Federation package for node.js

GFT

During the federation protocol integration on our website (https://gft.network) we faced problems while installing the official Federation Server.

Our infrastructure is built on top of the Node.js and we are using MongoDB as primary database. Official server implementation doesn't work with MongoDB. Therefore we decided to implement Federation Server as a separate NPM module with extensible design that allows to use different providers for particular databases. It will be compatible with Express or any other Node framework.

We have already implemented basic functionality and some tests. We are using it on our website. However our developers still need some time to write the docs and run more comprehensive tests to ensure that our implementation is 100% compatible with official Stellar Federation Protocol.

We expect that it will be ready on the next week.

What do you think about the idea?
And what database providers we should implement in the first place?

Sounds like a good idea, I guess you already got MongoDB might also want to support postgress maybe sqlite and mysql. you should setup a demo we can point at and try from a few wallets to see how it goes with an test lookup name to try. For the demo we can point at testnet if your worried about faults to start.

sacarlson kratos_ng Thanks for your interest, guys!

I have finally published the NPM module: https://www.npmjs.com/package/stellar-federation-resolver-node
GitHub page: https://github.com/GFTNetwork/stellar-federation-resolver-node

We decided to change the data fetching approach to make the resolver more flexible.
Key benefits:

Works with any web framework (Express, Sails, Koa, Hapi, etc).
Allows you to design your own name resolution workflows: fetch data from db, external API, or just from plain file. No matter how complex logic you have, you can integrate it with a minimum of coding.
External "providers" support. Provider is an extension point that allows you to create a configurable module for any database/API. We are currently working on the provider for Sequelize ORM (supports PostgreSQL, MySQL, SQLite and MSSQL).

I don't fully grasp the idea of the forward request, so I've made a generic implementation that can be used to proxy requests to third-party systems.

You can test the implementation here: https://ftest.gft.network/federation/

Examples:

Resolve predefined account by name:
https://ftest.gft.network/federation/?q=gft-issuer-account*ftest.gft.network&type=name

You can create your own account, just provide username and accountid (Stellar address).

https://ftest.gft.network/federation/add/?username=johny&accountid=GCCYESWKD7CJU5SG7MFZ4DXN77MLNIGTVHDOF6PUPXE7VBRZGKTMGHCI
https://ftest.gft.network/federation/?q=johny*ftest.gft.network&type=name

The ftest.gft.network domain defines stellar.toml file that contains a reference to the test federation server. So it can be used to resolve names or create a trustline in wallets with Federation protocol support.

Any feedback is highly appreciated.

This will definitely come in handy to other devs, especially ones that don't use mysql, postgresql or sqlite for databases. If you can support the providers sacarlson mentioned, that will be great.
Let us know when we can test it out.
