How to get dev.to posts from the API

I've decided to download my dev.to posts so that I can store them in git. That means that if the site ever goes down, I have a copy of my blog content. The API is documented here.

The following endpoint will give a list of articles: https://dev.to/api/articles?username=melvincarvalho

It supports pagination, each page will contain 30 articles by default.

Replace melvincarvalho with your own username

So I wrote a JavaScript script that will pull out my articles.

#!/usr/bin/env node

// requires
const argv = require('minimist')(process.argv.slice(2))
const $ = require('child_process').execSync
const fs = require('fs')

// data
globalThis.data = {
  user: 'melvincarvalho',
  api: 'https://dev.to/api/articles/',
  datadir: '.'
}

// init
data.user = argv._[0] || data.user
data.api = argv.api || data.api
data.datadir = argv.datadir || data.datadir
console.log('data', data)

// main
const useruri = `${data.api}?username=${data.user}`
const cmd = `curl ${useruri}`
console.log('cmd', cmd)

const json = JSON.parse($(cmd).toString())
const output = JSON.stringify(json, null, 2)
const outfile = `${data.datadir}/posts.json`
console.log('output', output)

fs.writeFileSync(outfile, output)
Enter fullscreen modeExit fullscreen mode

Usage: ./getposts.js [username]

First we initialize the endpoint and username. Then we run some curl to get the result, and finally we format it and write it to a file.

The JSON output can be seen here and the current script is here

Now that I have a list of articles, it should be possible to download the markdown from individual articles too. I will hopefully cover that in a future post.
