Introduction
ERB stands for Embedded Ruby, and is used to insert Ruby variables inside templates, e.g. HTML and YAML. ERB is a Ruby class that accepts text, and evaluates and replaces Ruby code surrounded by ERB markup.
Syntax
- <% number = rand(10) %> this code will be evaluated
- <%= number %> this code will be evaluated and inserted into the output
- <%# comment text %> this comment will not be evaluated
Remarks
Conventions:
- ERB as a template: Abstract business logic into accompanied helper code, and keep your ERB templates clean and readable for people without Ruby knowledge.
- Append files with
.erb: e.g..js.erb,.html.erb,.css.erb, etc.
