Rails & Trix: Add Underline, Superscript, and Subscript

Rails & Trix: Add Underline, Superscript, and Subscript

This guide will walk you through adding some extra features such as the ability to underline your text, or enhance your content by adding superscripts or subscripts for annotations or Math equations.

Prerequisites: Instruction guide assumes that you have created a Rails application and installed ActionText.

What will you learn:

import { Controller } from "@hotwired/stimulus"
import SignaturePad from 'signature_pad'
export default class extends Controller {
static targets = ["canvas", "input"]
connect() {
this.signaturePad = new SignaturePad(this.canvasTarget)
this.signaturePad.addEventListener("endStroke", this.endStroke)
this.resizeCanvas()

ActiveJob as Service Worker
# ActiveJob natively captures constructor arguments in an `@arguments` instance variable
# which is also exposed as an `arguments` property on each job instance.
#
# Calls to `perform_now` and `perform_later` both forward arguments to the constructor.
#
# For example, all of these invocation styles work.
#
# result = DoStuffJob.new("foobar").perform # sync
# result = DoStuffJob.new.perform("foobar") # sync
# result = DoStuffJob.perform_now("foobar") # sync
