如何在从原始加载器导入文本并使用showdown格式化时在VueJS中保留换行符

npm install showdown

<template>
  <div>
    <pre>{{ formattedText }}</pre>
  </div>
</template>

<script>
import showdown from 'showdown';
import textFile from '@/assets/textFile.txt';

export default {
  data() {
    return {
      formattedText: '',
    };
  },
  mounted() {
    this.formatText();
  },
  methods: {
    async formatText() {
      const response = await fetch(textFile);
      const rawText = await response.text();

      const converter = new showdown.Converter();
      const formattedText = converter.makeHtml(rawText);

      this.formattedText = formattedText;
    },
  },
};
</script>
