Still having problems with db-migrate and ESM node projects...

Current behavior

I’m still having trouble running db-migrate in an ESM project / module (on the latest beta 1.0.0-beta.18). I keep receiving this error:

[ERROR] Error [ERR_REQUIRE_ESM]: require() of ES Module /home/kyle/web/server/migrations/some-migration.js from /home/kyle/web/server/node_modules/db-migrate/lib/file.js not supported. Instead change the require of some-migration.js in /home/kyle/web/server/node_modules/db-migrate/lib/file.js to a dynamic import() which is available in all CommonJS modules.

Minimal reproduction of the problem with instructions

My migration file looks something like this:

const Table = require('../dist/database/tables/SomeTable.js').SomeTable;
const table = new Table();

...

exports.up = function (db) {
  return table.up(db);
};

...

I’ve also tried swapping the first line for something like this:

import {SomeTable} from '../dist/database/tables/SomeTable.js';
...

but neither have worked. Does it have something to do with me importing a file into the migration file? The imported table is from an ESM module that also has dependencies to other ESM (local) projects.

I’ve recently switched my projects to ESM, so let me know if I’m missing something.

Environment

db-migrate version: 1.0.0-beta.18
plugins with versions: none
db-migrate driver with versions: db-migrate-mysql 2.2.0

Additional information:
- Node version: 16.16.0
- Platform:  Ubuntu Server 18.04.6

Edit: Code blocks

b/c this has nothing to do with us. We support for db-migrate, not for understanding nodejs.

as a little favor:

Well please read the models docs about esmodules for that.

Thanks for the quick response. However, I’m still getting the same error even with the package.json file in the migrations folder Now, if my migration file looks like this:

const Table = require(‘…/dist/database/tables/SomeTable.js’).SomeTable; const table = new Table();

…

exports.up = function (db) { return table.up(db); };

…

I get the same error as above (Error [ERR_REQUIRE_ESM]) But if my migration file looks like this:

import {SomeTable} from ‘…/dist/database/tables/SomeTable.js’; …

I get this error:

[ERROR] unhandledRejection [ERROR] /home/kyle/web/EbayServer/migrations/some-migration.js:3 import {SomeTable} from ‘…/dist/database/tables/SomeTable.js’; ^^^^^^

SyntaxError: Cannot use import statement outside a module

Is there something else I need to do? Thanks! — Reply to this email directly, view it on GitHub, or unsubscribe. You are receiving this because you modified the open/close state.Message ID: @.***>
