Plausible with Node.js

[ZachSaucier]

Don't use plausible-tracker-node

I mainly wanted to make this post to say don't use plausible-tracker-node. I used it for a few hours successfully then ran into an issue of it throwing unhandled promise errors related to 429 requests even though I was way below Plausible's API maximum.

Node.js + Express.js helper class for Plausible

I ended up writing a little class for Plausible's Events API to use in my Node.js / Express.js app which I might as well share also:

class Plausible {
  domain = "";

  constructor(domain) {
    this.domain = domain;
  }

  trackPageview(req, rest) {
    this.trackEvent("pageview", req, rest);
  }

  trackEvent(name, req, { props, revenue } = {}) {
    const body = {
      domain: this.domain,
      name: name,
      url: `${req.protocol}://${req.get("host")}${req.originalUrl}`,
      referrer: req.get("Referrer"),
    };

    if (props) {
      body.props = props;
    }

    if (revenue) {
      body.revenue = revenue;
    }

    fetch("https://plausible.io/api/event", {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "X-Forwarded-For": req.socket.remoteAddress,
        "Content-Type": "application/json",
      },
      body: JSON.stringify(body),
    }).catch((err) => console.error("Plausible error", err));
  }
}

Usage:

const plausible = new Plausible(MY_DOMAIN);

plausible.trackPageview(req);

plausible.trackEvent("404", req);
