vue-codemirror json格式化精度数据丢失 json-bigint

const key = '{"a":1, "b":1.00000000000000000,"key": 1234567890123456789}'
      const JSONbigString = require('json-bigint')({storeAsString: true})
      const withString = JSONbigString.parse(key)
      console.log('key：', key)
      console.log('jsonBigint：', withString)
      console.log('jsonParse：', JSON.parse(key))
      this.codemirror.setValue((JSON.stringify(withString, null, 2)))
