booksearch | A booksearch app UI built with ReactiveSearch | User Interface library

I have tried to create a function which searches for the title in an array of book-objects. For some reason my code doesn't work, I have tried going through each step logically and in my mind it should be working.

I want to make search engine, but after I searched some books, I couldn't search it. It only return zero books.

Hi I am creating an app where a user can search for a book and put it on a shelf depending on which shelf the user clicks on. Currently the user can type a query and many results can get displayed. The user can open a dropdown on a book and click on a shelf (in the dropdown) to select a shelf for that book.

I want to call a method that will update the shelf of a book. It works only if the shelfType is hardcoded however (shelfTypes are 'wantToRead', 'read', 'currentlyReading'). What I want to happen is that the user clicks on a shelf and that shelf is set as the local state variable shelfType in SearchPage. Then once the shelfType changes, the method to update the shelf of a book will run (it makes an API call to a backend).

But for some strange reason I can only update the shelf if I hardcode the shelf type into the update method, not when I use the value of the state shelfType. What am I doing wrong? I hope this question makes sense.

Hi I am creating an app where a user can search for a book and put it on a shelf depending on which shelf the user clicks on. Currently the user can type a query and many results can get displayed. I want the user to a dropdown on a book and click on a shelf (in the dropdown) to select that book and move it to that shelf.

What I trying to do now is retrieve the book object when the user clicks on a dropdown option (which is a shelf). I want to pass this book object into an api call. How would I retrieve the book object when the user clicks on a specific book's dropdown option? I understand that this might involve event bubbling. I hope this question makes sense.

Often I work on Spring Boot Java applications (built with Gradle or Maven) that make network calls to external services (e.g. to external REST-like APIs). When running automated (JUnit) tests, I do not want these calls to happen, even by accident. Calling a real endpoint (even a "dev" environment one designed for testing) could affect external state, cause needless server workload, or unintentionally reveal information to the endpoint. It might also cause the test to inadvertently depend on that external resource being up, leading to build failures if the resource ever goes down while building the project, or when building the project offline.

What should typically happen with these calls is that they should either be mocked out to do nothing or should point to a service on the same machine (e.g. a WireMock endpoint on localhost spun up by the test, or a local Docker container spun up by the test using Testcontainers).

What I tend to in these situations is create a test-specific bean definition profile that overrides all HTTP endpoints with something obviously bogus that is guaranteed not to route somewhere, e.g. http://example.invalid/bookSearch. That way, if a developer misses mocking out or changing the endpoint in a test, it won't call a real one and trigger real side effects.

However, this approach is potentially error prone, and oversights in the implementation or with future changes could cause network calls to still be made. Examples include:

1. A new endpoint could be added by a developer without remembering to or knowing that they needed to override the test route
2. An endpoint could be missed being overridden in the first place
3. A third party library could be making a request that the developer didn't know about or wasn't accounted for

This is mostly a concern with Spring integration tests that spin up some or all of the environment (e.g. using @SpringBootTest or @ExtendWith(SpringExtension.class)). However, this could conceivably apply to a unit test if a component used something as a non-required constructor argument that connected to the network, or if a developer passed in a real network-connecting component where they should have used a mock or something connecting to localhost.

It occurs to me that there might be a more bullet-proof solution to this scenario. For instance, perhaps there is a way to tell the JVM or its underlying HTTP/FTP/etc. libraries to block all external network traffic.

Is there a way to prevent nonlocal network access in Java Spring Boot JUnit tests, or otherwise provide a guarantee that external network endpoints will not be called?

I am creating an app in which the user can search for a book using an api call. I am getting this error whenever I search for a book. The reason is because the authors array is initially undefined. But this doesn't happen with the title or the thumbnail. Any way to fix this error?

I am new to React and I have this search component which updates the search result based on the value of the input from the user:

I am new to react and am having a hard time debugging it.

I have the below code: App.js

I am working on an Android app that displays a list of books that match a search term. I am using the Google Books API. From the API I get a list of the following items: title, author, publication date and URI for a small thumbnail to display.

I am able to display the information in the RecyclerView except the thumbnail. For that I am trying to use the Glide library. It always stays blank and if I use the placeholder option it always displays the placeholder. (I have added the dependencies in the Gradle file also).
