Escaping word character selector in Gatsby GraphQL regex filter
I am currently using Gatsby to build a documentation site for a component library that I have developed. I have installed the Transformer-Remark plugin which creates javascript objects for each markdown file within my site's structure.
As the site is for documentation, I have a Component detail page which outlines how a component can be used by a consumer and the majority of the content of this page is derived from the README.MD of the corresponding package on NPM.
On the left hand side of this page is a dynamic menu which lists the components I have created. The menu makes use of a GraphQL query within a custom Gatsby template to split the components into 3 categories based on a RegEx filter of their fileAbsolutePath like so:
export const pageQuery = graphql`
query($path: String!)
pageData:
markdownRemark(fields: slug: eq: $path )
html
fields
slug
title
fileAbsolutePath
atoms:
allMarkdownRemark(sort: order: ASC, fields: [fields___title], limit: 1000, filter: fileAbsolutePath: regex: "/dl-atoms-(w+)/README/")
edges
node
fields
slug
title
molecules:
allMarkdownRemark(sort: order: ASC, fields: [fields___title], limit: 1000, filter: fileAbsolutePath: regex: "/dl-molecules-(w+)/README/")
edges
node
fields
slug
title
organisms:
allMarkdownRemark(sort: order: ASC, fields: [fields___title], limit: 1000, filter: fileAbsolutePath: regex: "/dl-organisms-(w+)/README/")
edges
node
fields
slug
title
`;
However when I try to run Gatsby Develop I get the following error:
Syntax Error: Invalid character escape sequence: w.
I have tried adding a second backslash before the string in question to escape it but this doesn't work.
Is there a special way of escaping certain characters in RegEx filters in GraphQL?
Edit:
I should add that the same RegEx works fine on this RegEx testing site:
https://regexr.com/436ep

It should beregex: /dl-atoms-(w+)/README/

That leads to a different error: Syntax Error: Cannot parse the unexpected character "/". Do I then need to go through and escape the opening forward slash, etc. I'm pretty sure I copied the syntax from the Gatsby or GraphQL documentation so I was under the impression the quotes are required ?!

Well, it is strange as it seems"/dl-molecules-(\w+)/README/"
should work. Maybe theREADME
must match the whole string, try"/dl-molecules-(\w+)/.*README.*/"
