How to write a seek/keyset pagination query using sequelize for postgres dialect? - postgresql

Question

I have a raw SQL query written in pg-promise that looks as shown below
SELECT
f.feed_item_id,
pubdate,
link,
guid,
title,
summary,
author,
feed_id,
COALESCE(likes, 0) AS likes,
COALESCE(dislikes, 0) AS dislikes,
COALESCE(bullish, 0) AS bullish,
COALESCE(bearish, 0) AS bearish,
tags
FROM
feed_items f
LEFT JOIN
feed_item_likes_dislikes_aggregate l
ON f.feed_item_id = l.feed_item_id
LEFT JOIN
feed_item_bullish_bearish_aggregate b
ON f.feed_item_id = b.feed_item_id
WHERE
(
pubdate,
f.feed_item_id
)
< ($1, $2)
ORDER BY
pubdate DESC,
f.feed_item_id DESC LIMIT $3
How can I rewrite this query using sequelize?
My current attempt comes like this
FeedItem.findAll({
attributes: [
'feedItemId',
'pubdate',
'link',
'guid',
'title',
'summary',
'author',
'feedId',
'tags',
[sequelize.fn('COALESCE', sequelize.col('bullish'), 0), 'bullish'],
[sequelize.fn('COALESCE', sequelize.col('bearish'), 0), 'bearish'],
[sequelize.fn('COALESCE', sequelize.col('likes'), 0), 'likes'],
[sequelize.fn('COALESCE', sequelize.col('dislikes'), 0), 'dislikes'],
],
include: [{
model: FeedItemBullishBearishAggregate,
attributes: [],
}, {
model: FeedItemLikesDislikesAggregate,
attributes: [],
}],
order: [
['pubdate', 'DESC'],
['feedItemId', 'DESC']
],
limit: 1
}).then(a).catch(b)
How do I put that where condition in the above findAll expression?
