Apollo Nested Comments Thread

[SachaG]

🤔 What you will need to know

Meteor, React, Apollo, and GraphQL.

🎯 The Goal

Recreate Telescope's Reddit-style nested comment threads with Apollo.

There are basically two approaches:

1. Load all of a post's comments and nest them on the client.
2. Perform the nesting in GraphQL and only load the first three levels of nesting (better).

📋 Step by Step

Some insights from @helfer:

let me think for a second about the nested comments.

depending on how you want to represent that nesting, and what you want to show at the beginning (before having expanded anything), I think you’ll want different ways of loading it on the server.

the most straightforward way in the GraphQL schema would be to give each comment a nested_comments field, and then just fetch those documents with a resolver.

then the fetchMore could simply use a query that accesses more comments from that particular document.

if you want to load everything at once, you could do that as well (with a special loader), but still access them in a nested fashion.

I guess I’d need some more specifics to know what the best way is. But there’s definitely a lot of possibilities with GraphQL, and they can be made efficient as well
