海外TECH	DEV Community	Moving From Electron to Tauri	https://dev.to/pgenfer/moving-from-electron-to-tauri-3791	Moving From Electron to TauriPart Interprocess Communication ーporting a Typescript based message system of an Electron App to Tauri and Rust TL DR Tauri is a Rust based Electron alternative However porting an existing Electron application to Tauri requires some work This post explains how UMLBoard s message system used for inter process communication could be ported to Rust without much effort Many people would agree that native apps if done right provide better user experience and performance compared to hybrid or cross platform solutions However having separate apps also means maintaining different code bases each written in its own language Keeping them all in sync is quite a lot of work for a single developer usually more than what we ve planned for our side projects The Electron framework is a compromise It provides a convenient way to write platform independent applications using a web based technology stack most people are familiar with Also the framework is very mature and actively supported by a large community But nevertheless it s only a compromise Its platform independence comes with the cost of larger binaries and higher memory consumption compared to native apps Take for instance UMLBoard s macOS binaries The universal platform package ends up with a total size of MB that s a massive number for a lightweight drawing tool Still alternatives with the same level of maturity as Electron are relatively rare Tauri however is one of these alternatives that looks very promising A First look at TauriWhile Electron and Tauri share some similarities like using separate processes for their core and rendering logic they follow divergent philosophies regarding bundle size Instead of deplyoing your application with a complete browser frontend Tauri relies on the built in Webviews the underlying operating systems provide resulting in much smaller applications Despite that Tauri uses Rust as the language of choice for its Core process resulting in better performance compared to Electron s node js backend While porting UMLBoard from Electron to Rust won t happen overnight exploring how some of its core concepts could be translated from TypeScript to Rust would still be interesting The following list contains some crucial features of UMLBoard Some of them are real show stoppers in case they don t work A possible port would have to deal with these issues first x Porting the inter process communication to Tauri this post here Accessing a document based local data store with Rust Validate the SVG compatibility of different Webview Check if Rust has a library for automatic graph layoutingThe remaining post is dedicated to the first bullet point We will investigate how UMLBoard s existing inter process communication could be ported to Tauri The other topics may be the subjects of further articles Ok but enough said let s start Sending Messages between Electron ProcessesUMLBoard s current implementation uses a React front end with Redux state management Every user interaction dispatches an action that a reducer translates into a change resulting in a new front end state If for instance a user starts editing a classifier s name a renamingClassifier action gets dispatched The classifier reducer reacts to this action and updates the classifier s name triggering a rerender of the component So far this is all standard Redux behavior A user input dispatches a redux action that leads to a state update in the front end But UMLBoard even goes one step further and uses the same technique for sending notifications to Electron s main process Taking our previous example when the user hits the ENTER key a renameClassifier action is dispatched indicating that the user finished editing This time however the action gets processed by a custom middleware instead of a reducer The middleware opens an IPC channel and sends the action directly to the main process There a previously registered handler reacts to the incoming action and processes it It updates the domain model accordingly and persists the new state to the local datastore If all that goes well a response action is sent back on the same channel The middleware receives the response and dispatches it like a regular action This keeps the front end state in sync again with the domain state See the following diagram for an overview of this process Inter Process Communication between renderer and main process in UMLBoard It might look a bit odd to extend Redux to the main process but from the view of a lazy developer like me it has some benefits Since both mechanisms Redux and IPC rely on plain serializable JSON objects everything that goes through a Redux dispatcher can also go through an IPC channel This is very convenient as it means we can reuse our actions and their payloads without writing additional data conversions or DTO objects We also don t have to write any custom dispatching logic We only need a simple middleware to connect the Redux front end with the IPC channel This action based messaging system is the backbone of UMLBoard s process communication so let s see how we can achieve this in Tauri Porting to TauriFor our proof of concept we will create a small demo application in Tauri The app will use a React Redux front end with a single text field Pressing a button will send the changes to the backend Tauri s Core process The example app we re going to implement We are only interested in inter process communication so we will skip all state tracking in the core process this will be part of a future blog entry That s why our Cancel method behaves a bit weird as it will always restore the original class name But for proving our concept this should be sufficient We basically have to implement four tasks Declare Rust equivalents of our Redux actionsSending actions from Webview to Core processHandling incoming actions in the Core processSending response actions back to WebviewLet s go through the implementation step by step Declare Rust equivalents of Redux actionsRedux actions are plain JSON objects with a string identifying their type and a field holding their payload Rust has a similar concept we could use to mimic this behavior the Enum type Enums in Rust are more powerful than in other languages because they allow storing additional data for each variant In that way we could define our Redux actions as a single Enum where each variant represents an individual type of action derive Serialize Deserialize Display serde rename all serialize camelCase deserialize camelCase serde tag type content payload enum ClassiferAction received from webview when user changed name RenameClassifier EditNameDto user canceled name change operation CancelClassifierRename response action after successful change ClassifierRenamed EditNameDto response action for cancel operation ClassifierRenameCanceled EditNameDto error response ClassifierRenameError To convert our Redux action into a Rust Enum and vice versa we can use Rust s serde macro We specify that the variant s name should be serialized into a type field and its data into a field called payload This corresponds precisely to the scheme we use to define our Redux actions But we can even go one step further by using the ts rs crate This library can generate the TypeScript interfaces for the action payloads straight from our Rust code We don t have to write a single line of TypeScript code for this That s really neat Decorating our Rust struct with the relevant macros derive TS ts export rename all camelCase struct EditNameDto new name String gives us the following auto generated TypeScript interface for our action payloads This file was generated by ts rs Do not edit this file manually export interface EditNameDto newName string Ok we have the correct data types on both edges of our communication channel let s now see how we can send data between them Sending actions from Webview to Core processInterprocess communication in Tauri is done through commands These commands are implemented as Rust functions and can be called within the Webviews using the invoke API One problem we face is that the Redux Toolkit generates the type for identifying an action by concatenating the name of the slice where the action is defined with the action s name In our case the resulting type would therefore be classifier renameClassifier instead of just renameClassifier This first part classifier is also called the domain to which this action belongs Unfortunately this naming convention does not work for Rust as it would result in invalid names for our Enum options We can avoid this by separating the domain from the action type and wrapping everything up in an additional object the IpcMessage before submitting See the following diagram for the complete invocation process Invoking a Tauri command from the Webview process Handling incoming actions in the Core processOn the backend side we must also define a Rust struct for our IpcMessage Since we don t know the concrete type of the payload yet we keep it stored as a JSON value and parse it later when needed data structure to store incoming messages derive Deserialize Serialize struct IpcMessage domain String action Value We can now define the signature of the method for our Tauri command Our function ipc message will receive an IpcMessage processes it somehow and at the end returns another IpcMessage as a response tauri command fn ipc message message IpcMessage gt IpcMessage TODO implement Ok but what would the actual implementation look like The function should take the domain from the message see if a handler is registered for this domain and if yes call the corresponding handler with the action stored inside our IpcMessage Since we will have many different domains and handlers later it makes sense to minimize the implementation effort by extracting common behavior into a separate ActionHandler trait trait that must be implemented by every domain servicepub trait ActionHandler specifies the domain actions this trait can handle type TAction DeserializeOwned Serialize std fmt Display the domain for which this handler is responsible fn domain amp self gt amp str must be implemented by derived structs fn handle action amp self action Self TAction gt Result lt Self TAction serde json Error gt boiler plate code for converting actions to and from json fn receive action amp self json action Value gt Result lt Value serde json Error gt convert json to action let incoming Self TAction serde json from value json action call action specific handler let response self handle action incoming convert response to json let response json serde json to value response Ok response json The trait uses the TemplateMethod design pattern The receive action specifies the general workflow for converting the action The handle action method contains the actual logic for processing a specific action In our case a ClassifierService could be responsible for processing all actions of the domain classifier ClassifierService handles all classifier specific actionsstruct ClassifierService impl ClassifierService pub fn update classifier name amp self new name amp str gt TODO implement domain logic here impl ActionHandler for ClassifierService type TActionType ClassifierAction fn domain amp self gt amp str CLASSIFIER DOMAIN fn handle action amp self action Self TActionType gt Result lt Self

EditNameDto new name Old Classname to string if front end sends different actions something went wrong gt ClassifierAction ClassifierRenameError Ok response Sending response actions back to WebviewWe re almost done We have the signature of our Tauri command and the code we need to handle an action and generate a response If we glue everything together our final ipc message function may look like the following snippet tauri command fn ipc message message IpcMessage gt IpcMessage This code is just for demonstration purposes In a real scenario this would be done during application startup let service ClassifierService let mut handlers HashMap new handlers insert service domain amp service this is were our actual command begins let message handler handlers get amp message domain unwrap let response message handler receive action message action unwrap IpcMessage domain message handler domain toString action response Please note that the service creation and registration code are only for demonstration purposes In an actual application we would instead use a managed state to store our action handlers during application startup We also omitted the error handling here to keep the code simple However there are quite some scenarios we should check e g what should happen if no handler is found or how should we proceed if parsing an action into an enum goes wrong etc ConclusionOur proof of concept was successful Sure some parts of the implementation can be tweaked but porting UMLBoard s IPC messaging from Electron TypeScript to Tauri Rust is definitely manageable Rust s enums are an elegant and type safe way to implement our message system We only have to ensure that potential serialization errors are handled when converting JSON objects into our enum variants In the next post in this series we will try to use a document based local database to store our domain model Hopefully by then I ll finally understand how the borrow checker works What s your opinion on that Have you already worked with Tauri and Rust and what were your experiences Please share your thoughts in the comments or via Twitter umlboard Title Image from Wallpaper Flare Source code for this project

海外TECH	DEV Community	[Safe-TypeORM] AnyORM becomes the real TypeORM	https://dev.to/samchon/safe-typeorm-make-anyorm-to-be-the-real-typeorm-478n	Safe TypeORM AnyORM becomes the real TypeORM SummaryMake anyorm to be real typeorm safe typeorm is a helper library of typeorm enhancing type safety like below When writing SQL query Errors would be detected in the compilation levelAuto Completion would be providedType Hint would be supportedYou can implement App join very convenientlyWhen SELECTing for JSON conversionApp Join with the related entities would be automatically doneExact JSON type would be automatically deducedThe performance would be automatically tuned AnyORMThe most famous ORM library in TypeScript is typeorm However Korean TypeScript backend developers jokingly call the TypeORM as AnyORM It s because the typeorm does not guarantee type safety so that cause lots of critical runtime errors As you can see from below code JOIN or SELECT queries are written as a string typed value and it never be validated in the compilation level TypeScript developers can identify error only when running the backend server code Such type unsafety is the reason why I ve developed safe typeorm a wrapper library typeorm to make it from AnyORM to be real typeorm class User PrimaryGeneratedColumn id number Column name string OneToMany gt Photo photo gt photo user photos Photo const users await

another ORM library prisma has been newly inveted and it was much elegant than typeorm As the prisma ensures perfect type safety and much convenient to use than typeorm I also moved from typeorm to prisma Therefore no reason to maintain the safe typeorm due to I m not using typeorm more RevivalHowever unlike my case abandoned typeorm and adapted prisma many companies have been suffering by AnyORM typeorm and its type unsafety One of such company traveled my Github Account and unearthed the safe typeorm The company requested me like below We have been suffering from type unsafety of TypeORM We had wrapped the TypeORM to our self developed module for enhancing type safety but it had been too hard works for us In nowadays we ve found your safe typeorm library and it seems like the solution what we ve looked for Can you write a Guide Documents I was a little bit surprised and could hear lots of voices from another companies using NestJS in South Korea What they had in common was that they are suffering from AnyORM but it was too risky to migrate their currently running commercial backend server to prisma Most of them are dreaming to prisma but it is not possible by legacy code Thus I urgently wrote a Guide Documents It took years after the completion of safe typeorm library that the Guide Documents was created It is a pleasure story for me that there re some people who want my old libraries but I also feel regretful that I left it for two years because I couldn t think of such specific requirements Contents of Guide Documents written in two days
