Hello I found this repo in reddit and have glanced at the source code.
I've tried the wasm example to quickly go thru a few templates.

While trying to render this template https://mjml.io/try-it-live/templates/austin
the output becomes 'undefined' which I know means that it has found a tag that mrml
does not recognize but the error is not very user friendly.

I'm new to mjml and have no idea which tags are valid so I don't know how to begin to debug this. Could there be a way to ignore unknown tags and continue rendering the known tags? maybe by ignoring all the child xml nodes.

More verbose output could also be helpful.

Several things:

  • <mj-style inline="inline"> is not yet implemented
  • <mj-attributes> is not yet implemented

I'm working on it, it's in progress ;)

is not yet implemented

Hi @jdrouet

Thanks for creating this library. I see that there's an issue for mj-attributes that is marked as done. Has this been released?

@devnacho The mj-attributes bug should be fixed, but <mj-style inline="inline"> are not yet implemented.

The (much slower) node cli has an option to provide a validation method when compiling templates.

Adding a validation option for the render subcommand seems like it would be useful for production use where we would want to render the template even if there was an erroneous tag/attribute in the markup.

Possible validation options:
strict: (default) fails/throws on any validation failure
warnings: possibly injects comments <!-- Invalid tag on like 45 column 15 --> right below the <head> tag for validation errors but renders without failing
silent: renders without any validation notices

The latest refactoring of mrml has been made with that purpose. That's probably the next big thing I want to tackle.
But the error messages should already be improved.
