fetchProxy()

fetchProxy(containerId, path, params?): Promise<Response>

Defined in: js-api/src/dapi.ts:2114

Proxies URL requests to Docker containers via Datagrok server with the same interface as fetch. Returns response from the containers as it is. If an error occurs on the server side returns a response with "application/json" Content-Type and JSON body with field "datagrok-error" that describes the cause. If container status is incorrect for performing requests returns a response with a 400 status code. If something goes wrong in the server workflow, it returns a response with a 500 status code. Any other cases are the result of direct requests to the container itself.

Parameters

Parameter	Type	Description
containerId	string	ID of the DockerContainer to which the http request should be sent.
path	string	URI without scheme and authority component.
params?	RequestInit	parameters of the request.

Returns

Promise<Response>

promise that resolves with Response.

webSocketProxy()

webSocketProxy(containerId, path, timeout?): Promise<WebSocket>

Defined in: js-api/src/dapi.ts:2130

Proxies WebSocket connection to Docker containers via Datagrok server. Returns ready WebSocket that is connected through the server to the Docker container WebSocket endpoint. If container status is incorrect or there is error while establishing WebSocket connection to Docker container, caller will receive an error. After the WebSocket is returned, caller can do anything with it and should take care of reconnection. After the caller closes the connection, server will close proxied Docker WebSocket connection.

Parameters

Parameter	Type	Default value	Description
containerId	string	undefined	ID of the DockerContainer to which the WebSocket connection will be established.
path	string	undefined	URI without scheme and authority component that points to endpoint inside the Docker container
timeout	number	60000	Timeout in ms for initial connection establishment. Set it to higher values if you are using container with on_demand configuration set to true.

Returns

Promise<WebSocket>

---

webSocketProxySync()

webSocketProxySync(containerId, path, timeout?): WebSocket

Defined in: js-api/src/dapi.ts:2184

This is the synchronous version of the function webSocketProxy. Note that the container won't be ready to accept messages immediately after this function returns. If your application logic requires sending a message right away, consider using the asynchronous version.

Parameters

Parameter	Type	Default value	Description
containerId	string	undefined	ID of the DockerContainer to which the WebSocket connection will be established.
path	string	undefined	URI without scheme and authority component that points to endpoint inside the Docker container
timeout	number	60000	Timeout in ms for initial connection establishment. Set it to higher values if you are using container with on_demand configuration set to true.

Returns

WebSocket

with()

protected with(patch): this

Defined in: js-api/src/dapi.ts:344

A copy of this source whose query has [patch] applied. The Dart handle is shared; its state is rebuilt from the query right before every request, so the copies never observe each other.

Parameters

Parameter	Type
patch	Partial<DataSourceQuery>

Returns

this

Inherited from

HttpDataSource.with
