Question

什麼是部署節點應用程序依賴項的最佳方式。如何確保使用npm安裝某個軟件包的某些版本。是否有配方文件作爲與Python的pip requirements.txt？

Answer 1

A package.json指定模塊的依賴關係。

https://docs.npmjs.com/files/package.json#dependencies

{ "dependencies" : 
    { "foo" : "1.0.0 - 2.9999.9999" 
    , "bar" : ">=1.0.2 <2.1.2" 
    , "baz" : ">1.0.2 <=2.3.4" 
    , "boo" : "2.0.1" 
    , "qux" : "<1.0.0 || >=2.3.1 <2.4.5 || >=2.5.2 <3.0.0" 
    , "asd" : "http://asdf.com/asdf.tar.gz" 
    , "til" : "~1.2" 
    , "elf" : "~1.2.3" 
    , "two" : "2.x" 
    , "thr" : "3.3.x" 
    , "lat" : "latest" 
    , "dyl" : "file:../dyl" 
    } 
}
