sequelize-cli-helpers

A power-up for Sequelize at the command line.

Intro

Sequelize is a powerful ORM, and while sequelize-cli is helpful, in our workflow we have found several gaps. sequelize-cli-helpers is our power-up for improving our Sequelize workflow, especially for generating migrations and models.

This is not a full replacement for sequelize-cli. For performing and managing migrations, you will still need that tool.

Usage

• $ sequelize-cli-helpers <command>

Commands

Commands:
  gen:migration:table  generates a Sequelize migration to create a table
  touch                generates a file name and touches the empty file

Options:
  --help     Show help                                                 [boolean]
  --version  Show version number                                       [boolean]

Configuration

You can configure sequelize-cli-helpers for your project with a .sequelizeclihelpersrc file in the root of your project.

The .sequelizeclihelpersrc can overwrite any part of the configuration.

Here is an example of what you can do:

module.exports ={
  dateFormat: 'YYYYMMDDHHmmss',   // format of date string to be used in file naming
  fileExtension: 'js',
  fileNameFormat: 'N.D',          // format of file name to be generated, see below
  forceConfirmation: true,        // forces prompt for confirmation of some values
  matchNumberOn: 'N',             // if using a 'N' format in your string, this determines how to calculate the next number
  numberPaddedLength: 4,          
  separator: '-',                 // separator to use between each part of the name, e.g. `20190311133906-create_table_hufflepuffs.js`
  paths: {
    templates: path.resolve('./db/templates/'),  // path to your custom templates, see below
  }
};

File Name Formats

One of the uses of sequelize-cli-helpers is to control the naming of your sequelize-cli migration, seeders, and model files. Not all teams want to use the default sequelize-cli behavior, and this tool provides complete control of that naming, and makes part of it automatic.

The file name format is configured in the .sequelizeclihelpersrc file, and is a string such as 'Tz.D'.

The following format parts can be utilized:

• Tz a date string configured per the dateFormat
• N a number string left padded with zeroes to numberPaddedLength
• D a description
• G git branch info pulled from your repo, the branch name is parsed and the text of the branch name after the first / will be used.
• R a random string

You can order the file name format in any order excepting that a date Tz or a number N must come first.

The number will be auto-generated based on other files with numbers in their names and filted by the date format to match on, the matchNumberOn. If matchNumberOn === 'N', then it will consider all files of the same format with a number; if matchNumberOn === 'G', the existing files will be filtered on by git info; and so on. From these filtered lists, the number of the last file name in the list will be used to generate the next number.

Custom Templates

sequelize-cli-helpers has a default template to create a Sequelize table migration, see migration_create_table.hbs. You can provide your own for your project so long as you provide a path.templates in your .sequelizeclihelpersrc file, and have a template of the same name (migration_create_table.hbs) in that path, and the template must handle the same provided context keys (see our migration file, must handle tableName, attributes).
