Answer 1

I have tried, and I'm sure that using response.data.pipe and fs.createWriteStream can work.

Besides, I want to add my situation and solution

Situation:

• using koa to develop a node.js server
• using axios to get a pdf via url
• using pdf-parse to parse the pdf
• extract some information of pdf and return it as json to browser

Solution:

const Koa = require('koa');
const app = new Koa();
const axios = require('axios')
const fs = require("fs")
const pdf = require('pdf-parse');
const utils = require('./utils')

app.listen(process.env.PORT || 3000)

app.use(async (ctx, next) => {
      let url = 'https://path/name.pdf'
      let resp = await axios({
          url: encodeURI(url),
          responseType: 'arraybuffer'
        })

        let data = await pdf(resp.data)

        ctx.body = {
            phone: utils.getPhone(data.text),
            email: utils.getEmail(data.text),
        }
})

In this solution, it doesn't need to write file and read file, it's more efficient.
