Looks interesting.
It seems to abstract the part about the client messaging the backend, which focuses on being able to easily plug in a number of Front-end web framework to manage client state.
Has the "main web API is the same as the REST API" focus, which is fundamental 2020-nowadays.
Uses Socket.IO, which allows the client Javascript to register callbacks when data is updated to achieve Socket.IO, e.g. their default chat app does:
client.service('messages').on('created', addMessage);
so that message appear immediately as they are sent.
Their standard template from feathers generate app on @feathersjs/cli@4.5.0 includes:
  • several authentication methods, including OAuth
  • testing
  • backend database with one of several object-relational mapping! However, they don't abstract across them. E.g., the default Chat example uses NeDB, but a real app will likely use Sequelize, and a port is needed
which looks promising! They don't have a default template for a Front-end web framework however unfortunately: docs.feathersjs.com/guides/frameworks.html#the-feathers-chat lists a few chat app versions, which is their hello world:
But it is in itself a completely boring app with a single splash page, and no database interaction, so not a good showcase. The actual showcase app is feathersjs/feathers-chat.
And there is no official example of the chat app that is immediately deployable to Heroku: FeathersJS Heroku deployment, all setups require thinking.
Global source entry point: determine on package.json as usual, defaults to src/index.js.
The main FeathersJS hello world demo. Notable missing things...
The default feathers-chat app runs on NeDB (local filesystem JSON database).
Last updated 2018 as of 2021, but still just worked.
Also uses webpack which is fantastic.
Gotta run github.com/feathersjs/feathers-chat first: github.com/feathersjs-ecosystem/feathers-chat-react/issues/5, then it worked:
git clone https://github.com/feathersjs/feathers-chat
cd feathers-chat
git checkout fd729a47c57f9e6170cc1fa23cee0c84a004feb5
npm install
npm start
and on the other terminal:
git clone https://github.com/feathersjs-ecosystem/feathers-chat-react
cd feathers-chat-react
git checkout 36d56cbe80bbd5596f6a108b1de9db343b33dac3
npm install
npm start
then visit localhost:3000/ and you can create an account and login, tested on Ubuntu 20.10. Data is stored on persistently.
TODO how to merge those two repos into a single repo.
If you disable JavaScript on Chromium, it stops working completely. There is a section on how to solve that at: docs.feathersjs.com/cookbook/express/view-engine.html but it does not cover React specifically. Codaisseur/feathersjs-react-redux-ssr might be good to look into.
Also webpack and Babel, looks promising!
As of 2021, last commit from 2017.
git clone https://github.com/Codaisseur/feathersjs-react-redux-ssr
cd feathersjs-react-redux-ssr
npm install
failed on Ubuntu 20.10 Node.js v14.15.3 with:
../src/create_string.cpp:17:37: error: no matching function for call to ‘v8::String::Utf8Value::Utf8Value(v8::Local<v8::Value>&)’
   17 |   v8::String::Utf8Value string(value);
      |                                     ^
Likely similar bullshit from: stackoverflow.com/questions/50111688/node-sqlite-node-gyp-build-error-no-member-named-forceset-in-v8object because the Node.js version is too new.
If I try nvm install v10
I Google error messages until reaching:

So once you install MongoDB, run with:
MONGODB_FEATHERS_REALWORLD=mongodb://localhost:27017/mydb npm start
Tests can be run with:
MONGODB_FEATHERS_REALWORLD=mongodb://localhost:27017/mydb npm run test
but there were 10 failures and 55 passes: github.com/randyscotsmithey/feathers-realworld-example-app/issues/3
One major step was to port to PostgreSQL as shown at feathers-chat PostgreSQL.
There's also a heroku branch at: github.com/feathersjs/feathers-chat/tree/heroku, but it also seems to use NeDB? So you can have a filesystem in Heroku? Doesn't seem so: stackoverflow.com/questions/42775418/heroku-local-persistent-storage
