From 7603da71a535481e3fc60e38b013abf78516d322 Mon Sep 17 00:00:00 2001 From: Damien Arrachequesne Date: Sat, 17 Oct 2020 01:56:17 +0200 Subject: [PATCH] feat: remove prod dependency to socket.io-client The client bundles are included in the repository in order to remove socket.io-client from the list of production dependencies and thus to reduce the total number of dependencies when installing the server. This means the release of the client and the server must now be in sync (which is almost always the case actually). The minified build is now served: - //socket.io.js - //socket.io.js.map - //socket.io.min.js - //socket.io.min.js.map The content will now be compressed as well. --- client-dist/socket.io.js | 6084 ++++++++++++++++++++++++++++++ client-dist/socket.io.js.map | 1 + client-dist/socket.io.min.js | 7 + client-dist/socket.io.min.js.map | 1 + lib/index.ts | 131 +- package.json | 3 +- test/socket.io.ts | 48 +- 7 files changed, 6206 insertions(+), 69 deletions(-) create mode 100644 client-dist/socket.io.js create mode 100644 client-dist/socket.io.js.map create mode 100644 client-dist/socket.io.min.js create mode 100644 client-dist/socket.io.min.js.map diff --git a/client-dist/socket.io.js b/client-dist/socket.io.js new file mode 100644 index 0000000000..4b64aa7cb6 --- /dev/null +++ b/client-dist/socket.io.js @@ -0,0 +1,6084 @@ +/*! + * Socket.IO v3.0.0-rc2 + * (c) 2014-2020 Guillermo Rauch + * Released under the MIT License. + */ +(function webpackUniversalModuleDefinition(root, factory) { + if(typeof exports === 'object' && typeof module === 'object') + module.exports = factory(); + else if(typeof define === 'function' && define.amd) + define([], factory); + else if(typeof exports === 'object') + exports["io"] = factory(); + else + root["io"] = factory(); +})((() => { + if (typeof self !== 'undefined') { + return self; + } else if (typeof window !== 'undefined') { + return window; + } else if (typeof global !== 'undefined') { + return global; + } else { + return Function('return this')(); + } + })(), function() { +return /******/ (function(modules) { // webpackBootstrap +/******/ // The module cache +/******/ var installedModules = {}; +/******/ +/******/ // The require function +/******/ function __webpack_require__(moduleId) { +/******/ +/******/ // Check if module is in cache +/******/ if(installedModules[moduleId]) { +/******/ return installedModules[moduleId].exports; +/******/ } +/******/ // Create a new module (and put it into the cache) +/******/ var module = installedModules[moduleId] = { +/******/ i: moduleId, +/******/ l: false, +/******/ exports: {} +/******/ }; +/******/ +/******/ // Execute the module function +/******/ modules[moduleId].call(module.exports, module, module.exports, __webpack_require__); +/******/ +/******/ // Flag the module as loaded +/******/ module.l = true; +/******/ +/******/ // Return the exports of the module +/******/ return module.exports; +/******/ } +/******/ +/******/ +/******/ // expose the modules object (__webpack_modules__) +/******/ __webpack_require__.m = modules; +/******/ +/******/ // expose the module cache +/******/ __webpack_require__.c = installedModules; +/******/ +/******/ // define getter function for harmony exports +/******/ __webpack_require__.d = function(exports, name, getter) { +/******/ if(!__webpack_require__.o(exports, name)) { +/******/ Object.defineProperty(exports, name, { enumerable: true, get: getter }); +/******/ } +/******/ }; +/******/ +/******/ // define __esModule on exports +/******/ __webpack_require__.r = function(exports) { +/******/ if(typeof Symbol !== 'undefined' && Symbol.toStringTag) { +/******/ Object.defineProperty(exports, Symbol.toStringTag, { value: 'Module' }); +/******/ } +/******/ Object.defineProperty(exports, '__esModule', { value: true }); +/******/ }; +/******/ +/******/ // create a fake namespace object +/******/ // mode & 1: value is a module id, require it +/******/ // mode & 2: merge all properties of value into the ns +/******/ // mode & 4: return value when already ns object +/******/ // mode & 8|1: behave like require +/******/ __webpack_require__.t = function(value, mode) { +/******/ if(mode & 1) value = __webpack_require__(value); +/******/ if(mode & 8) return value; +/******/ if((mode & 4) && typeof value === 'object' && value && value.__esModule) return value; +/******/ var ns = Object.create(null); +/******/ __webpack_require__.r(ns); +/******/ Object.defineProperty(ns, 'default', { enumerable: true, value: value }); +/******/ if(mode & 2 && typeof value != 'string') for(var key in value) __webpack_require__.d(ns, key, function(key) { return value[key]; }.bind(null, key)); +/******/ return ns; +/******/ }; +/******/ +/******/ // getDefaultExport function for compatibility with non-harmony modules +/******/ __webpack_require__.n = function(module) { +/******/ var getter = module && module.__esModule ?
