Confused about purpose of the default property for inputs in manifest.yml

Is the “default” property of inputs supposed to be available in the operation of a plugin?
While developing a plugin… unless I explicitly define an “input” value in the netlify.toml, the “input” is undefined in plugin code execution. Even if the manifest.yml has a default.

So is the manifest.yml just for documentation?
If so, why do so many existing plugins list defaults for inputs, but never set a default in their plugin code?

Hey @moop-moop,
The manifest.yml is not just for documentation. I found Tara Manicsic’s tutorial on this really helpful:


And you probably already know about this repo but dropping it here for future readers of this post:

That said, it is surprising that you would get undefined if you set a default value in the manifest.yml. Can you share your repo or a deploy log?

Hi @moop-moop,

As @jen mentioned, if you set a default for one of your inputs in your manifest.yml, and a user of your plugin is not defining that input, Netlify will use the default value instead.

If this is not the behavior you are experiencing, please share a link to your plugin (if public) and a link to a deploy. Thanks!

I made it public @jen , it was started from your template @ehmicky

This is great @moop-moop!

Would you like to submit this plugin to our list of plugins so it shows up in the Netlify app? We are currently adding some guidelines here.

I will eventually @ehmicky, but need to solve the multiple manifest.yml issues I am having first.
No defaults still from manifest.yml and latest netlify-cli version causing new not found problems for me.

Which new problems are you experiencing? We can help fix this.

I never solved the manifest.yml defaults not being available, but now the new issue is a bigger problem.
New issue:
Started after your last update of netlify-cli and @netlify/build

#9

Oh, I am actually looking into that problem. It got reported here as well: https://github.com/netlify/build/issues/1373
Thanks for raising this up.

#10

This should be fixed now.
Please let us know if you’re still experiencing any problems. Thanks!

Seems to be good, thanks.
My manifest.yml defaults are available.
