I love love love the speed at which you talk. All others talk too slowly. Takes forever to get to the point. THANK YOU!

This is absolutely fantastic. Great, lively speed of delivery, and easy to understand, with comprehensible use case scenarios. Many thanks.

Chaim, you are the only one who always helps me in the so deep combinations of things where resources lack. Thanks as always

[@CodingWithChaim]

You are most welcome

I was struggling with migrations in knex, this tutorial really helped me to understand the migrations. Thank you so much !!!

[@CodingWithChaim]

Glad it helped!

[@leandro3710]

Even not being a native speaker I could understand everything, nice job!

[@user-iq1km3bd9s]

[@iva1389]

finally! appropriate speedflow.

[@RanjitSingh-wy4ku]

nice explanation. I had to check if I was playing it at 1.5x speed :-)
What could be other alternatives to Knex library?

[@shivanshpratap3624]

Any ORM that supports migrations.

[@fredianriko5648]

thank you ben saphiro

[@ehsanShirzadi]

This is the first video tutorial, I didn't have to set the speed to 1.5X :D

[@evanilsonp.8183]

Jesus you talk so fast. But i understand well haha thsnks man your video was good

[@_slier]

what is the differences between knex and db-migrate?

[@ibadshaikh2215]

By default 1.5x

[@william3588]

With migrations
What about removing a column from a table?
Should I remove it on the up and down function?
exports.up = function (knex) {
return knex.schema.table('user', (table) => {
table.dropColumn('fullname');
});
};
exports.down = function (knex) {
knex.schema.table('user', (table) => {
table.dropColumn('fullname');
});
};

[@CodingWithChaim]

Great question! You want the down to do the opposite of the up, so if the up is removing the column, I would make the down add it back. I like to think of it as an undo.

[@asdiasx]

Great contents! But too fast for non natives english speakers like me... 😐

[@TheNepalikhukuri]

semi bald eminem is lit, thank you 😀

[@supernenechi]

I actually had to check if I was playing at 1.5x speed. Man, you speak quickly. Otherwise good video

[@ruslan762]

Nice explanation but it seems like this guy was working on Texas auctions in the past )))

[@igorordecha]

Had to watch at 1.5x speed. You're not even talking at rap god's fast verse-like speed. If i was subscribed I would unsubscribe rn.
