WebSockets Operations
You can execute CRUD operations over Directus' WebSockets interface.
This guide assumes you already know how to establish, authenticate, and send messages over a WebSocket connection.
GraphQL
The GraphQL Subscriptions specification does not support CRUD operations. This guide is only suitable for WebSockets connections not using GraphQL.
Read Items
{
"type": "items",
"action": "read",
"collection": "your_collection_name",
"id": "single_item_id"
}
{
"type": "items",
"action": "read",
"collection": "your_collection_name",
"id": "single_item_id"
}
In return, you will receive a message with the specified item:
{
"type": "items",
"data": {
// ...
}
}
{
"type": "items",
"data": {
// ...
}
}
Read Multiple Items
Instead of using an id
property, you can use an ids
property with an array of item IDs you'd like to return, or omit it to return all items in the specified collection. When returning multiple items, data
will be an array of objects.
Create Items
{
"type": "items",
"action": "create",
"collection": "your_collection_name",
"data": {
// ...
}
}
{
"type": "items",
"action": "create",
"collection": "your_collection_name",
"data": {
// ...
}
}
In return, you will receive a message with the newly-created item:
{
"type": "items",
"data": {
// ...
}
}
{
"type": "items",
"data": {
// ...
}
}
Create Multiple Items
Instead of using an object as the value of data
, you can provide an array of objects to create multiple items at once. The returned payload will also contain an array.
Update Items
{
"type": "items",
"action": "update",
"collection": "your_collection_name",
"id": "single_item_id",
"data": {
// ...
}
}
{
"type": "items",
"action": "update",
"collection": "your_collection_name",
"id": "single_item_id",
"data": {
// ...
}
}
Regardless of how many items are updated, the data
in the returned object will always be an array.
{
"type": "subscription",
"event": "update",
"data": [
// ...
]
}
{
"type": "subscription",
"event": "update",
"data": [
// ...
]
}
Update Multiple Items
Instead of using an id
property, you can use an ids
property with an array of item IDs to update multiple items at a time.
Delete Items
{
"type": "items",
"action": "delete",
"collection": "your_collection_name",
"id": "single_item_id"
}
{
"type": "items",
"action": "delete",
"collection": "your_collection_name",
"id": "single_item_id"
}
Regardless of how many items are updated, the data
in the returned data will always be an array containing all IDs from deleted items:
{
"type": "items",
"event": "delete",
"data": ["single_item_id", "single_item_id_2"]
}
{
"type": "items",
"event": "delete",
"data": ["single_item_id", "single_item_id_2"]
}
Delete Multiple Items
Instead of using an id
property, you can use an ids
property with an array of item IDs to delete multiple items at a time.
Instead of using an id
property, you can also use delete items based on a provided query
property. To delete all items, provide an empty query object.
Operations With Queries
For non-delete operations, all fields that the user has access to are returned by default. You can add an optional query
property along with any of the global query parameters to change the returned data.
When running a delete operation, the items matching the query
property will be deleted.
Use UIDs To Better Understand Responses
All messages sent over WebSockets can optionally include a uid
property with an arbitrary string and will be echoed in the response. This allows you to identify which request a given response is related to. For example:
{
"type": "items",
"action": "read",
"collection": "your_collection_name",
"query": {
"sort": "date_created"
},
"uid": "sorted_latest_first"
}
{
"type": "items",
"action": "read",
"collection": "your_collection_name",
"query": {
"sort": "date_created"
},
"uid": "sorted_latest_first"
}
The response will include the same uid
:
{
"type": "items",
"data": {
// ...
},
"uid": "sorted_latest_first"
}
{
"type": "items",
"data": {
// ...
},
"uid": "sorted_latest_first"
}
