This time I will bring you the case conversion between json and array key values. What are the precautions for case conversion between json and array key values? The following is a practical case, let's take a look.
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}]}}]] }); })
