Features

GraphQL query abstraction and caching improving the performance of your app
SSR React wrapper, allowing you to cache in browser
Configurable caching options, giving you complete control over your cache
Fullstack integration, leveraging client-side and server-side caching to streamline your caching strategy
Support for the full GraphQL convention
Optional GraphQL DoS attack mitigation security module

Overview

Obsidian is Deno’s first native GraphQL caching client and server module. Boasting lightning-fast caching and fetching capabilities alongside headlining normalization and rebuilding strategies, Obsidian is equipped to support scalable, highly performant applications.

With additional support for use in server-side rendered React apps built with Deno, full stack integration of Obsidian enables a fast and flexible caching solution.

Installation

QUICK START

Creating the Router

import { Application, Router } from 'https://deno.land/x/oak@v6.0.1/mod.ts';
import { ObsidianRouter, gql } from 'https://deno.land/x/obsidian/mod.ts';
import { resolvers } from './ import from your resolvers file'
import { types } from './ import your schema/types from schema/types file'


interface ObsRouter extends Router {
  obsidianSchema?: any;
}

const GraphQLRouter = await ObsidianRouter<ObsRouter>({
  Router,
  typeDefs: types,
  resolvers: resolvers,   
  redisPort: 6379,        //Desired redis port
  useCache: true,         //Boolean to toggle all cache functionality
  usePlayground: true,    //Boolean to allow for graphQL playground
  useQueryCache: true,    //Boolean to toogle full query cache
  useRebuildCache: true,  //Boolean to toggle rebuilding from normalized data
  customIdentifier: ["id", "__typename"]  
        
});

// attach the graphql routers routes to our app
  app.use(GraphQLRouter.routes(), GraphQLRouter.allowedMethods());

Creating the Wrapper

import { ObsidianWrapper } from 'https://deno.land/x/obsidian/clientMod.ts';

const App = () => {
  return (
    <ObsidianWrapper>
      <MovieApp />
    </ObsidianWrapper>
  );
};

Making a Query

import { useObsidian, BrowserCache } from 'https://deno.land/x/obsidian/clientMod.ts';

const MovieApp = () => {
  const { query, cache, setCache } = useObsidian();
  const [movies, setMovies] = (React as any).useState('');

  const queryStr = `query {
      movies {
        id
        title
        releaseYear
        genre
      }
    }
  `;

  return (
    <h1>{movies}</h1>
    <button
      onClick={() => {
        query(queryStr)
        .then(resp => setMovies(resp.data))
        .then(resp => setCache(new BrowserCache(cache.storage)))
      }}
    >Get Movies</button>
  );
};

Making a Mutation

import { useObsidian, BrowserCache } from 'https://deno.land/x/obsidian/clientMod.ts';

const MovieApp = () => {
  const { mutate, cache, setCache } = useObsidian();
  const [movies, setMovies] = (React as any).useState('');

  const queryStr = `mutation {
    addMovie(input: {title: "Cruel Intentions", releaseYear: 1999, genre: "DRAMA" }) {
      id
      title
      releaseYear
      genre
    }
  }
  `;

  return (
    <h1>{movies}</h1>
    <button
      onClick={() => {
        mutate(queryStr)
        .then(resp => setMovies(resp.data))
        .then(resp => setCache(new BrowserCache(cache.storage)))
      }}
    >Get Movies</button>
  );
}
