# Introduction
Avoid having multiple `isDefined` definition across our pacakges
Also avoid importing `isDefined` from `twenty-ui` which exposes a huge
barrel for a such little util function
## In a nutshell
Removed own `isDefined.ts` definition from `twenty-ui` `twenty-front`
and `twenty-server` to move it to `twenty-shared`.
Updated imports for each packages, and added explicit dependencies to
`twenty-shared` if not already in place

Previously we had to create a separate API key to give access to chrome
extension so we can make calls to the DB. This PR includes logic to
initiate a oauth flow with PKCE method which redirects to the
`Authorise` screen to give access to server tokens.
Implemented in this PR-
1. make `redirectUrl` a non-nullable parameter
2. Add `NODE_ENV` to environment variable service
3. new env variable `CHROME_EXTENSION_REDIRECT_URL` on server side
4. strict checks for redirectUrl
5. try catch blocks on utils db query methods
6. refactor Apollo Client to handle `unauthorized` condition
7. input field to enter server url (for self-hosting)
8. state to show user if its already connected
9. show error if oauth flow is cancelled by user
