Migrate MongoDB collection to SQLite DB table using Javascript/Deno

main.js

import { DB as SqliteDB } from "https://deno.land/x/sqlite/mod.ts"
import { MongoClient } from "https://deno.land/x/[email protected]/mod.ts"

const sqlite_db = new SqliteDB("out.db")
sqlite_db.query('drop table if exists posts')
sqlite_db.query("CREATE TABLE posts (id INTEGER PRIMARY KEY AUTOINCREMENT, message TEXT)")

const client = new MongoClient()
await client.connect("mongodb://localhost:27017")
const mongo_db = client.database("my-db")

console.log('migrate posts...')
const posts_count = await mongo_db.collection("post").count()
await mongo_db.collection("post").find().forEach((post, i) => {
    if(i % 1000 == 0)
        console.log(Math.round(i/posts_count*100*100)/100 + ' %')
    sqlite_db.query("INSERT INTO posts (id, message) VALUES (?, ?)", [post.post_id, post.message])
})
