I am missing important parts or if some parts are not clear enough. Just ask me and I will answer each question in depths.
** This answer is incomplete **
I want to make sure I understand you before I dig into this.
Here's a quick implementation of a Loader module to manage lazy loading (plugins, vendor assets, admin stuff etc).
Does this help?
angular.module('Bizcoin.loader')
.service('Loader', Loader);
function Loader($injector, $ocLazyLoad, User) {
var Loader = {
load: load,
get: get,
plugins: {},
flags: {}
};
init();
return Loader;
function init() {
load('vendors');
if (userIsAdmin)
load('admin');
}
function load(plugin) {
Loader.plugins[plugin] = Loader[plugin] || $ocLazyLoad.load('path/to/'+plugin+'.js');
return Loader.plugins[plugin].then(setFlag);
function setFlag() {
return Loader.flags[plugin] = true;
}
}
function get(plugin) {
return load(plugin).then(function() {
return $injector.get(plugin);
});
}
}
I work on an large .Net/AngularJS application that is composed of 20+, independent, Areas (or modules) and some core functionality common and reused across all Areas.
Let me go into detail on how I do this for my particular case, and it might give some ideas. The fact that I use .Net is irrelevant here, since this can achieve with any framework.
Each Area acts as an independent application that depends only on the core functionality, always present. Each Area has its own ASP.Net MVC route.
Each Area registers with the core application the menu links it wants to provide.
When the customer goes to the application dashboard, only the core part of of the application. When the user clicks on link in the menu, it will navigate to the content provided by one of the Areas, and only the core plus the assets of that Area are loaded.
Lets see how this is done.
In the main page of the application I load the scripts like this:
<script type="text/javascript">
// a JS object with all the necessary app data from the server.
// e.g.: menu data, etc
window.appContext = #Html.Action("ApplicationContext", "Portal"));
</script>
#Scripts.Render("~/bundles/angular-main")
#RenderSection("AngularAreas", required: false)
I make use of dot .Net bundles and sections.
The main (core) AngularJS part of the application consists of angular configuration, internationalization services, global notifications service, reusable UI components, etc. This is loaded is #Scripts.Render("~/bundles/angular-main").
The #RenderSection("AngularAreas", required: false) section will be filled in by each area when the user navigates to that Area.
Lets see some AngularJS code.
Here is part of the main app.ts.
// If user is visiting an Area, the NgModules array will be augmented.
// with the modules the Area wants to provide (to be bootstrapped)
export var LoadNgModules = [
NgModules.Config,
NgModules.Core
];
angular.module(NgModules.Bootstraper, LoadNgModules);
angular.element(document).ready(function () {
angular.bootstrap(document, [NgModules.Bootstraper]);
});
Lets look at an example Area now.
And here is how an Area would supply its assets, to be outputted in #RenderSection("AngularAreas", required: false):
#section AngularAreas {
#Scripts.Render("~/bundles/areas/staff-management")
}
Its a simple bundle containing all the scripts for that Area.
Now, let's see the important part of the AngularJS code for this Area.
var StaffManagementNgModule = 'areas.staff-management';
// Push our self into the modules to be bootstrapped
LoadNgModules.push(StaffManagementNgModule );
// Define the module
angular
.module(StaffManagementNgModule , ['ngRoute', NgModules.Core])
.config([
'$routeProvider', '$locationProvider', ($routeProvider: ng.route.IRouteProvider, $locationProvider) => {
$routeProvider
.when(staff', { template: '<staff></staff>' })
.when('staff/details/:id', { template: '<staff-details></staff-details>' });
}
]);;
That is all, from here the Area is a normal Angular application.
To summarize, we load the main (core) AngularJS functionality and provide the LoadNgModules array that an area can fill with its own modules.
we load the Area scripts and and "our self" to the LoadNgModules array.
finally the run angular.bootstrap.
For completeness, here is a fragment of C# showing how an area would indicate to the main application that it is available
public class ItemManagementModuleRegistration : IModuleRegistration
{
public void Register(ModuleContext moduleContext)
{
string thisAreaName = "Staff";
moduleContext.RegisterMenu(menuContext =>
{
var ItemsMenu = menuContext.Items(thisAreaName);
// add urls and stuff...
});
// register more stuff with the moduleContext
}
}
Using reflection one can easily find what areas are "installed".
These are the main moving parts of the setup.
Each Area can have its own API and tests. It is quite flexible.
Is it possible to somehow override the login method of the Secure.java class of the Secure-Module in Play! Framework, so that another version of the login form is displayed?
In my case, i want to display a mobile version of the login-form if a mobile browser is detected.
I know i should not change the Secure.java class itself, but i don't really see any other solution to this problem.
As discussed in other posts you have the request in your Play! controller. So in this request you could ask which agent is trying to view your website:
String agentInfo = request.headers.get("user-agent");
The you can determine which template will be rendered for this agent:
if (agentType.isWhatEverHeIs) {
renderTemplate("Application\mobileTemplateForBadPractise.html");
} else {
render();
}
But what I would encourage you to do is responsive webdevelopment. Create your templates as smart as possible, let the template and css and javascript do this and keep your business logic in your controller.
You could use the Twitter Bootstrap to achieve this, but there are many more! Like Skeleton.
You even got the request object inside your templates so that you can optionally render things in your template (or not) based on the agent.
Even simpler, simply create/override the secure/login.html template and use responsive design : media queries. No need to change the controller or check agent or whatever.
