-
-## Quickstart
-
-### Before you begin
-
-1.  [Select or create a Cloud Platform project][projects].
-1.  [Enable the Google Cloud Datastore API][enable_api].
-1.  [Set up authentication with a service account][auth] so you can access the
-    API from your local workstation.
-
-### Installing the client library
-
-```bash
-npm install @google-cloud/datastore
-```
-
-
-### Using the client library
-
-```javascript
-// Imports the Google Cloud client library
-const {Datastore} = require('@google-cloud/datastore');
-
-// Creates a client
-const datastore = new Datastore();
-
-async function quickstart() {
-  // The kind for the new entity
-  const kind = 'Task';
-
-  // The name/ID for the new entity
-  const name = 'sampletask1';
-
-  // The Cloud Datastore key for the new entity
-  const taskKey = datastore.key([kind, name]);
-
-  // Prepares the new entity
-  const task = {
-    key: taskKey,
-    data: {
-      description: 'Buy milk',
-    },
-  };
-
-  // Saves the entity
-  await datastore.save(task);
-  console.log(`Saved ${task.key.name}: ${task.data.description}`);
-}
-quickstart();
-
-```
-### Troubleshooting
-#### Emulator returning `DEADLINE_EXCEEDED`, `java.lang.OutOfMemoryError`
-*Reference Issue: [#95](https://github.com/googleapis/nodejs-datastore/issues/95)*
-
-When using the emulator, you may experience errors such as "DEADLINE_EXCEEDED" within your application, corresponding to an error in the emulator: "java.lang.OutOfMemoryError". These errors are unique to the emulator environment and will not persist in production.
-
-A workaround is available, provided by [@ohmpatel1997](https://github.com/ohmpatel1997) [here](https://github.com/googleapis/nodejs-datastore/issues/95#issuecomment-554387312).
-

-
-## Supported Node.js Versions
-
-Our client libraries follow the [Node.js release schedule](https://nodejs.org/en/about/releases/).
-Libraries are compatible with all current _active_ and _maintenance_ versions of
-Node.js.
-If you are using an end-of-life version of Node.js, we recommend that you update
-as soon as possible to an actively supported LTS version.
-
-Google's client libraries support legacy versions of Node.js runtimes on a
-best-efforts basis with the following warnings:
-
-* Legacy versions are not tested in continuous integration.
-* Some security patches and features cannot be backported.
-* Dependencies cannot be kept up-to-date.
-
-Client libraries targeting some end-of-life versions of Node.js are available, and
-can be installed through npm [dist-tags](https://docs.npmjs.com/cli/dist-tag).
-The dist-tags follow the naming convention `legacy-(version)`.
-For example, `npm install @google-cloud/datastore@legacy-8` installs client libraries
-for versions compatible with Node.js 8.
-
-## Versioning
-
-This library follows [Semantic Versioning](http://semver.org/).
-
-
-
-This library is considered to be **stable**. The code surface will not change in backwards-incompatible ways
-unless absolutely necessary (e.g. because of critical security issues) or with
-an extensive deprecation period. Issues and requests against **stable** libraries
-are addressed with the highest priority.

-Please note that this `README.md`, the `samples/README.md`,
-and a variety of configuration files in this repository (including `.nycrc` and `tsconfig.json`)

-/**
- * Idiomatic class for interacting with Cloud Datastore. Uses the lower-level
- * {@link DatastoreClient} class under the hood.
- *
- * In addition to the constructor options shown here, the {@link Datastore}
- * class constructor accepts the same options accepted by
- * {@link DatastoreClient}.
- *
- * <h4>The Datastore Emulator</h4>
- *
- * Make sure you have the <a href="https://cloud.google.com/sdk/downloads">
- * gcloud SDK installed</a>, then run:
- *
- * <pre>
- *   $ gcloud beta emulators datastore start --no-legacy
- * </pre>
- *
- * You will see the following printed:
- *
- * <pre>
- *   [datastore] API endpoint: http://localhost:8005
- *   [datastore] If you are using a library that supports the
- *               DATASTORE_EMULATOR_HOST environment variable, run:
- *   [datastore]
- *   [datastore]   export DATASTORE_EMULATOR_HOST=localhost:8005
- *   [datastore]
- *   [datastore] Dev App Server is now running.
- * </pre>
- *
- * Set that environment variable and your localhost Datastore will
- * automatically be used. You can also pass this address in manually with
- * `apiEndpoint`.
- *
- * Additionally, `DATASTORE_PROJECT_ID` is recognized. If you have this set,
- * you don't need to provide a `projectId`.
- *
- *
- * See {@link https://cloud.google.com/datastore/docs/concepts/overview| Cloud Datastore Concepts Overview}
- *
- * @param {object} [options] Configuration options.
- * @param {string} [options.apiEndpoint] Override the default API endpoint used
- *     to reach Datastore. This is useful for connecting to your local Datastore
- *     server (usually "http://localhost:8080").
- * @param {string} [options.namespace] Namespace to isolate transactions to.
- *
- * @example Import the client library
- * ```
- * const {Datastore} = require('@google-cloud/datastore');
- *
- * ```
- * @example Create a client that uses <a href="https://cloud.google.com/docs/authentication/production#providing_credentials_to_your_application">Application Default Credentials (ADC)</a>:
- * ```
- * const datastore = new Datastore();
- *
- * ```
- * @example Create a client with <a href="https://cloud.google.com/docs/authentication/production#obtaining_and_providing_service_account_credentials_manually">explicit credentials</a>:
- * ```
- * const datastore = new Datastore({
- *   projectId: 'your-project-id',
- *   keyFilename: '/path/to/keyfile.json'
- * });
- *
- * ```
- * @example Retrieving Records
- * ```
- * const {Datastore} = require('@google-cloud/datastore');
- * const datastore = new Datastore();
- *
- * // Records, called "entities" in Datastore, are retrieved by using a key. The
- * // key is more than a numeric identifier, it is a complex data structure that
- * // can be used to model relationships. The simplest key has a string `kind`
- * // value, and either a numeric `id` value, or a string `name` value.
- * //
- * // A single record can be retrieved with {@link Datastore#key} and
- * // {@link Datastore#get}.
- * //-
- * const key = datastore.key(['Company', 'Google']);
- *
- * datastore.get(key, function(err, entity) {
- *   // entity = The record.
- *   // entity[datastore.KEY] = The key for this entity.
- * });
- *
- * //-
- * // <h3>Querying Records</h3>
- * //
- * // Create a query with {@link Datastore#createQuery}.
- * //-
- * const query = datastore.createQuery('Company');
- *
- * //-
- * // Multiple records can be found that match criteria with
- * // {@link Query#filter}.
- * //-
- * query.filter('location', 'CA');
- *
- * //-
- * // Records can also be ordered with {@link Query#order}.
- * //-
- * query.order('name');
- *
- * //-
- * // The number of records returned can be specified with
- * // {@link Query#limit}.
- * //-
- * query.limit(5);
- *
- * //-
- * // Records' key structures can also be queried with
- * // {@link Query#hasAncestor}.
- * //-
- * const ancestorKey = datastore.key(['ParentCompany', 'Alphabet']);
- *
- * query.hasAncestor(ancestorKey);
- *
- * //-
- * // Run the query with {@link Datastore#runQuery}.
- * //-
- * datastore.runQuery(query, (err, entities) => {
- *   // entities = An array of records.
- *
- *   // Access the Key object for an entity.
- *   const firstEntityKey = entities[0][datastore.KEY];
- * });
- *
- * ```
- * @example Paginating Records
- * ```
- * // Imagine building a website that allows a user to sift through hundreds of
- * // their contacts. You'll likely want to only display a subset of these at
- * // once, so you set a limit.
- * //-
- * const express = require('express');
- * const app = express();
- *
- * const NUM_RESULTS_PER_PAGE = 15;
- *
- * app.get('/contacts', (req, res) => {
- *   const query = datastore.createQuery('Contacts')
- *     .limit(NUM_RESULTS_PER_PAGE);
- *
- *   if (req.query.nextPageCursor) {
- *     query.start(req.query.nextPageCursor);
- *   }
- *
- *   datastore.runQuery(query, (err, entities, info) => {
- *     if (err) {
- *       // Error handling omitted.
- *       return;
- *     }
- *
- *     // Respond to the front end with the contacts and the cursoring token
- *     // from the query we just ran.
- *     const frontEndResponse = {
- *       contacts: entities
- *     };
- *
- *     // Check if  more results may exist.
- *     if (info.moreResults !== datastore.NO_MORE_RESULTS) {
- *       frontEndResponse.nextPageCursor = info.endCursor;
- *     }
- *
- *     res.render('contacts', frontEndResponse);
- *   });
- * });
- *
- * ```
- * @example Creating Records
- * ```
- * // New entities can be created and persisted with {@link Datastore#save}.
- * // The entitiy must have a key to be saved. If you don't specify an
- * // identifier for the key, one is generated for you.
- * //
- * // We will create a key with a `name` identifier, "Google".
- * //-
- * const key = datastore.key(['Company', 'Google']);
- *
- * const data = {
- *   name: 'Google',
- *   location: 'CA'
- * };
- *
- * datastore.save({
- *   key: key,
- *   data: data
- * }, (err) => {
- *   if (!err) {
- *     // Record saved successfully.
- *   }
- * });
- *
- * //-
- * // We can verify the data was saved by using {@link Datastore#get}.
- * //-
- * datastore.get(key, (err, entity) => {
- *   // entity = {
- *   //   name: 'Google',
- *   //   location: 'CA'
- *   // }
- * });
- *
- * //-
- * // If we want to update this record, we can modify the data object and re-
- * // save it.
- * //-
- * data.symbol = 'GOOG';
- *
- * datastore.save({
- *   key: key, // defined above (datastore.key(['Company', 'Google']))
- *   data: data
- * }, (err, entity) => {
- *   if (!err) {
- *     // Record updated successfully.
- *   }
- * });
- *
- * ```
- * @example Deleting Records
- * ```
- * // Entities can be removed from Datastore by passing the entity's key object
- * // to {@link Datastore#delete}.
- * //-
- * const key = datastore.key(['Company', 'Google']);
- *
- * datastore.delete(key, (err) => {
- *   if (!err) {
- *     // Record deleted successfully.
- *   }
- * });
- *
- * ```
- * @example Transactions
- * ```
- * // Complex logic can be wrapped in a transaction with
- * // {@link Datastore#transaction}. All queries and updates run within
- * // the transaction will be applied when the `done` function is called.
- * //-
- * const transaction = datastore.transaction();
- *
- * transaction.run((err) => {
- *   if (err) {
- *     // Error handling omitted.
- *   }
- *
- *   const key = datastore.key(['Company', 'Google']);
- *
- *   transaction.get(key, (err, entity) => {
- *     if (err) {
- *       // Error handling omitted.
- *     }
- *
- *     entity.symbol = 'GOOG';
- *
- *     transaction.save(entity);
- *
- *     transaction.commit((err) => {
- *       if (!err) {
- *         // Transaction committed successfully.
- *       }
- *     });
- *   });
- * });
- *
- * ```
- * @example Queries with Ancestors
- * ```
- * const {Datastore} = require('@google-cloud/datastore');
- * const datastore = new Datastore();
- *
- * const customerId1 = 2993844;
- * const customerId2 = 4993882;

+ * Idiomatic class for interacting with Cloud Datastore. Uses the lower-level
+ * {@link DatastoreClient} class under the hood.
+ *
+ * In addition to the constructor options shown here, the {@link Datastore}
+ * class constructor accepts the same options accepted by
+ * {@link DatastoreClient}.
+ *
+ * <h4>The Datastore Emulator</h4>
+ *
+ * Make sure you have the <a href="https://cloud.google.com/sdk/downloads">
+ * gcloud SDK installed</a>, then run:
+ *
+ * <pre>
+ *   $ gcloud beta emulators datastore start --no-legacy
+ * </pre>
+ *
+ * You will see the following printed:
+ *
+ * <pre>
+ *   [datastore] API endpoint: http://localhost:8005
+ *   [datastore] If you are using a library that supports the
+ *               DATASTORE_EMULATOR_HOST environment variable, run:
+ *   [datastore]
+ *   [datastore]   export DATASTORE_EMULATOR_HOST=localhost:8005
+ *   [datastore]
+ *   [datastore] Dev App Server is now running.
+ * </pre>
+ *
+ * Set that environment variable and your localhost Datastore will
+ * automatically be used. You can also pass this address in manually with
+ * `apiEndpoint`.
+ *
+ * Additionally, `DATASTORE_PROJECT_ID` is recognized. If you have this set,
+ * you don't need to provide a `projectId`.
+ *
+ *
+ * See {@link https://cloud.google.com/datastore/docs/concepts/overview| Cloud Datastore Concepts Overview}
+ *
+ * @param {object} [options] Configuration options.
+ * @param {string} [options.apiEndpoint] Override the default API endpoint used
+ *     to reach Datastore. This is useful for connecting to your local Datastore
+ *     server (usually "http://localhost:8080").
+ * @param {string} [options.namespace] Namespace to isolate transactions to.
+ *
+ * @example Import the client library
+ * ```
+ * const {Datastore} = require('@google-cloud/datastore');
+ *
+ * ```
+ * @example Create a client that uses <a href="https://cloud.google.com/docs/authentication/production#providing_credentials_to_your_application">Application Default Credentials (ADC)</a>:
+ * ```
+ * const datastore = new Datastore();
+ *
+ * ```

+ *
+ * // Records, called "entities" in Datastore, are retrieved by using a key. The
+ * // key is more than a numeric identifier, it is a complex data structure that
+ * // can be used to model relationships. The simplest key has a string `kind`
+ * // value, and either a numeric `id` value, or a string `name` value.
+ * //
+ * // A single record can be retrieved with {@link Datastore#key} and
+ * // {@link Datastore#get}.
+ * //-
+ * const key = datastore.key(['Company', 'Google']);
+ *
+ * datastore.get(key, function(err, entity) {
+ *   // entity = The record.
+ *   // entity[datastore.KEY] = The key for this entity.
+ * });
+ *
+ * //-
+ * // <h3>Querying Records</h3>
+ * //
+ * // Create a query with {@link Datastore#createQuery}.
+ * //-
+ * const query = datastore.createQuery('Company');
+ *
+ * //-
+ * // Multiple records can be found that match criteria with
+ * // {@link Query#filter}.
+ * //-
+ * query.filter('location', 'CA');
+ *
+ * //-
+ * // Records can also be ordered with {@link Query#order}.
+ * //-
+ * query.order('name');
+ *
+ * //-
+ * // The number of records returned can be specified with
+ * // {@link Query#limit}.
+ * //-
+ * query.limit(5);
+ *
+ * //-
+ * // Records' key structures can also be queried with
+ * // {@link Query#hasAncestor}.
+ * //-
+ * const ancestorKey = datastore.key(['ParentCompany', 'Alphabet']);
+ *
+ * query.hasAncestor(ancestorKey);
+ *
+ * //-
+ * // Run the query with {@link Datastore#runQuery}.
+ * //-
+ * datastore.runQuery(query, (err, entities) => {
+ *   // entities = An array of records.
+ *
+ *   // Access the Key object for an entity.
+ *   const firstEntityKey = entities[0][datastore.KEY];
+ * });
+ *
+ * ```
+ * @example Paginating Records
+ * ```
+ * // Imagine building a website that allows a user to sift through hundreds of
+ * // their contacts. You'll likely want to only display a subset of these at
+ * // once, so you set a limit.
+ * //-
+ * const express = require('express');

+ *
+ * ```
+ * @example Creating Records
+ * ```
+ * // New entities can be created and persisted with {@link Datastore#save}.
+ * // The entitiy must have a key to be saved. If you don't specify an
+ * // identifier for the key, one is generated for you.

+ * ```
+ * @example Deleting Records
+ * ```

+ * });
+ *
+ * ```
+ * @example Transactions
+ * ```
+ * // Complex logic can be wrapped in a transaction with

+* [License](#license)
+
+## Quickstart
+
+### Before you begin
+
+1.  [Select or create a Cloud Platform project][projects].
+1.  [Enable the Google Cloud Datastore API][enable_api].
+1.  [Set up authentication with a service account][auth] so you can access the
+    API from your local workstation.
+
+### Installing the client library
+
+```bash
+npm install @google-cloud/datastore
+```
+
+
+### Using the client library
+
+```javascript
+// Imports the Google Cloud client library
+const {Datastore} = require('@google-cloud/datastore');
+
+// Creates a client
+const datastore = new Datastore();
+
+async function quickstart() {
+  // The kind for the new entity
+  const kind = 'Task';
+
+  // The name/ID for the new entity
+  const name = 'sampletask1';
+
+  // The Cloud Datastore key for the new entity
+  const taskKey = datastore.key([kind, name]);
+
+  // Prepares the new entity
+  const task = {
+    key: taskKey,
+    data: {
+      description: 'Buy milk',
+    },
+  };
+
+  // Saves the entity
+  await datastore.save(task);
+  console.log(`Saved ${task.key.name}: ${task.data.description}`);
+}
+quickstart();
+
+```
+### Troubleshooting
+#### Emulator returning `DEADLINE_EXCEEDED`, `java.lang.OutOfMemoryError`
+*Reference Issue: [#95](https://github.com/googleapis/nodejs-datastore/issues/95)*
+
+When using the emulator, you may experience errors such as "DEADLINE_EXCEEDED" within your application, corresponding to an error in the emulator: "java.lang.OutOfMemoryError". These errors are unique to the emulator environment and will not persist in production.
+
+A workaround is available, provided by [@ohmpatel1997](https://github.com/ohmpatel1997) [here](https://github.com/googleapis/nodejs-datastore/issues/95#issuecomment-554387312).
+
+
+## Samples
+
+Samples are in the [`samples/`](https://github.com/googleapis/nodejs-datastore/tree/main/samples) directory. Each sample's `README.md` has instructions for running its sample.

+
+## Supported Node.js Versions
+
+Our client libraries follow the [Node.js release schedule](https://nodejs.org/en/about/releases/).
+Libraries are compatible with all current _active_ and _maintenance_ versions of
+Node.js.
+If you are using an end-of-life version of Node.js, we recommend that you update
+as soon as possible to an actively supported LTS version.
+
+Google's client libraries support legacy versions of Node.js runtimes on a
+best-efforts basis with the following warnings:
+
+* Legacy versions are not tested in continuous integration.
+* Some security patches and features cannot be backported.
+* Dependencies cannot be kept up-to-date.
+
+Client libraries targeting some end-of-life versions of Node.js are available, and
+can be installed through npm [dist-tags](https://docs.npmjs.com/cli/dist-tag).
+The dist-tags follow the naming convention `legacy-(version)`.
+For example, `npm install @google-cloud/datastore@legacy-8` installs client libraries
+for versions compatible with Node.js 8.
+
+## Versioning
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+
+
+This library is considered to be **stable**. The code surface will not change in backwards-incompatible ways
+unless absolutely necessary (e.g. because of critical security issues) or with
+an extensive deprecation period. Issues and requests against **stable** libraries
+are addressed with the highest priority.
+
+
