After generating the Rails scaffolding for my “Conversation” model, it was just a few steps to do inline editing:

1. Modify conversations/_conversation.html.erb to wrap it in a turbo-frame
2. Modify conversations/_form.html.erb partial to wrap it in the same turbo-frame so that the form will replace the displayed title
3. Add a tiny bit of stimulus to enable submit on enter/blur and to enable discard with Escape

And this is my full inline_edit_controller.js for reference:

import { Controller } from "@hotwired/stimulus"

export default class extends Controller {
  static targets = [ "input" ]

  connect() {
    this.originalText = this.inputTarget.value
    this.focusInput()
    this.cursorToEnd()
  }

  focusInput() {
    this.inputTarget.focus()
  }

  cursorToEnd() {
    this.inputTarget.selectionStart =
      this.inputTarget.selectionEnd =
        this.inputTarget.value.length
  }

  submitForm() {
    if (this.inputTarget.disabled) return

    this.element.requestSubmit()
    this.inputTarget.disabled = true
  }

  abort() {
    this.inputTarget.value = this.originalText
    this.submitForm()
  }
}
