All other projects deployed successfully in the past? Trying to solve this, but i think ill have to back to prior cli version. I still trying! It use to be easy not sure what there doing with the CLI?

In any case, check if your Firebase deployments are exhibiting the same behavior. I can probably whip up an example repo if it's useful. I am experiencing the same issue. I deploy my static website to firebase but any file inside public folder like images or CSS are displayed. I remove the redirection from firebase. But, why static files are not deployed to firebase? Same issue here when trying to ng build --prod on my server.We currently have the default Bulma logo in our header.

This won't be good long term because if Bulma ever decided to change that URL, then our app's logo would stop working. It's also a better idea to store this within our project folder so that all assets are served from our same domain. Less round trips means better performance and Google PageSpeed score. Remember when we used the npm run build or ng build --prod command?

Angular CLI moved all of our assets into the dist folder. It will do the same when it sees that there are images inside the assets folder. All we have to do is reference these images in our templates with a path that starts inside the src folder. The assets folder that the Angular CLI generated for us is the perfect place to use for storing images.

Go ahead and save that to our assets folder inside of an img folder. I've named mine angular-logo. Let's also change the color of our header to be a darker color. Our entire assets folder has been moved over to the dist folder now! The path will also work since we referenced it from within the src folder.

Now it's just referencing from within the dist folder. Like this article? Follow chrisoncode on Twitter. Code Demo. Let's go grab the Angular logo from angular. Next Lesson: Creating the Home Page.When you are handling millions of images on your website or mobile application, it is quite possible that over a period of time, a few images may cease to exist.

And when you try to deliver those images on your applications, the users end up seeing a broken image like the one below. Definitely, this is not something that you would want showing up on your application.

There are a few ways on how you can fix this broken image problem to maintain the UX standards of your application. If an image does not exist, then it should be removed from the database.

Better Broken Image Handling

An image URL that is incorrect or points to an image that no longer exists, is most likely a data issue. So the first thing that you can do to counter the broken image problem is to periodically check all images for sanity.

If yes, then the image stays in your database, else you can discard the image. Advantages — Solves the problem at the root level. One-time effort in writing the script.

Disadvantages — Lengthy execution times nearly impossible for millions of images, waste of network bandwidth and cannot catch errors for the time between two consecutive runs of the cleanup task.

If an image does not exist, we can replace it with a new one. Another way to handle this issue is by listening to the error event that gets fired when the image fails to load.

If the original image fails to load, then it is replaced by the image mentioned in the onerror attribute handler. Similar handling can be done in mobile apps as well. Advantages — Can handle data issues in real-time, no need for periodic checks. Problems may continue in older versions of your website or application that cannot be updated with the new code. Different code for different platforms.

If the image does not exist, then the server should not send the error at all. Instead, the server itself could replace it with a default image, correct the HTTP status code and then send it to the browser or the application.

Advantages— Works in real time without any periodic checks. No handling needed on any application or any version of any application.

Works for all kinds of images. Disadvantages — You need to build a server that can handle this rerouting for you. To give an example.

The default image is specified using the di- parameter in the URL. In this case, the default image is from a cafe. Being a URL-transformation, this gives you the flexibility to specify a different default image for different kinds of images without having to write any code to handle the error cases. You can read more about handling of non-existent images or default images using ImageKit here.

Default images sent instead of a non-existent image should not be cached at all or if it is cached, then the cache duration should be small, preferably a few hours. When this happens, then the correct image would start getting delivered to the users automatically.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

When your angular app is not working and all it gives you are some cryptic red lines in a console.

Especially when you are a beginner, these problems can turn the development process with angular into a real pain. But trust me, it does not have to be painful. In fact, I think angular development is one of the smoothest development experience I had so far. All you need to do is avoid some very common mistakes, almost every angular developer had to deal with.

We will take a closer look at each of 11 mistakes. I will explain to you, why it is actually a mistake and point you in the right direction with at least one possible solution.

Probably the most common mistakes, beginners make, is not to import the required modules. Because they don't even know about them. Of course, they don't. Getting an overview of the angular framework takes some time.

Unfortunately, that often results in mysteriously not working angular applications. The errors you get look something like this:. This error indicates, that the angular Forms Module has not been imported into your module. This error tells you, that you have not imported the angular HttpClient Module into your root module. To resolve the problem, you need to import the missing module into your module.

Most of the cases, that module would be the AppModule in your app directory. Only import the modules you really need! Importing unnecessarily module bloats your application size significantly. This advice does not only apply to framework angular modules. It also applies to any angular module you might want to use, including third-party ones. It is good practice for third party libraries to split up in as many modules as possible, to keep the size of your application small.

With Angular Materialfor example, you have to import a module, for every component you use. With the help of the ViewChild decorator, angular makes it very easy to reference specific child elements html nodes or components of your component. All you need to do is to add a reference identifier to the node or component inside of your template.

Just add a followed by a name beside the nodes attributes. We can now reference that element from our component. If it is a component, we can call its public methods and access its properties. If it is a plain HTML element, we can change its style, its attributes or its children. Angular automatically assigns the reference to a property of our component, if we decorate that property with the ViewChild decorator. Make sure, to pass the reference name to the decorator. For example ViewChild 'myDiv'.

Why shouldn't it? There are multiple reasons why the element you are referencing could not actually exist. The most common reason, is, that the browser has not finished creating it and has not yet added it to the DOM. If you try to use it before it has been added, it will not work and crash your app. If you are familiar with JavaScript in general, you have probably stumbled across that problem, as it is not specific to angular.

One example of accessing the DOM when it does not exist is in the constructor of the component.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
