mjml-validator

MJML provide a validation layer that help you building your email. It can detects if you misplaced or mispelled an element, same with attributes. It supports 3 level of validation :

• skip : your document is not validated at all
• soft (default) : your document is validated, but even if it has errors it will be rendered
• strict : your document is validated but if it has errors it will not render anything

In cli

In mjml command line you can add a -l or --level with validation level you want. Ex: mjml -l strict -r my_template.mjml

In Javascript

In Javascript you can provide the level through the options params on MJMLRenderer. Ex: new MJMLRenderer(inputMJML, { level: strict })

strict will raise an MJMLValidationError exception. This object has 2 methods:

• getErrors that returns you an array of object with line, message and tagName and a formattedMessage.
• getMessages that returns you an array of formattedMessage.

soft will not raise an exception, instead you can find errors inside the object returned by render methods : errors. It the same object returned by getErrors on strict mode
