nodejs-api-starter VS notion-api-worker

(1) React + API monorepo VS (2) React + API as separate repositories

Nope. Just plain GraphQL.js + Knex.js (example), often typed manually since it's not where most of the time spend on when building an API server (though it can be automated via a scaffolding script if there are too many db tables). Generating TypeScript definitions off the actual db schema using knex-types (example).

Examples: - https://github.com/kriasoft/node-starter-kit - basic Node.js API starter kit - https://github.com/kriasoft/graphql-starter - monorepo template with GraphQL, React, Relay

https://github.com/kriasoft/graphql-starter - See web/relay.config.js, run: yarn relay

Your first example is the code-first development approach (example), while the latter one is schema-first, popularized by Apollo.

Source code (example): https://github.com/kriasoft/graphql-starter

Here is yet another example of a Node.js (Express) middleware that encodes/decodes JWT (OAuth) token into a session cookie: https://github.com/kriasoft/graphql-starter/blob/main/api/session.ts

Details: It's going to be a Reddit-like community but for books. Just started working on this idea last week (solo) by branching out from graphql-starter open source template. Looking for feedback and feature requests.

Yes, for example:

There's one small problem with this strategy though: the image URLs are not permanent and all our pages suddenly have broken image links. Digging around, I've found this Github issue that more or less describes our problem, but the fix doesn't apply to the official API. Is there a way to build Notion blocks but with image links that doesn't expire a few hours later?

So, React Notion use Notion API Worker to handle its requests. It can be also self-hosted using Cloudfare. Cloudflare offers a generous free plan with up to 100,000 request per day.

If you are looking to be able to synchronize an embedded widget with other content in Notion, it is possible to use the content of public Notion pages to adjust a widget's state. This however requires using an open-source, unofficial tool like notion-api-worker or notion-client.
