Visualize the architecture of your Ruby app in RubyMine in ¹ ₂minutesAppMap is an open source RubyMine plugin which helps you improve your code by showing you how it behaves feature by feature as you work It does this by automatically generating interactive maps of architecture and code behavior right in your editor This ¹ ₂minute video shows how to install the AppMap plugin how to configure it to map your Ruby application and how to navigate your code using the interactive diagrams It uses the Rails Sample App as an example program Here are the step by step instructions that are demonstrated in the video or you can follow the Quickstart AppMap instructions directly in your RubyMine IDE How it worksAppMap works by recording code execution paths of your app and visualizing them in interactive diagrams directly in your code editor A good way to create AppMaps is by recording unit functional or integration test cases The Rail Sample App project uses minitest tests which will be a source of AppMaps in this demo Install the AppMap plugin Installing AppMap from the JetBrains Marketplace takes only a moment Open the RubyMine preferencesSelect Plugins click on the Marketplace tab and search for AppMapClick on the Install button then click on Restart IDE When the IDE restarts the AppMap plugin is installed and ready for viewing AppMaps Configure AppMap for the Rails Sample App recording Add appmap gem appmap railtie and appmap for minitest In the first step instrument the application for AppMap recording Add the appmap gem to the Gemfile and run bundle to install group development test do gem appmap Next add the appmap railtie The railtie will only be activated if the appmap gem is in the bundle require appmap railtie if w test development member Rails env The Rails Sample App uses minitest To test helper rb addrequire appmap minitest This should be placed before any of the application code is loaded Configure appmap ymlThe AppMap framework uses a file called appmap yml to determine which code to map Create a new file appmap yml in the root folder of your project You should add all the source folders and gems of your project that you want to capture Here is an example for the Rails Sample App that is used in this demo name sample app th edpackages path app controllers path app helpers path app jobs path app mailers path app models gem image processing gem mini magick gem active storage validations gem bcrypt gem will paginate Record AppMaps from tests Now you are ready to record an appmap To get a recording run a test with the environment variable APPMAP trueIt is easy to modify the test Run configuration to include the APPMAP variable in RubyMine When the test is run an AppMap will be recorded in the tmp appmap minitest folder Note you can run the tests and record AppMaps directly from the command line APPMAP true bundle exec rake test Open a generated AppMap in RubyMine Open the AppMaps view click on the AppMaps tab in the UI Or press CTRL or COMMAND SHIFT A then type AppMaps in the search box and pick the AppMaps View from the list Select an AppMap from the list of all AppMaps found in the project folders or search for an AppMap with a specific phrase in its name Double click on an AppMap in the list an interactive diagram viewer opens Interact with the AppMap diagram Discover how the Rails Sample Application works in the AppMap diagrams Start with the big picture of your software design and view all code components in the Dependency Map Web Service endpoints Java packages classes functions and SQL commands and their inter dependenciesNavigate to sources of classes and functions directly from the diagrams so you don t have to look for them manuallyDrill down the execution details of code and SQL in the execution Trace Or you can use a bottom up approach Let s say you want to know what code modifies data in the database Start with a SQL command of interest like an UPDATEView how it s connected to other calls in the Trace then backtrack to its calling component and open its source file See how it is connected to other code and Web Service endpoints Learn more about AppMapThis is only a small demonstration of the AppMap capabilities For more information step by step instructions and practical how tos check out the AppMap documentation AcknowledgementsThanks to Petr and Dan for all their hard work on this video |

Error Handling In React. |
https://dev.to/barnabas19/error-handling-in-react-3h0a
|
Error Handling In React IntroductionIn this article we are going to cover the basics of error handling in React At the end of this article you should know what an error boundary is and how to build one know the two methods involved in error handling phase of a React component componentDidCatch error info and static getDerivedStateFromError error become a better React developer Let s dive in Error Boundaries The What Error boundaries are class components designed to catch run time errors anywhere in the React component tree and display a fallback view user interface in the event of such errors It usually implements either one or both of the lifecycle methods componentDidCatch or getDerivedStateFromError Error Boundaries The Why When an error occurs at run time React basically unmounts the entire component tree leaving our application broken with an error message popping up Take for instance an e commerce application We definitely do not want our customers to have something like that pop up on their devices whenever an error occurs in the application Instead we want to prepare beforehand a fallback view and render that view in case an error occurs in production We can achieve this with error boundaries componentDidCatch and getDerivedStateFromErrorThese are two lifecycle methods implemented in an error boundary Recall that an error boundary is simply a React class component getDerivedStateFromError is used to render a fallback view whenever an error occurs componentDidCatch is used to log the error information Let s Build An Error BoundaryFirst we create a component called Demo in Demo js file and mount the component in our App js file All Demo does is render a simple view Demo js import React from react import Demo css const Demo props gt if props theme white throw new Error An error occurred return lt section gt lt h gt This is a props theme text lt h gt lt section gt export default Demo App js import React from react import Demo from Demo const App gt return lt div className App gt lt Demo theme black gt lt div gt export default AppOutput Now let s mount two more instances of Demo in App We now have a total number of three Demo components in App One out of the three components throws an error import React from react import Demo from Demo const App gt return lt div className App gt lt Demo theme black gt lt Demo theme black gt lt Demo theme white gt lt div gt export default AppThis crashes the entire application We do not want our entire application to crash just because of one or few component s that has have an error Instead we wrap that component with an error boundary By wrapping such component with an error boundary only that component is affected and handled The remaining components still remain unaffected As the name implies error boundary we are setting boundaries around errorsLet s now go ahead and build our error boundary Go back to your text editor and create a new file Name it whatever you like But I ll call mine ErrorBoundary js for semantics In ErrorBoundary js I will create a class component called ErrorBoundary import React Component from react class ErrorBoundary extends Component constructor props super props this state throwsError false static getDerivedStateFromError error return throwsError true componentDidCatch error info console log error console log info render if this state throwsError return lt h gt Oops An error occurred lt h gt return this props children export default ErrorBoundaryAfterwards I will import my ErrorBoundary component in App and wrap all three Demo components with ErrorBoundary import React from react import Demo from Demo import ErrorBoundary from ErrorBoundary const App gt return lt div className App gt lt ErrorBoundary gt lt Demo theme black gt lt Demo theme black gt lt Demo theme white gt lt ErrorBoundary gt lt div gt export default App Output Note In the development environment we still see the error This is because React still wants you to know the source of your errors and make sure you fix them while building your application Error boundaries are only useful in production environments So it s an intended behaviour However you can click on the close button at the top right so that you can see your fallback view in action We can see how our fallback view is gracefully rendered You can be as creative as you like with your fallback user interface Let us walk through the ErrorBoundary component source code Within the class we define a constructor which initializes the class with some state In this state object we set a state property throwsError to false initially Next we define a method static getDerivedStateFromError error This method receives a parameter error Within the function body we returned a new state object which has a property called throwsError set to true This new state object will be used to change this state throwsError initially set to false in the constructor to true whenever a component throws an error A change in state this state throwsError will trigger a rerender lifecycle causing our fallback view to be displayed In the render method we create our desired fallback view the h tag which will display when this state throwsError is true Or else display the actual child components this props children when there is no error In componentDidCatch method we simply log the error and the error information to the console Where Should You Place Your Error Boundaries What we initially did was enclose all the Demo components with our error boundary So if there is an error in any component within the error boundary everything within the error boundary including healthy components will be hidden and the fallback view rendered Not ideal We should isolate each Demo component with an error boundary so only the faulty component gets hidden by the fallback view Let us edit our App js file by wrapping each Demo component with our error boundary import React from react import Demo from Demo import ErrorBoundary from ErrorBoundary const App gt return lt div className App gt lt ErrorBoundary gt lt Demo theme black gt lt ErrorBoundary gt lt ErrorBoundary gt lt Demo theme black gt lt ErrorBoundary gt lt ErrorBoundary gt lt Demo theme white gt lt ErrorBoundary gt lt div gt export default App Now we can see that only the third Demo component which has an error gets hidden by the fallback view The placement of your error boundary is totally up to you But it is reasonable to isolate your components so that other components do not get affected when one or few component s throw s an error Conclusion In the last few minutes we have learned what an error boundary is and the lifecycle methods it implements We have also seen how to create and use it in our react applications Hopefully you now have the basic skills to handle errors in your React projects |
