@dynatrace-sdk/client-state

Overview

Provides key-value storage for apps so that app developers can persist and get small chunks of state in the context of their app.

States can either be stored in the context of an app (= app states) or in the context of an app and user (= user app states).

• States stored per app can be read by every user of the app.
• States stored per app and user can only be read and updated by the user who originally set that state. Please visit the Dynatrace Developer to learn more about app states and user app states.

Installation

npm install @dynatrace-sdk/client-state

stateClient

import { stateClient } from '@dynatrace-sdk/client-state';

deleteAppState

Deletes app state

Required scope: state:app-states:delete

Parameters

| Name | Type | Description | | --- | --- | --- | |config.key*required|string|Specify the key of the state |

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.deleteAppState({
  key: "some-key",
});

deleteAppStates

Delete all app states

Required scope: state:app-states:delete

Deletes all app states for an app to reset the app into a clean state.

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.deleteAppStates();

deleteUserAppState

Delete user app state

Required scope: state:user-app-states:delete

Parameters

| Name | Type | Description | | --- | --- | --- | |config.key*required|string|Specify the key of the state |

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.deleteUserAppState({
  key: "some-key",
});

deleteUserAppStates

Delete all user app states

Required scope: state:user-app-states:delete

Deletes all user app states for the calling user and app.

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.deleteUserAppStates();

getAppState

Gets app state

Required scope: state:app-states:read

Parameters

| Name | Type | Description | | --- | --- | --- | |config.key*required|string|Specify the key of the state |

Returns

The app state

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.getAppState({
  key: "some-key",
});

getAppStates

List app states

Required scope: state:app-states:read

Lists app states. By default, only provides property key per state. Use add-fields parameter to include more fields and the filter parameter to narrow down the returned states.

Parameters

| Name | Type | Description | | --- | --- | --- | |config.addFields|string|Provide a comma separated list of additional properties to be included in the response. | |config.filter|string|The filter parameter for filtering the set of returned resources If this parameter is omitted, no filtering is applied and all states will be returned. Filtering by string type parameters key, modificationInfo.lastModifiedBy when using one of the operators contains, starts-with and ends-with is case insensitive. When using the operators =and !=, filtering is case sensitive. The following fields are legal filtering parameters - any other field names will result in a HTTP 400 response: key, supported operators: =, !=, contains, starts-with, ends-with: modificationInfo.lastModifiedTime, supported operators: =, !=, <, <=, >, >= modificationInfo.lastModifiedBy, supported operators: =, !=, contains, starts-with, ends-with validUntilTime, supported operators: =, !=, <, <=, >, >= The following constraints apply: Field names are case-sensitive. Conditions can be connected via operators and and or. A single condition can be negated by not. Strings must be enclosed in single quotes. e.g. key contains 'my-string' Single quotes within a string must be escaped with a backslash: e.g. key starts-with 'it\'s a string' Maximum nesting depth (via brackets) is 2. Maximum length is 256 characters. Examples: key starts-with 'game-' modificationInfo.lastModifiedTime >= '2022-07-01T00:10:05.000Z' and not (key contains 'new') |

Returns

The list of app states

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.getAppStates();

getUserAppState

Required scope: state:user-app-states:read

Parameters

| Name | Type | Description | | --- | --- | --- | |config.key*required|string|Specify the key of the state |

Returns

import { stateClient } from "@dynatrace-sdk/client-state";

const data = await stateClient.getUserAppState({
  key: "some-key",
});

getUserAppStates

List user app states

Required scope: state:user-app-states:read

Lists user app states. By default, only provides property key per state. Use add-fields parameter to include more fields and the filter parameter to narrow down the returned states
