Programmatically run knex seed:run

Question

To seed a database, knex says to run the following script:

$ knex seed:run

I was looking for a way to do this programmatically (ie in my javascript code). I have the following that compiles without any problems but it only returns a promise and doesn't actually do the seeding:

const knexInstance = require('knex')(config);
knexInstance.seed.run()

Any help appreciated.

Knex is using bluebird under the hood, so to run seed, you need to wait for promise to be finished.

Waiting for promise can be done by standard JavaScript await.

await knexInstance.seed.run();
