javascript + hive api (bridge), to fetch ALL posts for a certain tag.

<!DOCTYPE html>
    api url:
    <input id="api_url_field">
    <input id="tag_field">
    <button id="go_button">GO</button>    

let api_url=""
let tag = "mc2022"

let api_url_field = document.getElementById("api_url_field")
let tag_field = document.getElementById("tag_field")
let go_button = document.getElementById("go_button")

api_url_field.value = api_url
tag_field.value = tag

let get_posts = async(api_url, tag, start_author = "", start_permlink = "") => {
    let fetched = await fetch(
        api_url, {
            method: "POST",
            body: JSON.stringify({

let go = async() => {

go_button.onclick = go


Node operators will probably hate me for dumping this, but I don't really care anymore.

Save this as scrape_tag.html and open in browser

right-click -> 'inspect'
go to console:


(screenshot made in firefox browser)

This should work for any device that has a browser.

These are all posts with the tag #mc2022, sorted by date (latest first)
If you need to export those as CSV or whatever, I can also build that, but since gatekeeping is the thing here, I feel like I have given away enough for free. Learn to code, or contact me directly.

For someone actually trying to build something, this should be much more helpful than all examples provided under combined.
No virtual environment needed, no libraries, no weird fluff.

You are welcome

Now follow me, vote this and start flaming.
