Since two days I try to load a template in require.js using the text plugin, but I can't manage that.
define(['jquery', 'text!myView.html'], function ($, myView) {...
Produces the error: XMLHttpRequest cannot load
So I put myView.html to a local Webserver and enabled CORS
define(['jquery', 'text!http://localhost/myView.html'], function ($, myView){...
Produces the error: Uncaught SyntaxError: Unexpected token <
Google told me, I should use the requirejs optimizer, which produces a .js out of my html file. This should solve the problem.
To be honest, I really don't undertand what to write in the build.js.
It's so confusing to me. Here is an example build.js: https://github.com/jrburke/r.js/blob/master/build/example.build.js
The only thing I know is that "optimizeAllPluginResources" option has to be true. But what about all the other options?
build.js:
({
paths: {
myView: "myView.html"
},
optimizeAllPluginResources: true,
name: "myView",
out: "myView.js"})
..doens't work
Let me summarize: I only want to optimize a single html file, to use it my Application, nothing else.
Thanks for help.

I have a nuxt-app, where I have a lot of posts. I recently refactored the project and I won't generate all posts anymore, as it is just taking too much time to do that.
Instead I have a page where I would fetch the matching post content via url query:
www.mypage.com/posts/?post=my-post-slug
Because the content is lying in static json files, for example in:
/static/data/posts/my-post-slug.json
/static/data/posts/my-post-slug_2.json
/static/data/posts/my-post-slug_3.json
/static/data/posts/my-post-slug_n.json
I read the post https://github.com/nuxt/nuxt.js/issues/123
about how to load json in the best way.
I decided to do something like this in the fetch() hook:
// ... simplified code
async fetch() {
let postSlug = this.$route.query.post
const post = this.$axios
.get(`/posts/posts.de.${postSlug}.json`)
.then((data) => {
return data?.data
})
.catch((error) => {
console.error('error: ', error)
const code = parseInt(error.response && error.response.status)
if (code === 404) {
this.$nuxt.error({ statusCode: 404, message: 'Post not found' })
}
})
this.activePost = post?.items?.[0] || false
}
As already said, I do not generate the actual posts, but I generate all post urls in my sitemap.xml.
When running the generate in analyze mode I have now a huuuuge bundle size (app.js), and I can't understand why...
-> Check out the attached image. (Note: app.js has a ridiculous size of 34MB!!!!😕)
I don't understand why all my post jsons appear in the static and the dist part of the bundle???
I don't understand at all why they appear in there. I want them to just lie in the static folder, but not be included in the app bundle.
(you can see that there are files like events.bundle.de.json included. I need those to fetch a list of all posts for example. I do that also within my fetch hook only.
I would be very happy if somebody could point out why those files are included (twice)!
Those files are not included "twice". You need them, so you do have them locally in your static folder.
Meanwhile, you should probably put them inside of your src directory if you don't want/need to have them exposed publicly and benefit from code-splitting thanks to Webpack as explained in the post you've linked (which is still valid even if it's a 2017 one!).
Here, since you're making an axios call and using target: 'static', it will bundle your whole thing to work even without JS and it does that ahead of time. So, in order to have all the possibilities, it includes all in the final bundle I think.
If you want to only load what is needed while not shipping a big static directory, you should import them dynamically. You can use a dynamic import: load only the needed JSON by passing the actual postSlug.
PS: style-wise, prefer using async/await (.then is deprecated) and maybe also $axios.$get.
Although I think #kissu s answer is answering my question in the title, it was not the solution for my problem. For the sake of completeness I will post what I found out after long and many hours of debugging. I still don't quite understand why this even happened, but maybe someone could comment on that as well:
In my nuxt-project I am using a utility file getData.js of which I import a function getDataServer into one of my vuex store modules.
// vuex store module: store/data.js
import { getPreviewData } from '~/api/getData'
The code looks like this:
// getData.js
// Get static JSON file (e.g. basic.de.json or posts.de.1.json)
export function getDataServer(fileProps) {
return require(`~/${fileProps.path}${fileProps.name}.${fileProps.lang}${
fileProps.page ? `.${fileProps.page}` : ''
}.json`)
}
Only by importing and not even by executing that function webpack would bundle EVERY .json file it can find in my root folder into my app.js.
That is why I had a dist folder appearing in my bundle, if not deleted. (The point I talk about in my original question, where I have things included twice).
I even created additional folders and .json files to see, and they were all bundled no matter what.
Only after removing the getData.js from my project my bundle became clean.
I understand that with the require command, webpack cannot tree-shake things, so I would have expected that some code-splitting features would not work, but what I did not expect was that this bit of code would automatically get every .json in my folder...
Does anyone know why importing that function would execute it in a way that acts as a wildcard for all .jsons?
To me it still does not make any sense.
Thanks and cheers.
I have a Blazor Webassembly project with a controller method as follows:
[HttpGet]
public async Task<List<string>> GetStatesForProfile()
{
IConfigurationSection statesSection = configuration.GetSection("SiteSettings:States");
var sections = statesSection.GetChildren();
var states = statesSection.GetChildren().Select(s => s.Key).ToList<string>();
return states;
}
The razor page calls this method:
private async Task<bool> GetStatesModel()
{
try
{
States = await http.GetJsonAsync<List<string>>("api/account/getstatesforprofile");
...
}
catch (Exception ex)
{
Console.WriteLine($"Exception: {ex.Message}, Inner: {ex.InnerException.Message}");
}
I get this Exception:
Exception: '<' is an invalid start of a value.
I read these values from appsettings.json file, And there is no '<' in values.
{
"SiteSettings": {
"States": {
"New York": ["NYC"],
"California": ["Los Angeles", "San Francisco"]
}
}
Also I put a breakpoint in the controller method and it doesn't hit.
What is this error? Is it from parsing json? and how to resolve this?
I had a very similar problem.
In the end it turned out that my browser had cached the HTML error page (I guess I had some problems with the code when I first tried it). And no matter how I tried fixing the code I still only got the error from cache. Clearing my cache also cleared the problem.
It happens when you're trying to access an API that doesn't exist. You have to check your API project connectionstring under AppSettings and make sure it's correct and running. If it's a Blazor project, you can set it as your default project, execute and see if you get a json response.
Most probably the response you are receiving is html instead of actual JSON format for the endpoint you are requesting. Please check that.
An as HTML usually starts with <html> tag, the JSON validator fails on the very first character.
You should also clear any cache, that might be interfering with the returned data. (this has helped people resolve this same issue)
I know this is an old question, but it's one of the top results when Googling the error.
I've just spent more time than I care to admit to tracking down this error. I had a straightforward Blazor hosted app, basically unchanged from the template. It worked just fine when run locally, but when published to my web host API calls failed. I finally figured out that the problem was that I was running the publish from the Client project. When I changed to the Server project it worked properly.
Hopefully my long frustration and slight stupidity will save someone else making a similar mistake.
Seems like your api is not not accessible and its returning error HTML page by default.
You can try below solution:-
I think you are using httpclient to get data to blazor application.
If you have separate projects in solution for blazor and web api,
currently your startup application may set to run blazor project only.
Change startup projects to multiple (blazor and web api app) and give httpClient url in startup of blazor application, as webApi application url, that may solve your issue.
This error indicates a mismatch of the project targeting framework version and installed runtime on the machine. So make sure that the target framework for your project matches an installed runtime - this could be verified by multiple means; one of them is to check out the Individual Components tab of the Visual Studio Installer and lookup the target version.
E.g., there is the TargetFramework attribute in the proj file:
<PropertyGroup>
<TargetFramework>net5.0</TargetFramework>
</PropertyGroup>
Then launch the Visual Studio Installer, click Modify, and visit the Individual Components tab:
Install the missing runtime (.NET 5 Runtime in this case) and you're good to go.
I got the same error. Red herring. use your browser or postman to check your api endpoint is returning the json data and not some HTML. In my case my "api/companytypes" had a typo.
private CompanyType[] companytypesarray;
private List<CompanyType> CompanyTypeList;
private List<CompanyType> CompanyTypeList2;
public async Task<bool> LoadCompanyTypes()
{
//this works
CompanyTypeList = await Http.GetFromJsonAsync<List<CompanyType>>("api/companytype");
//this also works reading the json into an array first
companytypesarray = await Http.GetFromJsonAsync<CompanyType[]>("api/companytype");
CompanyTypeList2 = companytypesarray.ToList();
return true;
}
I know this is an old question, but I had the same problem. It took some searching, but I realized that the return data was in XML instead of JSON.
I'm assuming your "http" variable is of type HttpClient, so here's what I found worked for me.
By setting the "Accept" header to allow only JSON, you avoid a miscommunication between your app and the remote server.
http.DefaultRequestHeaders.Add("Accept", "application/json");
States = await http.GetJsonAsync<List<string>>("api/account/getstatesforprofile");
I had the same issue when passing in an empty string to a controller method. Creating a second controller method that doesn't accept any input variables, and just passing an empty string to the first method helped to fix my problem.
[HttpGet]
[ActionName("GetStuff")]
public async Task<IEnumerable<MyModel>> GetStuff()
{
return await GetStuff("");
}
[HttpGet("{search}")]
[ActionName("GetStuff")]
public async Task<IEnumerable<MyModel>> GetStuff(string search)
{
...
}
Versions of package
Try to update your packages to old or new version. In my case, system.net.http.json is updated from 6.0 to 5.0
Likely you are using an Asp.NetCore hosted WASM application. By default the client's App.razor has something similar to:
<CascadingAuthenticationState>
<Router AppAssembly="#typeof(Program).Assembly">
<Found Context="routeData">
<AuthorizeRouteView DefaultLayout="#typeof(MainLayout)"
RouteData="#routeData">
<NotAuthorized>
<RedirectToLogin />
</NotAuthorized>
<Authorizing>
<Loading Caption="Authorizing..."></Loading>
</Authorizing>
</AuthorizeRouteView>
</Found>
<NotFound>
<LayoutView Layout="#typeof(MainLayout)">
<p>Sorry, there's nothing at this address.</p>
</LayoutView>
</NotFound>
</Router>
</CascadingAuthenticationState>
Herein lies the problem. Since the Client and Server share the same base address, when the application cannot find "api/account/getstatesforprofile" it gives you the client's "Sorry, there's nothing at the address" page. Which is of course HTML.
I have not found the solution to this issue, but I am working on it and will reply once I find an issue.
I was having the same problem,
"JsonReaderException: '<' is an invalid start of a value."
In my case the url for the REST service was wrong.
I was using the URL from the client project. Then I looked at the Swagger screen,
https://localhost:44322/swagger/index.html
and noticed the right URL should start with "44322"...
Corrected, worked.
In my case, I had a comma (,) written mistakenly at the beginning of the appsettings.json file ...
Just check your file and verify
///////
my error details
//////
System.FormatException HResult=0x80131537 Message=Could not parse the JSON file.
Source=Microsoft.Extensions.Configuration.Json StackTrace: at line 16 This exception was originally thrown at this call stack: [External Code] Inner Exception 1: JsonReaderException: ',' is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.
////
For me, most of the time it is the #lauri-peltonen answer above. However, now and again, depending on who wrote the controller I have found that this will work in Swagger but not when you call it via the client (at least in this Blazor project we are on.)
[HttpGet]
[Route("prog-map-formulations")]
public async Task<List<GetProgramMapFormulationsResult>> GetProgramMapFormulations(int formulationId)
{
...
}
It sends the request as:
api/formulation-performance-program-map/analytical-assoc-values?formulationId=1
And I get results in Swagger but failes with the '<' OP error.
When I change ONLY the route to:
[HttpGet]
[Route("prog-map-formulations/{formulationId:int}")]
public async Task<List<GetProgramMapFormulationsResult>> GetProgramMapFormulations(int formulationId)
{
...
}
It sends the request as:
api/formulation-performance-program-map/analytical-assoc-values/1
And this works in both Swagger as well as from the Client side in Blazor.
Of course, once updated, I did have to clear the cache!
If you delete "obj" folder in your directory then clean the solution and rebbuild it the exception will be resolved
In all these, there is two things that was my issue and realized, first off was that Route[("api/controller")] instead of Route[("api/[controller]")], that is missing square brackets. In the second exercise I was doing, with the first experience in mind, was from the name of the database. The database had a dot in the name (Stock.Inventory). When I change the database name to StockInventory it worked. The second one I am not so sure but it worked for me.
I am trying to use JSZip to unzip a JSON file but due to my lack of understanding how JSZip works I get the response in a format that I do not know how to use.
So far this is my code:
this.rest.getFile(this.stlLocation).subscribe(
data => {
let JSONFIle = new JSZIP();
JSONFIle.file(data.url, data._body, {binary : true, compression : 'DEFLATE'});
console.log(JSONFIle);
},
err => {
this.msgs.push({severity: 'error', summary: 'Error Message', detail: err});
}
);
So I download a file using an angular 2 service and I use an observable to get the response. When the data is received I finally call JSZip and try to unzip the file but the result of the operation is an intricate object with my data scattered all over the place and buried inside several layers. All I want is the unzipped JSON file that I can open and process.
Thank you for your help,
Dino
after a bit of reading I have realized I was going on the wrong path. If you are downloading the file to a browser, you shouldn't have to do anything. Browsers add the Accept-Encoding: 'deflate' header automatically; it is both unnecessary and not good practice to do this at a DOM/JS level. If you are using NGINX the following link may help you out:

I am trying to implement Push Notifications on my website (using Pushpad). Therefore I created a "manifest.json" with following content:
{
"gcm_sender_id": "my_gcm_sender_id",
"gcm_user_visible_only": true
}
of course I created a valid GCM-Account and have a sender id
I put the manifest.json into my root directory and I also added this line to my index.php:
<link rel="manifest" href="/manifest.json">
Using Firefox everything works fine and I can send and receive push notifications (so I think the manifest-include works fine), but Chrome won't work...
The console shows following error:
Uncaught (in promise) DOMException: Registration failed - manifest empty or missing
I searched Google for a long time and tried everything I found, but nothing works.
What I tried:
created the manifest.json with "Editor" and saved it as type All Types (so no hidden .txt-file) and also with UTF-8-Encoding.
restarted Chrome
cleared Chrome's cache, history, etc.
I really hope somebody can help me.
For me it was a redirect. The manifest.json must return a 200 status code (must be directly available from the server), without any redirects.
You can check the response via
wget --max-redirect=0 https://example.com/manifest.json
or
curl https://example.com/manifest.json
I faced same issue,added manifest file right after head tag . which worked for me.Cheers!
This may be an issue with your Service Worker scope. I ran into a similar problem when I rearranged my files/directories. Make sure your sw.js is on the same level as your manifest.json, otherwise the service worker won't be able to find your manifest. Try putting them both in the root of your directory. Optionally, you can specify the scope of your service worker by adding it to serviceWorker.register():
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/sw-test/sw.js', {scope: '/sw-test/'})
.then(function(reg) {
// registration worked
console.log('Registration succeeded. Scope is ' + reg.scope);
}).catch(function(error) {
// registration failed
console.log('Registration failed with ' + error);
});
}

Was wondering if your "manifest.json" is public accessible ?
If not maybe you can try to set it public accessible to see if that helps or not.
And it seems that the current chrome, when getting the "manifest.json" won't supply the cookies.
Because I didn't find an answer anywhere out there in the WWW, but managed to get it working after some time I want to provide my solution/answer for other users, who probably have the same problem:
In the file where I inlcuded the Pushpad files I wrote some PHP-Code before the <head>-Tag to include some files, e.g. for database connection. After I moved the PHP-Code below the <head>-Tag everything worked fine.
There seem to be three ways to fix this bug:
a) No redirects for "manifest.json" file.
b) Put a link to this file at the top of the tag.
c) Be sure, that there is no other manifest file before this one, cause it seems that web push script will try to import the first one and return an error due to the wrong data.
I have tried all three and finally forced Chrome to behave.
Adding the following block fixed this for me:
self.addEventListener('push', (event) => {
const title = 'Get Started With Workbox';
const options = {
body: event.data.text()
};
event.waitUntil(self.registration.showNotification(title, options));
});
I am trying to read a JSON file with Meteor. I've seen various answers on stackoverflow but cannot seem to get them to work. I have tried this one which basically says:
Create a file called private/test.json with the following contents:
[{"id":1,"text":"foo"},{"id":2,"text":"bar"}]
Read the file contents when the server starts (server/start.js):
Meteor.startup(function() {
console.log(JSON.parse(Assets.getText('test.json')));
});
However this seemingly very simple example does not log anything to the console. If I trye to store it in a variable instead on console.logging it and then displaying it client side I get
Uncaught ReferenceError: myjson is not defined
where myjson was the variable I stored it in. I have tried reading the JSON client side
Template.hello.events({
'click input': function () {
myjson = JSON.parse(Assets.getText("myfile.json"));
console.log("myjson")
});
}
Which results in:
Uncaught ReferenceError: Assets is not defined
If have tried all of the options described here: Importing a JSON file in Meteor with more or less the same outcome.
Hope someone can help me out
As per the docs, Assets.getText is only available on the server as it's designed to read data in the private directory, to which clients should not have access (thus the name).
If you want to deliver this information to the client, you have two options:
Use Assets.getText exactly as you have done, but inside a method on the server, and call this method from the client to return the results. This seems like the best option to me as you're rationing access to your data via the method, rather than making it completely public.
Put it in the public folder instead and use something like jQuery.getJSON() to read it. This isn't something I've ever done, so I can't provide any further advice, but it looks pretty straightforward.
The server method is OK, just remove the extra semi-colon(;). You need a little more in the client call. The JSON data comes from the callback.
Use this in your click event:
if (typeof console !== 'undefined'){
console.log("You're calling readit");
Meteor.call('readit',function(err,response){
console.log(response);
});
}
Meteor!
