-
- ### BREAKING CHANGES
-
- * the Socket#use() method is removed (see [5c73733](https://github.com/socketio/socket.io/commit/5c737339858d59eab4b5ee2dd6feff0e82c4fe5a))
-
- * Socket#join() and Socket#leave() do not accept a callback argument anymore.
-
- Before:
-
- ```js
- socket.join("room1", () => {
- io.to("room1").emit("hello");
- });
- ```
-
- After:
-
- ```js
- socket.join("room1");
- io.to("room1").emit("hello");
- // or await socket.join("room1"); for custom adapters
- ```
-
- * the "connected" map is renamed to "sockets"
- * the Socket#binary() method is removed, as this use case is now covered by the ability to provide your own parser.
- * the 'origins' option is removed
-
- Before:
-
- ```js
- new Server(3000, {
- origins: ["https://example.com"]
- });
- ```
-
- The 'origins' option was used in the allowRequest method, in order to
- determine whether the request should pass or not. And the Engine.IO
- server would implicitly add the necessary Access-Control-Allow-xxx
- headers.
-
- After:
-
- ```js
- new Server(3000, {
- cors: {
- origin: "https://example.com",
- methods: ["GET", "POST"],
- allowedHeaders: ["content-type"]
- }
- });
- ```
-
- The already existing 'allowRequest' option can be used for validation:
-
- ```js
- new Server(3000, {
- allowRequest: (req, callback) => {
- callback(null, req.headers.referer.startsWith("https://example.com"));
- }
- });
- ```
-
- * Socket#rooms is now a Set instead of an object
-
- * Namespace#connected is now a Map instead of an object
-
- * there is no more implicit connection to the default namespace:
-
- ```js
- // client-side
- const socket = io("/admin");
-
- // server-side
- io.on("connect", socket => {
- // not triggered anymore
- })
-
- io.use((socket, next) => {
- // not triggered anymore
- });
-
- io.of("/admin").use((socket, next) => {
- // triggered
- });
- ```
-
- * the Server#set() method was removed
-
- This method was kept for backward-compatibility with pre-1.0 versions.

-
- ### BREAKING CHANGES
-
- * the 'origins' option is removed
-
- Before:
-
- ```js
- new Server(3000, {
- origins: ["https://example.com"]
- });
- ```
-
- The 'origins' option was used in the allowRequest method, in order to
- determine whether the request should pass or not. And the Engine.IO
- server would implicitly add the necessary Access-Control-Allow-xxx
- headers.
-
- After:
-
- ```js
- new Server(3000, {
- cors: {
- origin: "https://example.com",
- methods: ["GET", "POST"],
- allowedHeaders: ["content-type"]
- }
- });
- ```
-
- The already existing 'allowRequest' option can be used for validation:
-
- ```js
- new Server(3000, {
- allowRequest: (req, callback) => {
- callback(null, req.headers.referer.startsWith("https://example.com"));
- }
- });
- ```
-
- * Socket#rooms is now a Set instead of an object
-
- * Namespace#connected is now a Map instead of an object
-
- * there is no more implicit connection to the default namespace:
-
- ```js
- // client-side
- const socket = io("/admin");
-
- // server-side
- io.on("connect", socket => {
- // not triggered anymore
- })
-
- io.use((socket, next) => {
- // not triggered anymore
- });
-
- io.of("/admin").use((socket, next) => {
- // triggered
- });
- ```
-
- * the Server#set() method was removed
-
- This method was kept for backward-compatibility with pre-1.0 versions.
