|
---|
223 | * remove Server#set() method ([029f478](https://github.com/socketio/socket.io/commit/029f478992f59b1eb5226453db46363a570eea46))

|
---|
229 | ### BREAKING CHANGES
|
---|
230 |
|
---|
231 | * the Socket#use() method is removed (see [5c73733](https://github.com/socketio/socket.io/commit/5c737339858d59eab4b5ee2dd6feff0e82c4fe5a))
|
---|
232 |
|
---|
233 | * Socket#join() and Socket#leave() do not accept a callback argument anymore.
|
---|
234 |
|
---|
235 | Before:
|
---|
236 |
|
---|
237 | ```js
|
---|
238 | socket.join("room1", () => {
|
---|
239 | io.to("room1").emit("hello");
|
---|
240 | });
|
---|
241 | ```
|
---|
242 |
|
---|
243 | After:
|
---|
244 |
|
---|
245 | ```js
|
---|
246 | socket.join("room1");
|
---|
247 | io.to("room1").emit("hello");
|
---|
248 | // or await socket.join("room1"); for custom adapters
|
---|
249 | ```
|
---|
250 |
|
---|
251 | * the "connected" map is renamed to "sockets"
|
---|
252 | * the Socket#binary() method is removed, as this use case is now covered by the ability to provide your own parser.
|
---|
253 | * the 'origins' option is removed
|
---|
254 |
|
---|
255 | Before:
|
---|
256 |
|
---|
257 | ```js
|
---|
258 | new Server(3000, {
|
---|
259 | origins: ["https://example.com"]
|
---|
260 | });
|
---|
261 | ```
|
---|
262 |
|
---|
263 | The 'origins' option was used in the allowRequest method, in order to
|
---|
264 | determine whether the request should pass or not. And the Engine.IO
|
---|
265 | server would implicitly add the necessary Access-Control-Allow-xxx
|
---|
266 | headers.
|
---|
267 |
|
---|
268 | After:
|
---|
269 |
|
---|
270 | ```js
|
---|
271 | new Server(3000, {
|
---|
272 | cors: {
|
---|
273 | origin: "https://example.com",
|
---|
274 | methods: ["GET", "POST"],
|
---|
275 | allowedHeaders: ["content-type"]
|
---|
276 | }
|
---|
277 | });
|
---|
278 | ```
|
---|
279 |
|
---|
280 | The already existing 'allowRequest' option can be used for validation:
|
---|
281 |
|
---|
282 | ```js
|
---|
283 | new Server(3000, {
|
---|
284 | allowRequest: (req, callback) => {
|
---|
285 | callback(null, req.headers.referer.startsWith("https://example.com"));
|
---|
286 | }
|
---|
287 | });
|
---|
288 | ```
|
---|
289 |
|
---|
290 | * Socket#rooms is now a Set instead of an object
|
---|
291 |
|
---|
292 | * Namespace#connected is now a Map instead of an object
|
---|
293 |
|
---|
294 | * there is no more implicit connection to the default namespace:
|
---|
295 |
|
---|
296 | ```js
|
---|
297 | // client-side
|
---|
298 | const socket = io("/admin");
|
---|
299 |
|
---|
300 | // server-side
|
---|
301 | io.on("connect", socket => {
|
---|
302 | // not triggered anymore
|
---|
303 | })
|
---|
304 |
|
---|
305 | io.use((socket, next) => {
|
---|
306 | // not triggered anymore
|
---|
307 | });
|
---|
308 |
|
---|
309 | io.of("/admin").use((socket, next) => {
|
---|
310 | // triggered
|
---|
311 | });
|
---|
312 | ```
|
---|
313 |
|
---|
314 | * the Server#set() method was removed
|
---|
315 |
|
---|
316 | This method was kept for backward-compatibility with pre-1.0 versions.
