Compiled JavaScript code (such as all files under a block's build/
folder) is added to the repo, but only as compiled for production, i.e. after running npm run build
.
Code compiled for development, i.e. after running npm start
, cannot be commited/pushed to the repo.
GraphQL API is extensible, and ships with the following modules (organized by category):
Module | Description |
---|---|
Endpoint | |
Single Endpoint | Expose the single GraphQL endpoint under /graphql/ |
Persisted Queries | Expose predefined responses through a custom URL, akin to using GraphQL queries to publish REST endpoints |
Custom Endpoints | Expose different subsets of the schema for different targets, such as users (clients, employees, etc), applications (website, mobile app, etc), context (weekday, weekend, etc), and others |
API Hierarchy | Create a hierarchy of API endpoints extending from other endpoints, and inheriting their properties |
Schema Configuration | |
Schema Configuration | Customize the schema accessible to different Custom Endpoints and Persisted Queries, by applying a custom configuration (involving namespacing, access control, cache control, and others) to the grand schema |
Schema Namespacing | Automatically namespace types with a vendor/project name, to avoid naming collisions |
Nested Mutations | Execute mutations from any type in the schema, not only from the root |
Public/Private Schema | Enable to communicate the existence of some field from the schema to certain users only (private mode) or to everyone (public mode). If disabled, fields are always available to everyone (public mode) |
User Interface | |
Excerpt as Description | Provide a description of the different entities (Custom Endpoints, Persisted Queries, and others) through their excerpt |
Clients | |
GraphiQL for Single Endpoint | Make a public GraphiQL client available under /graphiql/ , to execute queries against the single endpoint. It requires pretty permalinks enabled |
Interactive Schema for Single Endpoint | Make a public Interactive Schema client available under /schema/ , to visualize the schema accessible through the single endpoint. It requires pretty permalinks enabled |
GraphiQL for Custom Endpoints | Enable custom endpoints to be attached their own GraphiQL client, to execute queries against them |
Interactive Schema for Custom Endpoints | Enable custom endpoints to be attached their own Interactive schema client, to visualize the custom schema subset |
GraphiQL Explorer | Add the Explorer widget to the GraphiQL client, to simplify coding the query (by point-and-clicking on the fields) |
Schema Type | |
Expose Sensitive Data in the Schema | Expose “sensitive” data elements in the GraphQL schema (such as field Root.roles , field arg Root.posts(status:) , and others), which provide access to potentially private user data |
Self Fields | Expose "self" fields in the GraphQL schema (such as Post.self and User.self ), which can help give a particular shape to the GraphQL response |
Schema Custom Posts | Query Custom Post Types |
Schema Posts | Query posts, through type Post added to the schema |
Schema Pages | Query pages, through type Page added to the schema |
Schema Users | Query users, through type User added to the schema |
Schema User Roles | Query user roles, through type UserRole added to the schema |
Schema User Avatars | Query user avatars, through type UserAvatar added to the schema |
Schema Comments | Query comments, through type Comment added to the schema |
Schema Tags | Base functionality for all tags |
Schema Post Tags | Query post tags, through type PostTag added to the schema |
Schema Categories | Base functionality for all categories |
Schema Post Categories | Query post categories, through type PostCategory added to the schema |
Schema Media | Query media elements, through type Media added to the schema |

Schema Settings | Fetch settings from the site |

Schema Post Mutations | Execute mutations on podyd |
Schema Custom Post Media Mutations | Execute mutations concerning media items on custom posts |
Schema Post Media Mutations | Execute mutations concerning media items on posts |
Schema Post Tag Mutations | Add tags to posts |
