Detailed explanation of the deep case conversion problem of json objects and array key values

This article mainly introduces you to the relevant information about the in-depth case conversion of json objects and array key values. The article introduces it in great detail through sample code, which has certain reference learning value for everyone's study or work. Friends who need it, please study together below.

Preface

I was working on a project recently and found that all the data key values ​​returned by the backend are in uppercase letters, which is sometimes used by the frontend. It's very inconvenient, so I wrote a small deep conversion tool to share with everyone, so that I don't have to reinvent the wheel. If you don't like it, don't criticize it. I won't say much below, let's take a look at the detailed introduction.

start

npm i deep-lu-trans --save

json example

import t from 'deep-lu-trans';
const obj = {
 AS_DD_S: 123213,
 AND_SAJ_JDK_JSAKD_: {
 DJK_ASJ: {
  SA_DSA_DSA: 123123,
  ASDA_SDH_KAS: {
  ASD_SAD: [{
   ASD_SAD_SA: 123123,
   III_ASDA: [1, 23, {
   ASD_SAD: 123
   }]
  }]
  }
 }
 },
 KIO: [{
 OP: 1,
 OOP: 2
 }, {
 OL: 1,
 OP: 2
 }]
};

t.objKeysToLower(obj).then((res) => {
 console.log(JSON.stringify(res));

});
t.objKeysToLower(obj).then((res) => {
 console.log(JSON.stringify(res));
 /*
 {"as_dd_s":123213,"and_saj_jdk_jsakd_":{"djk_asj":{"sa_dsa_dsa":123123,"asda_sdh_kas":{"asd_sad":[{"asd_sad_sa":123123,"iii_asda":[1,23,{"asd_sad":123}]}]}}},"kio":[{"op":1,"oop":2},{"ol":1,"op":2}]}
 */
 t.objKeysToUpper(res).then((_s) => {
 console.log(JSON.stringify(_s));
 /*
 {"AS_DD_S":123213,"AND_SAJ_JDK_JSAKD_":{"DJK_ASJ":{"SA_DSA_DSA":123123,"ASDA_SDH_KAS":{"ASD_SAD":[{"ASD_SAD_SA":123123,"III_ASDA":[1,23,{"ASD_SAD":123}]}]}}},"KIO":[{"OP":1,"OOP":2},{"OL":1,"OP":2}]}
  */
 });
});

array example

import t from 'deep-lu-trans';

const arr = [{
 A_B: 1,
 B_C: 2
}, 3, 4, 'abc', [{
 A_B: 1,
 B_C: {
 C_D: [0, {
  CK: 1,
  KL: 2
 }]
 }
}]]

t.arrKeysToLower(arr).then((res) => {
 console.log(JSON.stringify(res));
 /*
 [{"a_b":1,"b_c":2},3,4,"abc",[{"a_b":1,"b_c":{"c_d":[0,{"ck":1,"kl":2}]}}]]
 */
 t.arrKeysToUpper(res).then((_s) => {
 console.log(JSON.stringify(_s));
 [{"A_B":1,"B_C":2},3,4,"abc",[{"A_B":1,"B_C":{"C_D":[0,{"CK":1,"KL":2}]}}]]
 });
})

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
