What's a jszip?

Jszip is a JavaScript library that creates zip archives directly on your browser.

Two why use Jszip

When a large number of configuration files (TXT or JSON) need to be downloaded from the server in the game,

You can compress the file into a zip package and unzip it after downloading it in Egret.

When the configuration file is only a few, but there are 50 60, I think it is necessary to put in the zip package.

Previously in a listed game company with Egret developed projects, there are a considerable number of configuration files, is placed in a zip package to download.

Three If you use Jszip

First download the Jszip third-party library, Egret on GitHub: https://github.com/egret-labs/egret-game-library

Put Jszip in the project directory, where you choose, as long as the configuration to add the path is correct.

Third-party libraries are then referenced in Egret, and the Egretproperties.json file in the project directory is added

{  "native": {    "Path_ignore": []  },  "Publish": {    "Web":0,    "native":1,    "Path":"Bin-release"  },  "egret_version":"3.0.6",  "Modules": [    {      "name":"Egret"    },    {      "name":"Game"    },    {      "name":"Tween"    },    {      "name":"Res"    },    {    "name": "Jszip", "path": "Jszip"    }  ]}

Create a new TXT test file a.txt, which says "a"

Compress the a.txt into a assets.zip test package

Put it under the Resource/assets folder

Load this zip package in Egret, then unzip the a.txt inside and output the contents.

Res.getresbyurl ("resource/assets/assets.zip", function (data) {       var  New  jszip (data);       Console.log (Zip.file ("a.txt"). Astext ());  // output A},this, RES. Resourceitem.type_bin);

Of course, A.txt is JSON, and the output string can be converted to JSON to use

var json = Json.parse (Zip.file ("a.txt"). Astext ());
