Chapter 9 : React and TypeScript : The Production Grade Code

First Complete your TS playlist in Manual

TypeScript (TS) and its application with React requires a structured approach

1. Introduction to TypeScript:​

1. Introduction to TypeScript:​

a. What is TypeScript?

  • Content: Overview of TypeScript, its motivations, and its advantages over vanilla JS.
  • Task: Install TypeScript and set up a basic TypeScript project using tsc.

b. Basic Types in TypeScript:

  • Content: Introduction to basic data types in TS such as string, number, boolean, null, and undefined.
  • Task: Create simple variables of each type and try type-assertions and type-inferences.

c. Interfaces and Custom Types:

  • Content: Dive into defining shapes for objects using interfaces and type keyword.
  • Task: Create an interface for a user profile and a product in an online store.

2. Advanced TypeScript Concepts:​

a. Union, Literal, and Intersection Types:

  • Content: Overview of combining types and defining specific set values.
  • Task: Define a type that could be a string or a number, and a type for specific string values (e.g., "small" | "medium" | "large").

b. Generics:

  • Content: Understand the power of reusability and dynamic types using generics.
  • Task: Create a generic function to return an array of any type.

c. Modules and Namespaces:

  • Content: Learn to organize and modularize the code using TS.
  • Task: Split the user profile and product interfaces into separate modules and import/export them.

d. Decorators:

  • Content: Dive into advanced TypeScript feature for class modification or decoration.
  • Task: Create a simple decorator to log class instantiations.

3. Setting up TypeScript with Tooling:​

a. TSConfig:

  • Content: Understand the configuration options provided by TypeScript's tsconfig.json.
  • Task: Set up a project with specific compiler options like "strict" and "esModuleInterop".

b. Linting and Formatting:

  • Content: Introduce tools like TSLint or ESLint (with TS plugins) and Prettier.
  • Task: Set up linting and formatting for a TypeScript project and fix any linting issues.

4. TypeScript with React:​

a. Setting up a TS-React Project:

  • Content: Introduction to create-react-app with TypeScript template.
  • Task: Bootstrap a new React project with TypeScript.

b. React Components in TypeScript:

  • Content: Understand how to define functional and class components in TS.
  • Task: Create a basic functional component with props using TypeScript.

c. State and Props with TypeScript:

  • Content: Dive deeper into how to type-check component props, state, and events.
  • Task: Develop a small app (e.g., a to-do app) where they define types for state and props.

d. Using third-party libraries with TypeScript:

  • Content: Introduction to DefinitelyTyped and using third-party libraries in a TS project.
  • Task: Install a library like lodash and use it in the project, ensuring it's type-safe.

5. Real-world Application Development:​

a. Routing with TypeScript:

  • Content: Introduction to react-router with TypeScript.
  • Task: Extend the to-do app with routing, creating separate pages for viewing tasks and adding tasks.

b. State Management with TypeScript:

  • Content: Use state management libraries like Redux or Zustand with TypeScript.
  • Task: Refactor the to-do app to use Redux for state management, ensuring actions and reducers are type-safe.

c. API Calls and Data Fetching:

  • Content: Type-checking responses from APIs and handling them in React.
  • Task: Fetch a list of todos from a public API, type-check the response, and display it.
