Custom template

Template syntax

To create your custom template, use simple lodash template syntax:

'use strict';

// Import dependencies.
import { Sequelize, DataTypes } from 'sequelize';

// Declare config.
<% if (sequelizeConfig.file) { %>
  const config = require('<%= sequelizeConfig.file %>');
<% } else { %>
  const config = {
  <% Object.keys(sequelizeConfig.env).forEach(function(key){ %>  <%= key %>: <%=sequelizeConfig.env[key]%>
  <% }); %>};
<% } %>

// Create new sequelize instance and export
export const sequelize = new Sequelize(config.database, config.username, config.password, config);

// Export list of models
<% models.forEach(function(modelData){ %>
  export const <%= modelData.name %> = require('<%= modelData.path %>')(sequelize, DataTypes);
<% }); %>

Available data in templates

{
  sequelizeConfig: {
    // it will be used firstly, if config option is setted
    file: 'path/to/your/database/config.js',
    // default options to generate config, based on ENV parameters
    env: {
      database: `process.env.DB_DATABASE,`,
      username: `process.env.DB_USERNAME,`,
      password: `process.env.DB_PASSWORD,`,

      port: `process.env.DB_PORT || 3306`
    },

      { name: 'User', path: '../models/user.js' }
      { name: 'Profession', path: '../models/profession.js' }
    ]
