Issue: Bootstrap The Near React Library

by ADMIN 40 views

As a developer, setting up a well-structured project is crucial for building and extending Near React efficiently. In this article, we will guide you through the process of bootstrapping the Near React library, covering the necessary steps to create a solid foundation for your project.

Acceptance Criteria

To ensure that our project is properly set up, we need to meet the following acceptance criteria:

Initialize the project with npm and package.json

The first step in setting up our project is to initialize it with npm and create a package.json file. This file will contain metadata about our project, including its name, version, and dependencies.

npm init -y

This command will create a package.json file with default values. We can then modify this file to suit our project's needs.

Set up TypeScript with strict type checking

TypeScript is a superset of JavaScript that adds optional static typing and other features. To set up TypeScript with strict type checking, we need to install the typescript package and configure it in our tsconfig.json file.

npm install --save-dev typescript

Next, we need to create a tsconfig.json file in the root of our project. This file will contain configuration options for the TypeScript compiler.

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "outDir": "build"
  }
}

This configuration tells the TypeScript compiler to target ES6 syntax, use the CommonJS module system, and enable strict type checking.

Create the project folder structure

Next, we need to create the project folder structure. This will help us keep our code organized and make it easier to navigate.

mkdir src/hooks
mkdir src/providers
mkdir src/components
mkdir src/utils
mkdir src/types
mkdir examples

This will create the following folders:

  • src/hooks: for custom hooks
  • src/providers: for global state management
  • src/components: for reusable UI components
  • src/utils: for utility functions
  • src/types: for custom types
  • examples: for example code

Set up Rollup for bundling

Rollup is a popular bundler for JavaScript applications. To set up Rollup, we need to install the rollup package and create a rollup.config.js file.

npm install --save-dev rollup

Next, we need to create a rollup.config.js file in the root of our project. This file will contain configuration options for Rollup.

import { terser } from 'rollup-plugin-terser';
import { eslint } from 'rollup-plugin-eslint';

export default {
  input: 'src/index.ts',
  output: {
    file: 'build/index.js',
    format: 'cjs'
  },
  plugins: [
    eslint(),
    terser()
  ]
};

This configuration tells Rollup to bundle our code from the src/index.ts file and output it to the build/index.js file.

Add Git ignore rules

To prevent our .gitignore file from being committed to the repository, we need to add the following rules:

echo "node_modules/" >> .gitignore
echo "build/" >> .gitignore
echo "src/types/*.d.ts" >> .gitignore

This will prevent the node_modules and build folders from being committed to the repository.

Create a basic useWallet hook as a starting point

The useWallet hook is a basic hook that will be used as a starting point for our wallet connection logic.

import { useState, useEffect } from 'react';

const useWallet = () => {
  const [wallet, setWallet] = useState(null);

  useEffect(() => {
    // wallet connection logic will go here
  }, []);

  return wallet;
};

export default useWallet;

This hook will be used to connect to the wallet and retrieve the wallet's state.

Create a WalletProvider for global wallet state management

The WalletProvider is a component that will be used to manage the global wallet state.

import React, { useState, useEffect } from 'react';
import useWallet from './useWallet';

const WalletProvider = ({ children }) => {
  const wallet = useWallet();

  return (
    <WalletContext.Provider value={wallet}>
      {children}
    </WalletContext.Provider>
  );
};

export default WalletProvider;

This component will wrap our application and provide the wallet's state to all components.

Ensure npm run build compiles successfully

To ensure that our code compiles successfully, we need to run the following command:

npm run build

This command will compile our code and output it to the build folder.

Tech Stack

The following technologies will be used in this project:

  • React: a popular JavaScript library for building user interfaces
  • TypeScript: a superset of JavaScript that adds optional static typing and other features
  • near-api-js: a JavaScript library for interacting with the Near blockchain
  • Rollup: a popular bundler for JavaScript applications
