params-mapper

将前端页面参数映射到返回给服务端的参数

Code this:

``js
const paramsMapper = require('params-mapper');
const BaseParamObject = paramsMapper.BaseParamObject;
const autoTransfer = paramsMapper.autoTransfer;

const TransformationPayload = {
emptyObject: {
paramKey: 'empty_object',
alwaysKeep: true,
},
emptyObjectNotKeep: {
paramKey: 'empty_object_not_keep',
},
notEmptyObject: {
paramKey: 'not_empty_object',
},

emptyArray: {
paramKey: 'empty_array',
alwaysKeep: true,
},
emptyArrayNotKeep: {
paramKey: 'empty_array_not_keep',
},
notEmptyArray: {
paramKey: 'not_empty_array',
},
};

const payload = {
emptyObject: {},
emptyObjectNotKeep: {},
notEmptyObject: { a: 1 },

emptyArray: [],
emptyArrayNotKeep: [],
notEmptyArray: [1, 2, 3],
};

class A extends BaseParamObject {}
autoTransfer(TransformationPayload)(A);

// 或者
// or this:
const A = autoTransfer(TransformationPayload)(class extends BaseParamObject {});

const temp = new A(payload);
const params = temp.getParams();
console.log(params);
`

Result in:

`
{
"empty_object": {},
"not_empty_object": {
"a": 1
},
"empty_array": [],
"not_empty_array": [
1,
2,
3
]
}
