ws chat example

From 6abf126c2a7a451cded8c6b5e6ddf1b69c84055d Mon Sep 17 00:00:00 2001 From: Casper Beyer Date: Tue, 2 Feb 2021 19:05:46 +0800 Subject: chore: remove std directory (#9361) This removes the std folder from the tree. Various parts of the tests are pretty tightly dependent on std (47 direct imports and 75 indirect imports, not counting the cli tests that use them as fixtures) so I've added std as a submodule for now. --- std/examples/chat/index.html | 81 ---------------------------------------- std/examples/chat/server.ts | 81 ---------------------------------------- std/examples/chat/server_test.ts | 81 ---------------------------------------- 3 files changed, 243 deletions(-) delete mode 100644 std/examples/chat/index.html delete mode 100644 std/examples/chat/server.ts delete mode 100644 std/examples/chat/server_test.ts (limited to 'std/examples/chat') diff --git a/std/examples/chat/index.html b/std/examples/chat/index.html deleted file mode 100644 index 2daf288b3..000000000 --- a/std/examples/chat/index.html +++ /dev/null @@ -1,81 +0,0 @@ - - - - ws chat example - - -
