Miniparser is a Ruby gem that takes code as input (HTML, JavaScript, or CSS), determines the code language, validates it, and then minifies it. It returns whether the code is valid or not, and if valid, provides the minified code.

Add this line to your application's Gemfile:

gem 'Miniparser'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install Miniparser


Miniparser provides two main methods to process either a file or a string containing HTML, JavaScript, or CSS code.

Processing a File

You can process a file by calling the type_file method and passing the file path as an argument:

result = Miniparser::Processor.type_file('path/to/yourfile.html')

Processing a String

You can process a string containing code by calling the type_string method:

result = Miniparser::Processor.type_string('<html><head></head><body></body></html>')

Both methods return a hash containing the validation status, any errors, and the minified code if the input was valid:

  valid: true or false,
  errors: "Error message if any",
  minified_code: "Minified code if valid"
