[docs]: improve slot scope auto exposing "params" behaviour #1924



Copy link

@renatodeleao renatodeleao commented Dec 27, 2022

Hello again 馃憢
I had a bunch of specs that rely on the previous VTU1 behaviour, where slot scope was auto-exposed as a props object for string templates and realised that in VTU2 they are exposed as params

if (!hasWrappingTemplate) {
template = `<template #default="params">${template}</template>`

While VTU1 docs mention that behaviour, VTU2 docs didn't explicitly do it as the only example provided used an <template #scope="params"> which doesn't document the implicit behaviour if not providing a wrapping <template> tag.

Update both main docs and migration guide, since I believe this is a common bump in the road while migrating codebases.

As always feel free to edit the writing style and examples to suite the rest of the docs.
Cheers 鉁岋笍

The only example provided used an explicit #default="params", but it doesn't mention that if you don't explicitly wrap it, the slot scope becomes also available as params. In VTU1, they were exposed as props, so i think it's better to be explicit about it.
