Use this skill alongside the adonisjs skill when the project uses the AdonisJS Hypermedia starter kit or Edge.js server-side templates. Trigger for .edge files, view.render(), router.on().render(), resources/views, Edge syntax, AdonisJS Edge helpers, request/auth/session/flashMessages/old/route/signedRoute/config/app/asset/i18n, @vite/@viteReactRefresh/@can/@cannot/@flashMessage/@error/@inputError, template state, interpolation, conditionals, @if/@elseif/@else/@unless, loops, @each, layouts, Edge components, component props, $props, slots, provide/inject, $context, partials, @include/@includeIf, stacks, @stack/@pushTo, form components, CSRF form helpers, field/input/select/textarea components, alert/button/link/avatar components, or debugging templates with @dump.

Edge Templates for AdonisJS

This skill covers the Edge.js server-rendered view layer in AdonisJS Hypermedia apps. Use adonisjs alongside it for controllers, routes, middleware, auth, validation, services, and framework architecture.

When to Use

Use this skill for:

• Rendering .edge templates from controllers or route handlers
• Working in resources/views/**
• Applying Edge syntax rules for curly braces, @ tags, comments, and newline swallowing
• Writing interpolation with {{ }}, {{{ }}}, html.safe(), or escaped @{{ }}
• Writing conditional blocks with @if, @elseif, @else, @unless, or short ternaries
• Looping over arrays and objects with @each, indexes, keys, and empty-state fallbacks
• Building layouts, components, slots, partials, and reusable template fragments
• Building components with props, $props, slots, layout components, and provide/inject
• Including partials and pushing template-specific content into stacks
• Passing template state to view.render()
• Using AdonisJS-provided Edge helpers and tags from official packages
• Using Hypermedia starter kit form and UI components
• Debugging template variables, helpers, and rendering problems

Do not use this skill for Inertia page components. Use inertia-vue or inertia-react for those frontend layers.

Rendering Templates

Render templates from controllers with view.render(template, state). The template path is relative to resources/views and omits the .edge extension.

import Post from '#models/post'
import type { HttpContext } from '@adonisjs/core/http'

export default class PostsController {
  async index({ view }: HttpContext) {
    return view.render('pages/posts/index', {
      posts: await Post.all(),
    })
  }
}

For static pages, routes can render a template directly.

import router from '@adonisjs/core/services/router'

router.on('/').render('pages/home')

Template State

Read references/template-state.md when working with data passed to templates, framework-provided values, @let, @assign, globals, or Edge standalone state APIs.

Every property passed as the second argument to view.render() becomes a template variable. Prefer explicit state names over reaching into broad service objects from the template.

@layout()
  @each(post in posts)
    <article>
      <h2>{{ post.title }}</h2>
      <p>{{ post.summary }}</p>
    </article>
  @end
@end

AdonisJS also shares request/auth context and Edge helpers with templates. When a value is unclear, inspect the state during development with @dump(state) or a specific variable with @dump(posts).

Syntax Defaults

Read references/interpolation.md when working with interpolation, multiline JavaScript expressions, stringified output, HTML escaping, or @{{ }} escaping for frontend frameworks. Read references/syntax-specification.md when working with low-level Edge syntax rules, tag placement, auto-closing tags, comments, or ~ newline swallowing. Read references/conditionals.md when working with @if, @elseif, @else, @unless, or ternary expressions in templates. Read references/loops.md when working with @each, indexes, object key/value loops, or @each ... @else fallback content. Read references/components.md when working with component files, component tag names, props, $props, slots, layout components, @inject, or $context. Read references/partials-and-stacks.md when working with @include, @includeIf, @stack, @pushTo, @pushToTop, or push-once stack behavior. Read references/adonisjs-helpers-and-tags.md when working with AdonisJS-provided Edge helpers/tags such as request, route, signedRoute, session, flashMessages, old, auth, asset, @vite, @can, @flashMessage, @error, or @inputError.

Use escaped output by default.

{{ post.title }}

Use unescaped output only for trusted HTML that has already been sanitized or generated by trusted code.

{{{ post.html }}}

Common control flow:

@if(auth.user)
  <p>Welcome back, {{ auth.user.fullName }}</p>
@else
  <p>Please log in</p>
@end

@each(post in posts)
  <h2>{{ post.title }}</h2>
@end

Layouts and Components

The Hypermedia starter kit provides a @layout() component at resources/views/components/layout.edge. It owns the HTML document shell and renders page content through the default slot. Read references/components.md when creating or changing custom components.

@layout()
  <main>
    Page content
  </main>
@end

Create reusable components under resources/views/components. The file name becomes the component tag name.

{{-- resources/views/components/card.edge --}}
<div class="card">
  {{{ await $slots.main() }}}
</div>

@card()
  <h2>Card title</h2>
@end

Use the self-closing @!component() form only for components that do not need slots.

Hypermedia Starter Kit Components

Read references/hypermedia-components.md when working with the starter kit's pre-built components.

Important defaults:

• Each component renders at most one HTML element.
• Unknown props are passed through as HTML attributes.
• @form() injects CSRF protection and supports method spoofing for PUT, PATCH, and DELETE.
• Field controls are composed from @field.root(), @field.label(), control components, and @field.error().
• @link() can generate URLs from named routes with route, routeParams, and routeOptions.

Form Pattern

Prefer route names over hard-coded URLs when the route is named.

@form({ route: 'posts.store', method: 'POST' })
  @field.root({ name: 'title' })
    @!field.label({ text: 'Title' })
    @!input.control({ type: 'text', maxlength: '120' })
    @!field.error()
  @end

  @!button({ text: 'Create post', type: 'submit' })
@end

For update/delete forms, use method spoofing through the component.

@form({ route: 'posts.update', method: 'PUT', routeParams: [post.id] })
  {{-- fields --}}
@end

Review Checklist

• Template files live under resources/views and use .edge.
• Controller state is explicit and named for template usage.
• Request/page-specific data is passed through view.render() rather than Edge standalone renderer APIs.
• Escaped output {{ }} is the default; unescaped output {{{ }}} is justified.
• Multiline interpolation keeps each double-curly delimiter on the same line.
• Edge tags are placed on their own line; use @!tag() with no space for auto-closed components.
• Conditional blocks use @unless only for simple negated conditions; complex branches use clearer state or @if.
• Empty collection states use @each ... @else when a fallback is tied directly to the loop.
• Partials are used for markup fragments; components are preferred when props or slots are needed.
• Components forward unknown HTML attributes with $props.toAttrs() or $props.merge(...).toAttrs() when wrapping native elements.
• Provide/inject is limited to tightly coupled component families, not page-level state.
• Stacks are reserved for content that must render in a layout-owned placeholder, such as page-specific scripts.
• Forms use the starter kit @form() component for CSRF/method spoofing.
• Field inputs stay inside @field.root() so labels and errors remain accessible.
• Route-aware components use route names instead of duplicated URLs when possible.
• AdonisJS helpers/tags are used only when their contributing package and rendering context are available.
• Debug-only @dump() calls are removed before completion.
