You should instead load your `.proto` files using `@grpc/proto-loader` and load the resulting package definition objects into `@grpc/grpc-js` using `grpc.loadPackageDefinition`. +- If you are currently loading packages generated by `grpc-tools`, you should instead generate your files using the `generate_package_definition` option in `grpc-tools`, then load the object exported by the generated file into `@grpc/grpc-js` using `grpc.loadPackageDefinition`. +- If you have a server and you are using `Server#bind` to bind ports, you will need to use `Server#bindAsync` instead. +- If you are using any channel options supported in `grpc` but not supported in `@grpc/grpc-js`, you may need to adjust your code to handle the different behavior. Refer to [the list of supported options](#supported-channel-options) below. +- Refer to the [detailed package comparison](https://github.com/grpc/grpc-node/blob/master/PACKAGE-COMPARISON.md) for more details on the differences between `grpc` and `@grpc/grpc-js`. + +## Supported Channel Options +Many channel arguments supported in `grpc` are not supported in `@grpc/grpc-js`.

These methods are internal and should not be considered part of the public API. +- The class `Call` is only exposed due to limitations of TypeScript. It should not be considered part of the public API. +- In general, any API that is exposed by this library but is not exposed by the `grpc` library is likely an error and should not be considered part of the public API. +- The `grpc.experimental` namespace contains APIs that have not stabilized. Any API in that namespace may break in any minor version update. diff --git a/frontend-old/node_modules/@grpc/grpc-js/build/src/admin.d.ts b/frontend-old/node_modules/@grpc/grpc-js/build/src/admin.d.ts new file mode 100644 index 0000000..92b9bba --- /dev/null +++ b/frontend-old/node_modules/@grpc/grpc-js/build/src/admin.d.ts @@ -0,0 +1,11 @@ +import { ServiceDefinition } from './make-client'; +import { Server, UntypedServiceImplementation } from './server'; +interface GetServiceDefinition { + (): ServiceDefinition; +} +interface GetHandlers { + (): UntypedServiceImplementation; +} +export declare function registerAdminService(getServiceDefinition: GetServiceDefinition, getHandlers: GetHandlers): void; +export declare function addAdminServicesToServer(server: Server): void; +export {}; diff --git a/frontend-old/node_modules/@grpc/grpc-js/build/src/admin.js b/frontend-old/node_modules/@grpc/grpc-js/build/src/admin.js new file mode 100644 index 0000000..9fd8e64 --- /dev/null +++ b/frontend-old/node_modules/@grpc/grpc-js/build/src/admin.js @@ -0,0 +1,31 @@ +"use strict"; +/* + * Copyright 2021 gRPC authors. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + * + */ +Object.defineProperty(exports, "__esModule", { value: true }); +exports.addAdminServicesToServer = exports.registerAdminService = void 0; +const registeredAdminServices = []; +function registerAdminService(getServiceDefinition, getHandlers) { + registeredAdminServices.push({ getServiceDefinition, getHandlers }); +} +exports.registerAdminService = registerAdminService; +function addAdminServicesToServer(server) { + for (const { getServiceDefinition, getHandlers } of registeredAdminServices) { + server.addService(getServiceDefinition(), getHandlers()); + } +} +exports.addAdminServicesToServer = addAdminServicesToServer; +//# sourceMappingURL=admin.js.map
