Node 13.x is not supported

What you are doing?

Nodejs 13.x enable esm module by default https://nodejs.org/api/esm.html

> npx sequelize --options-path ./.sequelizerc.js db:migrate:undo:all && npx sequelize --options-path ./.sequelizerc.js db:migrate

Must use import to load ES Module: d:\...\.sequelizerc.js
require() of ES modules is not supported.
require() of d:\...\.sequelizerc.js from d:\...\node_modules\sequelize-cli\lib\core\yargs.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename .sequelizerc.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from d:\...\package.json.

So I rename .sequelizerc.js to .sequelizerc.cjs and change all migration files extension to .cjs and get:

File: 00001-MyModel-createTable.cjs does not match pattern: /\.js$/

What do you expect to happen?

Do not force cjs module, things should just work with esm modules.

What is actually happening?

esm modules are not supported

Is there any fix for this issue so far. Having similar issue while running the command npx sequelize db:migrate. Using Node 14 with “sequelize”: “^6.6.2”,“sequelize-cli”: “^6.2.0”

Node 8 is end of life so Node 10 is the current active LTS and dynamic import was introduced in Node 9.7. So with a major version bump, it could be possible to just replace require() by import()
