Backpex ships with a Claude Code plugin that gives AI assistants deep knowledge of Backpex conventions, APIs, and patterns. This means Claude can generate correct Backpex code (filters, fields, actions, and LiveResources) without you having to explain the framework from scratch.
Install the Backpex Plugin
The plugin is distributed as a Claude Code marketplace directly from the Backpex repository.
Add the Marketplace
Open Claude Code and run:
/plugin marketplace add naymspace/backpex
This registers the Backpex marketplace so you can browse and install plugins from it.
Install the Plugin
/plugin install backpex@naymspace-backpex
After installation, run /reload-plugins to activate the plugin.
What the Plugin Provides
The Backpex plugin includes skills, specialized knowledge modules that Claude uses automatically when working on Backpex projects.
Create Live Resource
The create-live-resource skill helps scaffold complete LiveResource modules. It covers adapter_config, required callbacks (singular_name/0, plural_name/0, fields/0, layout/1), optional callbacks like can?/3 and filters/0, and router setup with live_resources/3.
Example: "Create a LiveResource for my Product schema with name, price, and category fields"
Create Field
The create-field skill covers all 17 built-in field types and how to create custom fields implementing Backpex.Field. It includes the config schema, required callbacks (render_value/1, render_form/1), common field options, and template assigns.
Example: "Add a color picker field to my ProductLive resource"
Create Filter
The create-filter skill covers all built-in filter types (Boolean, Select, MultiSelect, Range) and custom filters. It includes required callbacks, how to wire filters into filters/0, and options like presets and defaults.
Example: "Add a published filter to PostLive"
Create Item Action
The create-item-action skill helps create custom actions for table rows and the show page. It covers the handle/3 vs link/2 pattern, form fields with confirmation dialogs, and how to modify the default actions (show, edit, delete).
Example: "Add an archive action that soft-deletes selected posts"
Create Resource Action
The create-resource-action skill helps create resource-level actions like exports, imports, or invitations. It covers the required callbacks (title/0, label/0, fields/0, changeset/3, handle/2) and schemaless changeset patterns.
Example: "Create an export action that lets users download posts as CSV"
Upgrade
The upgrade skill assists with Backpex version upgrades. It reads the relevant upgrade guides, identifies breaking changes, and applies migrations systematically.
Example: "Upgrade Backpex from 0.16 to 0.18"
Invoking Skills
All skills are triggered automatically by Claude when it detects relevant work. You can also invoke them directly:
/backpex:create-live-resource
/backpex:create-field
/backpex:create-filter
/backpex:create-item-action
/backpex:create-resource-action
/backpex:upgrade
