This skill provides expert guidance on rendering HTML templates using ECR (Embedded Crystal) in Kemal, strictly following patterns from kemal-by-example.
render "path/to/view.ecr" for simple rendering.render "path/to/view.ecr", "path/to/layout.ecr" for layout support.src/views/index.ecr).HTML.escape(...) (require "html") when outputting with <%= ... %>.# blog/src/routes/posts.cr
get "/posts" do
posts = Post.all
render "src/views/posts/index.ecr", "src/views/layouts/application.ecr"
end
# ecommerce/src/routes/auth.cr
get "/signup" do |env|
current_user = Ecommerce::Auth.current_user(env)
cart_count = if (user = current_user) && (uid = user.id)
CartItem.total_quantity_for_user(uid)
else
0_i64
end
error_message = nil
render "src/views/auth/signup.ecr", "src/views/layouts/application.ecr"
end
# blog/src/routes/posts.cr
get "/posts/:id/edit" do |env|
id = env.params.url["id"]?.try(&.to_i64?)
post = id ? Post.find(id) : nil
if post
render "src/views/posts/edit.ecr", "src/views/layouts/application.ecr"
else
env.response.status = :not_found
"Post not found"
end
end
Typical layout file at src/views/layouts/application.ecr:
<!DOCTYPE html>
<html>
<head>
<title>My App</title>
</head>
<body>
<nav>
<!-- Navigation content -->
</nav>
<main>
<%= content %>
</main>
<footer>
<!-- Footer content -->
</footer>
</body>
</html>
Typical view file at src/views/posts/index.ecr. ECR does not auto-escape output, so any user-provided value rendered with <%= ... %> must go through HTML.escape (stdlib, require "html") to prevent XSS:
<h1>Posts</h1>
<% posts.each do |post| %>
<article>
<h2><%= HTML.escape(post.title) %></h2>
<p><%= HTML.escape(post.body) %></p>
<a href="/posts/<%= post.id %>/edit">Edit</a>
</article>
<% end %>
<a href="/posts/new">New Post</a>
# ecommerce/src/routes/auth.cr
post "/login" do |env|
email = env.params.body["email"]?.try(&.strip) || ""
password = env.params.body["password"]?.try(&.strip) || ""
user = User.authenticate(email, password)
if user
Ecommerce::Auth.sign_in(env, user)
env.redirect "/products"
else
current_user = nil
cart_count = 0_i64
error_message = "Invalid email or password."
env.response.status = :unprocessable_entity
render "src/views/auth/login.ecr", "src/views/layouts/application.ecr"
end
end
<%= content %> in layout files to render the view content.render "path/to/_partial.ecr" for reusable UI components (not shown in examples but standard practice).<%= ... %> for output and <% ... %> for logic/control flow.HTML.escape(...) inside <%= ... %>; only render raw HTML you generated yourself (like the layout's <%= content %>).render.
