cannot migrate and run seed in production. The knex tries to run a ts file and it fails. Console error:

Cannot use import statement outside a moduleD:\web-projects\product-feedback\dist\src\db\migrations\20211215210852_initial.d.ts:1

Answer 1

Edit your knex config options to only run.js files in your production. You can achieve this with loadExtensions: ['.js'], see bellow:

production: {
        client: 'pg',
        connection: pgConnection,
        pool: {
            min: 2,
            max: 10,
        },
        migrations: {
            directory: './src/db/migrations',
            loadExtensions: ['.js'],
        },
        seeds: {
            directory: './src/db/seeds',
            loadExtensions: ['.js'],
        },
    },
