Blockstrapper is a plugin for WordPress I have begun development on.
Noticing a need for the ability to add Bootstrap styles to the Gutenberg editor I started coding this solution for all WordPress users.
blockstrapper.r–j.ca uses the new Twenty Nineteen theme, and Blockstrapper appears to have limited functionality with it.
Blockstrapper will be implemented across this entire website (r–j.ca) once a stable release has become available. View the Blockstrapper git.
