http-link-dataloader

???????? HTTP Apollo Link with batching & caching provided by dataloader.

Idea

A Apollo Link that batches requests both in Node and the Browser. You may ask what's the difference to apollo-link-batch-http. Instead of having a time-frame/fixed cache size based batching approach like in apollo-link-batch-http, this library uses dataloader for batching requests. It is a more generic approach just depending on the Node.JS event loop that batches all consecutive queries directly. The main use-case for this library is the usage from a graphql-yoga server using prisma-binding, but it can be used in any environment, even the browser as the latest dataloader version also runs in browser environments.

Usage

1import { HTTPLinkDataloader } from 'http-link-dataloader'
2
3const link = new HTTPLinkDataloader()
4
5const token = 'Auth Token'
6
7const httpLink = new HTTPLinkDataloader({
8  uri: `api endpoint`,
9  headers: { Authorization: `Bearer ${token}` },
10})

Caching behavior

Note that the dataloader cache aggressively caches everything! That means if you don't want to cache anymore, just create a new instance of BatchedHTTPLink. A good fit for this is every incoming HTTP request in a server environment - on each new HTTP request a new BatchedHTTPLink instance is created.

Batching

This library uses array-based batching. Querying 2 queries like this creates the following payload:

1query {
2  Item(id: "1") {
3    id
4    name
5    text
6  }
7}

1query {
2  Item(id: "2") {
3    id
4    name
5    text
6  }
7}

Instead of sending 2 separate http requests, it gets combined into one:

1;[
2  {
3    query: `query {
4      Item(id: "1") {
5        id
6        name
7        text
8      }
9    }`,
10  },
11  {
12    query: `query {
13      Item(id: "2") {
14        id
15        name
16        text
17      }
18    }`,
19  },
20]

Note that the GraphQL Server needs to support the array-based batching! (Prisma supports this out of the box)

Even better batching

A batching that would even be faster is alias-based batching. Instead of creating the array described above, it would generate something like this:

1{
2  query: `
3    query {
4      item_1: Item(id: "1") {
5        id
6        name
7        text
8      }
9      item_2: Item(id: "2") {
10        id
11        name
12        text
13      }
14    }`
15}

This requires a lot more logic and resolution magic for aliases, but would be a lot faster than the array based batching as our tests have shown! Anyone intersted in working on this is more than welcome to do so! You can either create an issue or just reach out to us in slack and join our #contributors channel.
