Guide to downloading a CSV file directly from a webpage built with vue.js

Delving into the world of vue.js, I find myself pondering over how to incorporate a download link in my webpage for a CSV file stored locally.

In my component Template.vue, I have the following structure:

<a :href="item.loc" download>  {{item.title}} </a>

My export section looks like this:

export default {
  name: 'Template',
  data () {
    return {
      item: {loc: require("../assets/example.csv")}
    }
  }
}

Unfortunately, my current setup does not seem to support CSV files. When attempting to execute the code with a CSV file, I encountered the following error message:

"./src/assets/example.csv Module parse failed: Unexpected token (1:14) You may need an appropriate loader to handle this file type."

On the other hand, downloading an image (png) seems to work just fine. How can I tackle this issue? Is there a way to integrate a loader or are there alternative solutions available?

Answer №1

Do you happen to be utilizing vue-cli? If so, it is possible that you could implement something along the lines of this:

import csvData from "../assets/sample.csv"

export default {
  name: "Template",
  data() {
    return {
      info: csvData
    }
  }
}

// Within your template

<a :href="info"> </a>

If your CSV file remains static and unchanging, you may consider treating it as a fixed asset and simply link to its directory path. I am not as up-to-date with Vue as I used to be, but based on a quick review of the documentation, it seems feasible to place your CSV file in the static folder and reference it like so:

<a href="./assets/sample.csv">{{title}}</a>

Here is the solution I came across:

1) To begin, install the loader by running npm i csv-loader -D. 2) Next, insert the following code into your vue.config.js file:

module.exports = {
       chainWebpack: config => {
        config
          .module
          .rule('csv')
          .test(/\.csv$/)
          .use('csv-loader')
          .loader('csv-loader')
          .options({
             dynamicTyping: true,
             header: true,
            skipEmptyLines: true
          })
           .end()
   }
}

3) Afterward, you can import local files into your components, where the file will automatically be converted to a JavaScript object:

    import csv from './assets/file.csv'
    export default{
      created(){
        console.log(csv)
    }
  }
