ethereumjs - Browser Builds
This repository contains browser builds of the following ethereumjs libraries:
這個儲存庫包含以下ethereumjs庫的瀏覽器構建（其實就是將下面的ethereumjs庫構造成瀏覽器能夠使用的js檔案形式）
- ethereumjs-vm
- ethereumjs-tx
- ethereumjs-wallet
- ethereumjs-wallet-hd
- ethereumjs-wallet-thirdparty
- ethereumjs-icap
- ethereumjs-abi
- ethereumjs-all
They are built using browserify with a known set of working dependencies.
使用帶著具有一組已知的工作依賴項的browserify來構建
For every library/build collection there is a larger plain source version also including the source mappings (e.g. ethereumjs-vm-x.x.x.jsethereumjs-vm-x.x.x.min.js).
這裡對每個庫/構建收集有一個更大的包含資源對映(比如ethereumjs-vm-x.x.x.js) 的純資源版本，以及在生產時使用的簡化版本 (比如ethereumjs-vm-x.x.x.min.js)
Note注意:
This repository was just lately (October 2017) revived. Currently all builds are considered experimental
這個儲存庫最近（2017/10）才恢復使用。目前，從API的穩定性、功能和安全性來看，所有構建都是實驗性的
Usage使用
In your web application, include only one of the builds from the dist directory. All exports will be available under the global ethereumjs.
在你的web應用中，只包含來自dist目錄之一的構建。在全域性變數ethereumjs下，所有的構建都是可用的
Note: all packages expect ECMAScript 6 (ES6) as a minimum environment. From browsers lacking ES6 support, please use a shim (like es6-shim) before including any of the builds from this repo.
注意：所有包都期待使用 ECMAScript 6 (ES6) 作為最小的環境。如果瀏覽器缺少ES6支援，從該儲存庫中包含任何構建之前，請使用shim(like es6-shim)
Examples例子
Examples for usage of the browser builds can be found in the examples directory:

Start an http-server from the main directory of the repository to run the examples in the browser.
從儲存庫的主目錄開啟 http-server去在瀏覽器中執行該例子
Build構建
Builds are done using the .js exports compilation files from the src/ directory and using the build.js script from the main directory to create the build in the dist/ folder.
構建的完成需要先從src/資料夾中使用.js輸出編譯檔案，然後使用來自主目錄的build.js指令碼在dist/資料夾中建立構建
Version numbers for the builds are directly extracted from the versions installed in the local node_modules folder.
構建的版本數目直接從安裝在本地的node_modules資料夾的版本中抽取出。
For creating new builds:為了建立新的構建
- Change
package.jsonto require desired/up-to-date versions of the libraries 改變package.json去獲取想要的/最新版本的庫
package.json

2.Reinstall/update local node_modules packages 重新安裝/更新本地node_modules包
執行npm install
3.Run npm run build to generate new set of builds 執行npm run build命令去生成新構建集

然後你的dist資料夾下就會得到你想要的構建了，然後你就能夠在頁面端使用這些構建了，就像上面的例子一樣
