Rendering defaults

Superglue typically requires 3 templates.

app/views/
  posts/
    index.html.erb # duplicated
    index.jsx
    index.json.props
  users/
    index.html.erb # duplicated
    index.jsx
    index.json.props

Use use_jsx_rendering_defaults and superglue_template for cleaner directories.

class PostsController < ApplicationController
  before_action :use_jsx_rendering_defaults
  superglue_template "application/superglue" #defaults to application/superglue
end

Warning

The file, partial, body, plain, html, inline will not work with render when using before_action :use_jsx_rendering_defaults callback. Make use of :only and :except to narrow down its usage.

Which will allow you to deduplicate the files:

app/views
  application/
    superglue.html.erb
  posts/
    index.jsx
    index.json.props
  users/
    index.jsx
    index.json.props

and omit props files for cases when there is no content.

app/views
  application/
    superglue.html.erb
  about/
    index.jsx

redirect_back_with_props_at

A helper to help retain the props_at parameter as part of the redirect location. This helper has the same method signature as Rails own redirect_back.

def create
  redirect_back_with_props_at fallback_url: '/'
end

Setting the content location

You can override the URL Superglue uses to display on the address bar and store your response directly from the server using content-location. This is optional. For example:

def create
  @post = Post.new(post_params)

  if @post.save
    redirect_to @post, notice: 'Post was successfully created.'
  else
    response.set_header("content-location", new_post_path)
    render :new
  end
end
