Electron, TypeScript & React - The Holy Trinity

During the past weeks I’ve been working on a project that involves getting Electron, TypeScript & React working together. When I started the project I did what every Sr. Software Engineer would do, I went to Google and typed “How to setup TypeScript, React & Electron”. I was expecting find a solution on the first results but I didn’t find what I was looking for. After some research, many tabs on my browser and several attempts I was able to setup correctly my development environment.

I decided to create this blog post to share with you what I called The Holy Trinity.

Project Setup

First of all you need to start your project by running

yarn init

npm init

After answering the questions that were prompted, it's time to install the dependencies that you need.

Project structure

This is the folder structure that I used, not sure if it is the best but it worked for me

webpack.config.js
tsconfig.json
package.json
src/
  assets/
  electron.ts
  index.tsx
  index.html

Electron

Installing Electron is the easiest task, all what you need is to install the dependency and add it to your package.json

yarn add electron -D

You can corroborate that Electron was installed correctly by creating a Hello World, just create a new file index.js

const { app } = require('electron')

app.on('ready', () => {
  console.log('Hello world');
});

And then just run

electron index.js

TypeScript

In order to setup TypeScript all what you need is just to install the dependencies

yarn add typescript -D

After that you need to write your tsconfig.json. This worked like a charm for me

{
  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es6", "dom"],
    "module": "es6",
    "moduleResolution": "node",
    "sourceMap": false,
    "target": "es5",
    "jsx": "react",
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "baseUrl": ".",
    "paths": {
      "@app/*": ["src/*"],
    }
  },
  "exclude": [
    "**/*.spec.ts",
    "node_modules",
    "vendor",
    "public"
  ],
  "compileOnSave": false
}

This may change depending on your folder structure, I like to put all my code inside a src/ directory and I also wanted to avoid the relative path hell

import Component from '.../.../../../component';

So I just declared an absolute path

....
  "paths": {
      "@app/*": ["src/*"],
    }
...

React

yarn add react react-dom

Given that you already installed TypeScript, you might want to install @types/react as well

yarn add @types/react @types/react-dom -D

You may noticed that you didn’t used the -D when you added react and react-dom, this is due to all your JSX is converted to a syntax similar to React.createElement and hence you would require your app to have React during run time as well.

Webpack

You just installed The Holy Trinity dependencies but you still need to compile your TypeScript/React code and generate a bundle file that Electron can read, that's a task for Webpack.

You just need to install a “few” dependencies, you probably won’t need some of them.

yarn add webpack webpack-cli copy-webpack-plugin css-loader file-loader postcss-loader sass-loader style-loader ts-loader url-loader html-webpack-plugin precss autoprefixer -D

Then you must configure Webpack, this is the webpack.config.js that worked for me but it might change depending on your project folder structure.

const webpack = require('webpack');
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');

const mode = process.env.NODE_ENV || 'development';

module.exports = [
  {
    mode,
    entry: {
      electron: path.resolve('./src/electron.ts'),
    },
    target: 'electron-main',
    node: false,
    module: {
      rules: [
        {
          test: /\.ts$/,
          include: /src/,
          use: [{ loader: 'ts-loader' }]
        }
      ]
    },
    output: {
      path: path.resolve(__dirname, 'build'),
      filename: '[name].js'
    },
    resolve: {
      extensions: [ '.tsx', '.ts', '.js' ],
      alias: {
        '@app': path.resolve(__dirname, 'src/')
      }
    }
  },
  {
    mode,
    node: false,
    entry: {
      index: path.resolve('./src/index.tsx'),
    },
    target: 'electron-renderer',
    module: {
      rules: [
        {
          test: /\.ts(x?)$/,
          include: /src/,
          use: [{ loader: 'ts-loader' }]
        },
        {
          test: /\.css$/,
          use: ['style-loader', 'css-loader']
        },
        {
          test: /\.(scss)$/,
          use: [{
            loader: 'style-loader',
          }, {
            loader: 'css-loader',
          }, {
            loader: 'postcss-loader',
            options: {
              plugins: function () {
                return [
                  require('precss'),
                  require('autoprefixer')
                ];
              }
            }
          }, {
            loader: 'sass-loader'
          }]
        },
        {
          test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
          issuer: {
            test: /\.jsx?$/
          },
          use: ['babel-loader', '@svgr/webpack', 'url-loader']
        },
        {
          test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
          loader: 'url-loader'
        },
        {
          test: /\.(jpe?g|png|gif)$/i,
          loader: 'url-loader'
        }
      ]
    },
    resolve: {
      extensions: [ '.tsx', '.ts', '.js' ],
      alias: {
        '@app': path.resolve(__dirname, 'src/')
      }
    },
    output: {
      path: path.resolve(__dirname, 'build'),
      filename: '[name].js'
    },
    plugins: [
      new HtmlWebpackPlugin({
        template: './src/index.html'
      }),
      new CopyWebpackPlugin([
        { from:'src/assets',to:'assets' }
      ])
    ]
  },
]

If you are familiarized with Electron, you might know that it has a main and render process, so I decided that the best would be writing a configuration for each process.

We need to specify an entry point and a target for each process.

Main process

entry: {
      electron: path.resolve('./src/electron.ts'),
    },
    target: 'electron-main',

Render process

entry: {
      index: path.resolve('./src/index.tsx'),
    },
    target: 'electron-renderer',

That's it!!! You should be able to compile your TypeScript code and execute your Electron application by just running:

./node_modules/webpack/bin/webpack.js --config ./webpack.config.js
electron ./build/electron.js

The best would be write this as scripts in the package.json

Conclusions

Setting up a development environment is not easy, it always depends on what you need. There is always the option to look for a boilerplate application and modify according to your needs. I have found that this small configuration worked perfect to me but you will need to add/remove some dependencies if you don’t need them.

You can find a boilerplate using this configuration at https://github.com/densitylabs/typescript-react-electron-boilerplate

Did you already have experience with The Holy Trinity? Would you change or add something else?

    "experimentalDecorators": true,
    "lib": ["es6", "dom"],
    "module": "es6",
    "moduleResolution": "node",
    "sourceMap": false,
    "target": "es5",
    "jsx": "react",
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "baseUrl": ".",
    "paths": {
      "@app/*": ["src/*"],

  },
  "exclude": [
    "**/*.spec.ts",
    "node_modules",
    "vendor",
    "public"
  ],
  "compileOnSave": false
}

This may change depending on your folder structure, I like to put all my code inside a src/ directory and I also wanted to avoid the relative path hell

import Component from '.../.../../../component';

So I just declared an absolute path

....
  "paths": {
      "@app/*": ["src/*"],
    }
...

React

yarn add react react-dom

Given that you already installed TypeScript, you might want to install @types/react as well

yarn add @types/react @types/react-dom -D

Webpack

You just installed The Holy Trinity dependencies but you still need to compile your TypeScript/React code and generate a bundle file that Electron can read, that's a task for Webpack.

You just need to install a “few” dependencies, you probably won’t need some of them.

yarn add webpack webpack-cli copy-webpack-plugin css-loader file-loader postcss-loader sass-loader style-loader ts-loader url-loader html-webpack-plugin precss autoprefixer -D

Then you must configure Webpack, this is the webpack.config.js that worked for me but it might change depending on your project folder structure.

const webpack = require('webpack');
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');

const mode = process.env.NODE_ENV || 'development';

module.exports = [
  {
    mode,
    entry: {
      electron: path.resolve('./src/electron.ts'),
    },
    target: 'electron-main',
    node: false,
    module: {
      rules: [
        {
          test: /\.ts$/,
          include: /src/,
          use: [{ loader: 'ts-loader' }]
        }
      ]
    },
    output: {
      path: path.resolve(__dirname, 'build'),
      filename: '[name].js'
    },
    resolve: {
      extensions: [ '.tsx', '.ts', '.js' ],
      alias: {
        '@app': path.resolve(__dirname, 'src/')
      }
    }
  },
  {
    mode,
    node: false,
    entry: {
      index: path.resolve('./src/index.tsx'),
    },
    target: 'electron-renderer',
    module: {
      rules: [
        {
          test: /\.ts(x?)$/,
          include: /src/,
          use: [{ loader: 'ts-loader' }]
        },
        {
          test: /\.css$/,
          use: ['style-loader', 'css-loader']
        },
        {
          test: /\.(scss)$/,
          use: [{
            loader: 'style-loader',
          }, {
            loader: 'css-loader',
          }, {
            loader: 'postcss-loader',
            options: {
              plugins: function () {
                return [
                  require('precss'),
                  require('autoprefixer')
                ];
              }
            }
          }, {
            loader: 'sass-loader'
          }]
        },
        {
          test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
          issuer: {
            test: /\.jsx?$/
          },
          use: ['babel-loader', '@svgr/webpack', 'url-loader']
        },
        {
          test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
          loader: 'url-loader'
        },
        {
          test: /\.(jpe?g|png|gif)$/i,
          loader: 'url-loader'
        }
      ]
    },
    resolve: {
      extensions: [ '.tsx', '.ts', '.js' ],
      alias: {
        '@app': path.resolve(__dirname, 'src/')
      }
    },
    output: {
      path: path.resolve(__dirname, 'build'),
      filename: '[name].js'
    },
    plugins: [
      new HtmlWebpackPlugin({
        template: './src/index.html'
      }),
      new CopyWebpackPlugin([
        { from:'src/assets',to:'assets' }
      ])
    ]
  },
]

If you are familiarized with Electron, you might know that it has a main and render process, so I decided that the best would be writing a configuration for each process.

We need to specify an entry point and a target for each process.

Main process

entry: {
      electron: path.resolve('./src/electron.ts'),
    },
    target: 'electron-main',

Render process

entry: {
      index: path.resolve('./src/index.tsx'),
    },
    target: 'electron-renderer',

That's it!!! You should be able to compile your TypeScript code and execute your Electron application by just running:

./node_modules/webpack/bin/webpack.js --config ./webpack.config.js
electron ./build/electron.js

The best would be write this as scripts in the package.json

Conclusions

You can find a boilerplate using this configuration at https://github.com/densitylabs/typescript-react-electron-boilerplate

Did you already have experience with The Holy Trinity? Would you change or add something else?

Electron, TypeScript & React - The Holy Trinity

I decided to create this blog post to share with you what I called The Holy Trinity.

Project Setup

First of all you need to start your project by running

yarn init

npm init

After answering the questions that were prompted, it's time to install the dependencies that you need.

Project structure

This is the folder structure that I used, not sure if it is the best but it worked for me

webpack.config.js
tsconfig.json
package.json
src/
  assets/
  electron.ts
  index.tsx
  index.html

Electron

Installing Electron is the easiest task, all what you need is to install the dependency and add it to your package.json

yarn add electron -D

You can corroborate that Electron was installed correctly by creating a Hello World, just create a new file index.js

const { app } = require('electron')

app.on('ready', () => {
  console.log('Hello world');
});

And then just run

electron index.js

TypeScript

In order to setup TypeScript all what you need is just to install the dependencies

yarn add typescript -D

After that you need to write your tsconfig.json. This worked like a charm for me

{
  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es6", "dom"],
    "module": "es6",
    "moduleResolution": "node",
    "sourceMap": false,
    "target": "es5",
    "jsx": "react",
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "baseUrl": ".",
    "paths": {
      "@app/*": ["src/*"],
    }
  },
  "exclude": [
    "**/*.spec.ts",
    "node_modules",
    "vendor",
    "public"
  ],
  "compileOnSave": false
}

....
  "paths": {
      "@app/*": ["src/*"],
    }

React

yarn add react react-dom

Given that you already installed TypeScript, you might want to install @types/react as well

yarn add @types/react @types/react-dom -D
