Since becoming maintainer of this project, and making some security updates, we have not been able to get the electron build working. This is why there has not been a release in a while.

This is no small undertaking, but very very important!

Bug description

When i was copying repo to contribute i encountered that in order to build "client" package i had to install YARN globally, although in the CONTRIBUTING.md it is not mentioned.
Here's the usage place that was failing for me before i installed YARN:
https://github.com/prisma/prisma/blob/284891a1d04a1d98f358b5cd141c79c0106ed0c3/src/packages/sdk/src/getPackedPackage.ts#L48

What do you want and why?

const query = {}
cosnt params = useParams() // returns {}
cosnt params = useParams('number') // returns {}
const param = useParam('key', "number") // returns NaN

1. I want to check param like if(param) but NaN will be true. It might not be useful.
2. Between useParams and param is not consistent, I'm a bit confusing.
3. Type implementati

It should be easy to navigate back. Right now there's no built-in way to do this. We already use navigate to navigate programatically. It might make sense to add the back-navigation feature there:

navigate.back()

The way it's done natively with web apis is via history's back and go properties. back does what you would expect, and go takes a number, so you can go back mult

When deploying or publishing new version, counter is indicating invalid time (-1h -1m -2s) and counting forward for few seconds and then it going back to normal and start from 0.

To Reproduce

1. Make a change in your app (add new entity)
2. Commit and publish your changes
3. Look at the counter below
