Accesses the schemaless NoSQL database to provide fully managed, robust, scalable storage for your application. For detailed description please check documentation.
Install typings for Cloud Datastore API:
npm install @types/gapi.client.datastore-v1beta3 --save-dev
You need to initialize Google API client in your code:
gapi.load('client', () => {
// now we can use gapi.client
// ...
});
Then load api client wrapper:
gapi.client.load(
'https://datastore.googleapis.com/$discovery/rest?version=v1beta3',
() => {
// now we can use:
// gapi.client.datastore
}
);
// Deprecated, use discovery document URL, see https://github.com/google/google-api-javascript-client/blob/master/docs/reference.md#----gapiclientloadname----version----callback--
gapi.client.load('datastore', 'v1beta3', () => {
// now we can use:
// gapi.client.datastore
});
Don't forget to authenticate your client before sending any request to resources:
// declare client_id registered in Google Developers Console
var client_id = '',
scope = [
// See, edit, configure, and delete your Google Cloud data and see the email address for your Google Account.
'https://www.googleapis.com/auth/cloud-platform',
// View and manage your Google Cloud Datastore data
'https://www.googleapis.com/auth/datastore',
],
immediate = true;
// ...
gapi.auth.authorize(
{client_id: client_id, scope: scope, immediate: immediate},
authResult => {
if (authResult && !authResult.error) {
/* handle successful authorization */
} else {
/* handle authorization error */
}
}
);
After that you can use Cloud Datastore API resources:
/*
Allocates IDs for the given keys, which is useful for referencing an entity before it is inserted.
*/
await gapi.client.datastore.projects.allocateIds({projectId: 'projectId'});
/*
Begins a new transaction.
*/
await gapi.client.datastore.projects.beginTransaction({projectId: 'projectId'});
/*
Commits a transaction, optionally creating, deleting or modifying some entities.
*/
await gapi.client.datastore.projects.commit({projectId: 'projectId'});
/*
Looks up entities by key.
*/
await gapi.client.datastore.projects.lookup({projectId: 'projectId'});
/*
Prevents the supplied keys' IDs from being auto-allocated by Cloud Datastore.
*/
await gapi.client.datastore.projects.reserveIds({projectId: 'projectId'});
/*
Rolls back a transaction.
*/
await gapi.client.datastore.projects.rollback({projectId: 'projectId'});
/*
Runs an aggregation query.
*/
await gapi.client.datastore.projects.runAggregationQuery({
projectId: 'projectId',
});
/*
Queries for entities.
*/
await gapi.client.datastore.projects.runQuery({projectId: 'projectId'});
