taro开发小程序，想用apollo-client 的 WebSocketLink，一直报module "npm/ws/index.js" is not defined
-
Object.defineProperty(exports, "__esModule", { value: true });
var WebSocket = require("../../ws/index.js"); // 加载不到websocket
var message_types_1 = require("./message-types.js");
var protocol_1 = require("./protocol.js");
var is_object_1 = require("./utils/is-object.js");
var graphql_1 = require("../../graphql/index.js");
var empty_iterable_1 = require("./utils/empty-iterable.js");
var iterall_1 = require("../../iterall/index.js");
var is_subscriptions_1 = require("./utils/is-subscriptions.js");
var parse_legacy_protocol_1 = require("./legacy/parse-legacy-protocol.js");
var isWebSocketServer = function (socket) {
return socket.on;
};下面是项目代码
....
const wsLink = new WebSocketLink({
uri:ws://localhost:5000/,
options: {
reconnect: false,
// reconnect: true
connectionParams: async () => {
const { accessToken: token } = await getItem(keys.auth);
return { token };
}
}
});....
const link = ApolloLink.from([
onError(({ graphQLErrors, networkError }) => {
if (graphQLErrors) {
graphQLErrors.map(({ message, locations, path }) =>
console.log(
[GraphQL error]: Message: ${message}, Location: ${locations}, Path: ${path}
)
);
}
if (networkError)
console.error([Network error]: ${networkError}, networkError.stack);
}),
authMiddleware,
// 小程序不支持websocket 需要用Taro.connectSocket
ApolloLink.split(
({ query }) => {
const { kind, operation } = getMainDefinition(query);
return kind === "OperationDefinition" && operation === "subscription";
},
wsLink,
httpLink
)
]);

@woshiji_111 在 taro开发小程序，想用apollo-client 的 WebSocketLink，一直报module "npm/ws/index.js" is not defined 中说：
const wsLink = new WebSocketLink({
uri: ws://localhost:5000/,
options: {
reconnect: false,
// reconnect: true
connectionParams: async () => {
const { accessToken: token } = await getItem(keys.auth);
return { token };
}
}
});
....
const link = ApolloLink.from([
onError(({ graphQLErrors, networkError }) => {
if (graphQLErrors) {
graphQLErrors.map(({ message, locations, path }) =>
console.log(
[GraphQL error]: Message: ${message}, Location: ${locations}, Path: ${path}
)
);
}
if (networkError)是因为微信小程序环境的node模块缺少 ws ? https://github.com/websockets/ws

我写了个可以用在微信里面的subscription client
