今回したいこと
- 日本の電話番号(03-1234-5678)などを、E.164表記(+81312345678)に変換したい
- ついでにバリデーションも出来るといいかも
環境
- Node.js
ライブラリ
Googleが提供している電話番号をバリデーションと自動フォーマット可能なlibphonenumberのnpm版であるgoogle-libphonenumberを使用します。
google-libphonenumberの使用方法
インストール
npm install google-libphonenumber
例１）'202-456-1414'を'US'のE164表記に変換
// Require `PhoneNumberFormat`.constPNF=require('google-libphonenumber').PhoneNumberFormat;// Get an instance of `PhoneNumberUtil`.constphoneUtil=require('google-libphonenumber').PhoneNumberUtil.getInstance();// Parse number with country code and keep raw input.constnumber=phoneUtil.parseAndKeepRawInput('202-456-1414','US');// Format number in the E164 format.console.log(phoneUtil.format(number,PNF.E164));// => +12024561414例２）全角・半角混合の日本の電話番号をE164表記に変換
// Require `PhoneNumberFormat`.constPNF=require('google-libphonenumber').PhoneNumberFormat;// Get an instance of `PhoneNumberUtil`.constphoneUtil=require('google-libphonenumber').PhoneNumberUtil.getInstance();constphoneNumbers=['０３―１１１１―２２２２','０３ １１１１ ２２２２','（０３）１１１１-２２２２','0312345678','03 1234 5678','03-1234-5678','(03)-1234-5678','09012345678','090-1234-5678','０９０１２３４５６７８','０９０―１２３４―５６７８','0120-123-123']constreplacedNumbers=phoneNumbers.map(phoneNumber=>{constreplacedNumber=formatNumber(phoneNumber);returnreplacedNumber;})functionformatNumber(str){constnumber=phoneUtil.parseAndKeepRawInput(str,'JP');returnphoneUtil.format(number,PNF.E164);}console.log(replacedNumbers);// =>["+81311112222","+81311112222","+81311112222","+81312345678","+81312345678","+81312345678","+81312345678","+819012345678","+819012345678","+819012345678","+819012345678","+81120123123"]その他の使い方

バリデーションも出来そうです。

最初はgoogle-libphonenumberを知らなかったので、正規表現でやってみました。
constphoneNumbers=['０３―１１１１―２２２２','０３ １１１１ ２２２２','（０３）１１１１-２２２２','0312345678','03 1234 5678','03-1234-5678','(03)-1234-5678','09012345678','090-1234-5678','０９０１２３４５６７８','０９０―１２３４―５６７８','0120-123-123']constreplacedNumbers=phoneNumbers.map(phoneNumber=>{constreplacedNumber=toE164Number(phoneNumber);returnreplacedNumber;})functiontoE164Number(strVal){// 半角変換consthalfVal=strVal.replace(/[！-～]/g,function(tmpStr){// 文字コードをシフトreturnString.fromCharCode(tmpStr.charCodeAt(0)-0xFEE0);});console.log("halfVal",halfVal);// 文字の変換constnumber=phoneUtil.parseAndKeepRawInput(halfVal,'JP');console.log(number)console.log(phoneUtil.format(number,PNF.E164));returnhalfVal.replace(/[\-\s+()－―]/gi,'').replace('0','+81');}最後に
google-libphonenumberはかなり便利だなと思いました。
ただ電話番号を変換するときにJPなどの国コードを指定しないといけないので、素の電話番号形式から国コードを判定するものがあればいいんですけどね。。
