Using local database after electron build

Hey all. I’m currently using Electron 5.0.1, Vue 2.6, and The Electron Builder v1.3.1. I’m having trouble getting SQLite to work when I’m trying to build a MacOS or Windows app.

Here’s what my vue.config.js looks like:

module.exports = {
  css: {
    loaderOptions: {
      sass: {
        data: `
          @import "@/styles/main.scss";
        `,
      },
    },
  },
  configureWebpack: {
    externals: {
      sequelize: "require('sequelize')",
    },
  },
  pluginOptions: {
    electronBuilder: {
      externals: ['sequelize'],
      builderOptions: {
        extraResources: ['src/data.db'],
      },
    }
  },
};

and Here’s how I connect via my db:

import Sequelize from 'sequelize';
import Component from '@/models/component';
import Element from '@/models/element';
import Kiosk from '@/models/kiosk';
import Page from '@/models/page';
import path from 'path';

const isBuild = process.env.NODE_ENV === 'production';
const pathToDbFile = path.join( // eslint-disable-next-line
  (isBuild ? __dirname : __static),
  (isBuild ? '../../' : ''),
  '../src/data.db',
);

// setup the connection to make sure it works
const sequelize = new Sequelize({
  dialect: 'sqlite',
  storage: pathToDbFile,
  logging: (process.env.NODE_ENV !== 'production') ? console.log : false,
  define: {
    timestamps: false,
    underscored: true,
  },
});

const db = {};

// test for the connection
if (process.env.NODE_ENV !== 'production') {
  sequelize.authenticate()
    .then(() => {
      console.log('Connection has been established.');
    })
    .catch(console.error);
}

db.Component = Component.init(sequelize);
db.Element = Element.init(sequelize);
db.Kiosk = Kiosk.init(sequelize);
db.Page = Page.init(sequelize);

Object.keys(db).forEach((modelName) => {
  if (db[modelName].associate) db[modelName].associate(db);
});

db.Sequelize = Sequelize;
db.sequelize = sequelize;

export default db;

Any idea what’s going on?

Use this:

const pathToDbFile = path.join(
  // eslint-disable-next-line
  isBuild ? __dirname : __static,
  '../src/data.db',
);

not sure why the path changed, but this works now.

@j-nguyen Have you encountered this error?

Please install sqlite3 package manually

externals: ['sequelize'] in the vue.config.js works for me
