Vue 3 + Electron + Sqlite + Sequelize

POC for Electron app with Vue 3 frontend and persisted database with SQlite.

Setup

Inside project root folder

note: I prefer using yarn as npm is highly unstable with electron and vue integration

yarn 

yarn electron:serve

To Build App for OS executables

yarn electron:build

File Structure

• The project is a normal Vue CLI project. So the file structure is pretty familiar.
• The electron builder plugin adds a new file src/background.ts , this serves as the entry point of the electron app.
• src/data.db In project SQlite 3 database for testing.
• getdb.ts Initiates the Sequelize instance for using the database.
• main.ts entry of vue app. It creates the vue instance and mounts the app.

Where to code ?

• For adding pages/views for electron app go to > src/views.
• For adding components to be used i Vue pages/views go to > src/components
• To create new app window / or any electron stuff go to > src/background.ts
• For working with database i.e. creating models for sequelize go to > src/getdb.ts

Config Files

• tsconfig.json for configuring typescript.
• vue.config.js Vue config. Not recommended to change anything in this file.

A brief note on Sequelize

• Sequelize is a promise based ORM. So using it is pretty easy.
• Whe using sequelize we don't have to create tables as it creates and syncs tables according to the defined models.
• Sequelize models are a abstaction of the data schema or the table schema of a db. So instead of using SQL queries for creating tables we can make sequelize to do that by using models.
• A sample model User is defined in src/getdb.ts. Learn more about sequelize Models

// a sample model USer
const User = sequelize.define('User', {
    firstName: {
        type: DataTypes.STRING,
        allowNull: false
    },
    lastName: {
        type: DataTypes.STRING
    },

}, {
});

• SQL queries are replaced by sequelize model queries .

// sample query for model User
// inside an async function

User.findAll().then((res)=>{
	console.log(res)
}).catch(err=> console.log(err))

Lean more about model Queries here

• More about Sequelize can be found in their Docs. Not that good but functional.

Notes

• Usage with Vuex is not recommended as it causes the db process to stop on reload.

Known Bugs

• There are no known bugs as the build was successful with no errors.
• To report a bug create an issue.
