Query nodes built by transfomers based on gatsby-source-filesystem sourceInstanceName

[djhi]

Hi!

We use gatsby-transformer-remark and gatsby-transformer-sharp alongside the gatsby-source-filesystem plugin.

We currently filter the allMarkdownRemark query with a regex on the fileAbsolutePath property (as also explained in #1634). However, this workaround does not apply to the gatsby-transformer-sharp plugin.

Wouldn't it be nice to always have the sourceInstanceName property in the filter ? As far as I understand gatsby, this should always be available for any source plugin ?

In retrospect it was a mistake adding that field to gatsby-transformer-remark and will be removed in the future as the transformer shouldn't know or care what the source of the markdown is.

What you want to do instead is just query allFile filtering on the source and then select childImageSharp, etc.
