For FREE, Error notification tool. This provides you error reporting endpoint. You need just your slack webhook URL and Cloud infrastructure. I recommend Vercel.

(In Japanese, Vercel 経由で Slack に通知を送れるやつ)

Why free

How to use

Create slack channel for error loggin.

Get webhook url to notify the channel.

Add incoming webhook app extension.

https://${your_slack_name}.slack.com/apps

Connect your channel

fork this repository
Conect forked repository to Vercel

Configure Vercel

Set your slack incoming hook url as Enviroment Varialbes. datacat send it log.

Project name is important. The name become your error logging endpoint's URL.

After set your project name, click 'Deploy'. You don't need to configure for build and so on. Because Vercel can build TypeScript and construct API without setting, if we use vercel's serverless functions. The detail is here.

post message to the endpoint

 axios
    .post("http://datacat-demo.vercel.app/api/report-dev-error", {
      message: "Hello from vercel!!",
    })
    .then(() => res.status(204).send(""))
    .catch(() => res.status(500).send("slack api error"));

curl -X POST -H "Content-Type: application/json" -d '{"message":"Hello from vercel!!"}' http://datacat-demo.vercel.app/api/report-dev-error
