Eager loading nested matrix blocks

[leevigraham]

We've recently switched form NEO to a native Matrix setup and I wanted some clarification on eager loading.

The docs don't have a specific example for Matrix fields: https://craftcms.com/docs/5.x/development/eager-loading.html

My Matrix field has a bunch of Entry Types… some of those Entry Types have relationships.

In the case of the container block it contains the block builder matrix field (recursive):

In the majority of cases I would like all the children blocks of the matrixContentBlocks to be eagerly loaded… ideally with any relationships fields.

Is this possible to do in a one liner? Maybe with .eagerly()?

I should also mention I'm using .render() with _partials templates for all Entry Types.

There’s no “one-liner” solution, but you can have all of your queries eager-loaded by adding .eagerly() to each element query.
