Script to create schema.sql from sequelize sync logs. This will only help with getting started there must be some other changes to do manually for using with graphile-migrate.

sequelize-to-graphile-migrate.js

import fs from 'fs'

export function getLogger (path) {
  const stream = fs.createWriteStream(path)

  process.on('beforeExit', () => stream.close())

  return msg => {
    const _ = msg + ''
    if (!/ select /i.test(_)) {
      stream.write(
        _.replace('Executing (default): ', '\n').replace(/;/g, ';\n')
      )
      // the rest formating can be done with pg formatter or
      // with some online free tools. I used https://sqlformat.org
    }
  }
}

/*
* After sequelize is synced the rest can be edited manually in schema.sql
* export const sequelize = new Sequelize(database.connectionString, {
*   // ...
*   logging: getLogger('./schema.sql')
* })
*/
