gatsby-plugin-feed requires creating slugs for pages

[johnreynoldsventure]

This is probably obvious to many, but while adding gatsby-plugin-feed to my site I discovered that you must add slugs to your MarkdownReact nodes.

The documentation for how to do this is very clear: https://www.gatsbyjs.org/docs/creating-slugs-for-pages/

What wasn't clear (to me) was that this was a dependency for gatsby-plugin-feed.

I hope this helps others...

The plugin shouldn't work this way. You should pass into the configuration which field to use does the slug. Would you be interested in working on a PR for this?

I'd love to help more Kyle, but I fear I don't know enough - I'm just getting started with gatsby.
I started with the gatsby tutorial, and have been added functionality as I need it. Likely my problems are due to me missing a step or two along the way rather than anything fundamental.

Your are right. :) gatsby-plugin-feed require slug by default.
=> here is the code where plugin use slug to define each page url.

But you can costomize it by passing option into gatsby-config.js.

In my example I try to change default site url from https://example.com/${slug} to https://example.com/posts/${slug} in feed.
=> here is the code.

I'll like to work on a PR @KyleAMathews. Can you point me on the write direction?

I think this should be fixed by updating the docs stating that the default serializer requires a slug field, rather than any change to the plugin.

[DSchau]

@VGoose we actually did that recently -> https://github.com/gatsbyjs/gatsby/tree/master/packages/gatsby-plugin-feed#how-to-use

(We don't note what you need to do to use the internal serialize, just that we recommend you write your own!)

[VGoose]

@DSchau any reason to not be explicit about the requirements of the default serializer? The issue was opened because it wasn't clear.
