Description

A warm welcome to the TypeScript: Build Scalable and Robust Applications course by Uplatz.TypeScript is a superset of JavaScript that adds static typing to the language. This means that you can define the types of variables, functions, and other entities in your code, which allows the TypeScript compiler to catch type errors before your code is even run.TypeScript acts as a powerful tool that helps you write safer, more maintainable code by catching type errors before they reach runtime. The end result is still JavaScript code that can be executed anywhere JavaScript is supported.How TypeScript WorksTypeScript works by adding a layer of static typing on top of JavaScript. The process works as follows:1. Writing TypeScript CodeYou write your code using TypeScript syntax, which includes type annotations. These annotations specify the expected data types for variables, functions, and other elements in your code.2. Compilation (Transpilation)The TypeScript compiler (tsc) takes your TypeScript code and converts it into standard JavaScript code. This process is called transpilation because it transforms the code from one version of JavaScript (with types) to another (without types).During compilation, the TypeScript compiler performs type checking. It analyzes your code to ensure that the types are used consistently and that there are no type errors. If it finds errors, it will report them, preventing you from generating the JavaScript output until you fix them.3. Running the JavaScript CodeThe JavaScript code generated by the compiler can be run in any JavaScript environment, such as a web browser or Node.js. Since the types are removed during compilation, the JavaScript runtime doesn't need to understand TypeScript's type system.Key ConceptsStatic Typing: TypeScript's core feature. It allows you to define the types of variables, functions, and other entities. This helps catch type errors early in development.Type Annotations: You explicitly specify the types of your variables and functions using a specific syntax (e.g., let name: string = "Alice";).Type Inference: TypeScript can often infer types automatically, even if you don't explicitly write them. This reduces the amount of code you need to write.Compiler: The tsc compiler is responsible for converting TypeScript code to JavaScript and performing type checking.Transpilation: The process of converting TypeScript code to JavaScript.TypeScript brings a lot to the table, making it a popular choice for modern web development. Some of its key features are:Static Typing: This is the heart of TypeScript. It lets you define the types of variables, functions, and other elements in your code. This helps catch type errors during development, before they cause problems at runtime.Type Inference: TypeScript is smart enough to often figure out types even if you don't explicitly write them. This makes your code less verbose while still providing the benefits of typing.Interfaces: These define the "shape" of objects, specifying what properties and methods they should have. They help ensure that different parts of your code work together smoothly.Classes: TypeScript supports object-oriented programming with classes, allowing you to create reusable blueprints for objects with properties and methods.Generics: These allow you to write code that can work with a variety of types without sacrificing type safety. This is especially useful for creating reusable components and functions.Enums: Enums provide a way to define a set of named constants, making your code more readable and maintainable.Decorators: These are a way to add extra functionality to classes, properties, methods, and accessors. They can be used for things like logging, dependency injection, and more.Modules and Namespaces: These help you organize your code into logical units, making it easier to manage and maintain large projects.Tooling: TypeScript has excellent tooling support, including features like code completion, refactoring, and debugging in your IDE.Compatibility: TypeScript compiles down to regular JavaScript, so it works seamlessly with existing JavaScript libraries and frameworks.TypeScript - Course CurriculumModule 1: Introduction to TypeScriptIntroduction to TypeScriptWhat is TypeScript?Why should we learn TypeScript?TypeScript vs JavaScriptSetting Up TypeScript EnvironmentInstalling TypeScriptWriting your first TypeScript programUnderstanding the TypeScript project structureConfiguring tsconfig.jsonModule 2: TypeScript BasicsBasic TypeScript SyntaxPrimitive types (string, number, boolean, etc.)Explicit vs inferred typesComplex TypesArrays, Tuples, and EnumsUnion and Intersection types (with examples)Advanced TypeScript TypesInterfaces and Type AliasesDefault values, unions, and intersectionsType Assertions, Function Types, and GenericsType assertionsFunction typesIntroduction to GenericsModule 3: Object-Oriented TypeScriptWorking with Classes and ObjectsCreating classes and objectsAccess modifiers (public, private, protected)Readonly propertiesAdvanced Class FeaturesGetters and settersStatic properties and methodsAbstract classes and inheritanceObject-Oriented Programming in TypeScriptImplementing OOP principlesHands-on projectModule 4: TypeScript Modules and IntegrationUnderstanding TypeScript ModulesOrganizing and using modulesImporting and exportingIntegrating TypeScript with JavaScript FrameworksUsing TypeScript with React and Node.jsDeclaration Files and Frontend ToolingUsing declaration files (.d.ts)Working with frontend tools like Webpack and BabelModule 5: TypeScript Utilities and FeaturesUseful TypeScript UtilitiesUtility types (Partial, Readonly, Record, etc.)Best practicesFunction Types and OverloadingFunction signaturesOverloading functionsDeep Dive into TypeScript Classes and InheritanceExtending classesUsing mixinsExploring Access Modifiers and Readonly PropertiesReal-world examplesModule 6: Hands-on TypeScript ProjectsBuilding a Modular ApplicationStructuring a scalable TypeScript appBuilding a Type-Safe LibraryCreating a library with strict typingTypeScript with AngularSetting up an Angular project with TypeScriptUsing TypeScript with Vue.jsDeveloping a Vue.js project with TypeScriptModule 7: Error Handling, Debugging, and CompilationError Handling in TypeScriptCatching and managing errorsDebugging TypeScript codeUnderstanding TypeScript Compiler OptionsExploring tsc optionsModule 8: Advanced TypeScript ConceptsWorking with TypeScript MixinsCreating reusable mixinsBuilding a Notification System using MixinsHands-on projectExploring TypeScript DecoratorsClass, method, and property decoratorsAdvanced Generics in TypeScriptConditional types and mapped typesModule 9: Full-Stack TypeScript DevelopmentBuilding a REST API with TypeScriptSetting up an Express.js backend with TypeScriptCreating Endpoints and Handling RequestsCRUD operationsSetting Up a TypeScript Frontend ProjectConfiguring a frontend appState Management with TypeScriptUsing Vanilla TypeScript, Context API, and ReduxTypeScript RoutingHandling navigation with React RouterAPI Integration with TypeScriptUsing Axios with TypeScriptUnit Testing in TypeScriptTesting with JestPreparing for Production and DeploymentBest practices for production-ready TypeScript appsModule 10: TypeScript for Mobile DevelopmentWhy Use TypeScript with React Native?Benefits of TypeScript in mobile appsCreating a React Native Project with TypeScriptStep-by-step guide using ExpoModule 11: TypeScript Namespaces and Utility ProjectsUnderstanding TypeScript NamespacesOrganizing code with namespacesQuote Generation Project with TypeScriptStep-by-step projectBlog Post Manager ProjectCRUD operations in TypeScriptBlog Post Manager with SQLiteDatabase integrationBuilding a Password Generator in TypeScriptNode.js and React implementationsModule 12: Interview Preparation & ConclusionCommon TypeScript Interview QuestionsExplanation with examples and tablesLearning TypeScript can definitely open up some exciting career opportunities.
