Advanced tools
MJML provides a validation layer that helps you building your email. It can detect if you misplaced or mispelled a MJML component, or if you used any unauthorised attribute on a specific component. It supports 3 levels of validation:
skip
: your document is rendered without going through validationsoft
: your document is going through validation and is rendered, even if it has errorsstrict
: your document is going through validation and is not rendered if it has any errorBy default, the level is set to soft
.
When using the mjml
command line, you can add the option -c.validationLevel
or --config.validationLevel
with the validation level you want.
Set the validation level to
skip
(so that the file is not validated) and render the file
mjml --config.validationLevel=skip template.mjml
Alternatively, you can just validate file without rendering it by add ing the --validate
option
mjml --validate template.mjml
In Javascript, you can provide the level through the options
parameters on mjml2html
. Ex: mjml2html(inputMJML, { validationLevel: 'strict' })
strict
will raise a MJMLValidationError
exception. This object has 2 methods:
getErrors
returns an array of objects with line
, message
, tagName
as well as a formattedMessage
which contains the line
, message
and tagName
concatenated in a sentence.getMessages
returns an array of formattedMessage
.When using soft
, no exception will be raised. You can get the errors in the object returned by mjml2html
. It is the same object returned by getErrors
on strict mode.
