Integration

Project config.

// imports/passport.ts
import { applyPassport } from '@deepcase/auth/passport/index';
import github from '@deepcase/auth/passport/github';
import LocalStrategy from 'passport-local';
import Debug from 'debug';

const debug = Debug('deepcase:passport');

export const initPassport = () => applyPassport((passport) => {
  passport.use(github);

  passport.use(new LocalStrategy((username, password, done) => {
    debug('LocalStrategy', { username, password });
    if (username === 'abc' && password === 'abc') done(null, { id: 'abc' });
    else done(null, false);
  }));

  passport.serializeUser((user, done) => {
    debug('serializeUser', user);
    done(null, { id: user.id });
  });

  passport.deserializeUser((id, done) => {
    debug('deserializeUser', id);
    done(null, { id });
  });
});

App session context wrapper.

// pages/_app.tsx
import App from 'next/app';
import React from 'react';
import withAuth, { IAuth } from '@deepcase/auth';

class MyApp extends App {
  render() {
    const { Component, pageProps } = this.props;
    return <Component {...pageProps} />;
  }
}

export default withAuth(MyApp, {
  // optional handlers (default already defined)

  // redirect if no user
  handleUser: (user: IAuth, ctx) => {
    if (!user) redirectToLogin(ctx.ctx, process.env.AUTH_LOGIN);
  },
  // redirect if no session
  handleSession: (session: any, ctx) => {
    if (!session) {
      redirectToLogin(ctx.ctx);
      return Promise.resolve({
        pageProps: null,
        session: (null as unknown) as IAuth,
      });
    }
  },
});

Request route.

// pages/[provider].ts
import { withPassport } from '@deepcase/auth/passport';
import { Handler } from '@deepcase/auth/handler';
import { initPassport } from '../../../imports/passport';

initPassport();
export default withPassport(Handler());

Callback route.

// pages/callback/[provider].ts
import { withPassport } from '@deepcase/auth/passport';
import { Handler } from '@deepcase/auth/handler';
import { initPassport } from '../../../../imports/passport';

initPassport();
export default withPassport(Handler({
  failureRedirect: '/auth',
  successRedirect: '/',
}));

Page with auth.

// pages/index.tsx
import React from 'react';
import { useAuth } from '@deepcase/auth';

export default function Page() {
  const auth = useAuth();
  return <>
    <div>auth</div>
    <div><a href="/api/auth/logout">logout</a></div>
    <div><a href="/api/auth/github">github</a></div>
    <div><a href="/api/auth/local?username=abc&password=abc">local abc:abc</a></div>
    <div><a href="/api/auth/local?username=qwe&password=qwe">local qwe:qwe</a></div>
    <div>
      <pre><code>
        {JSON.stringify(auth?.result)}
      </code></pre>
    </div>
  </>;
}

Hasura Remote Schema with secure codes

// pages/api/hrs.ts
import { ApolloServer, gql } from 'apollo-server-micro';
import Cors from 'micro-cors';
import Debug from 'debug';
import isInteger from 'lodash/isInteger';
import { Handler } from '@deepcase/auth/hrs';
import random from 'lodash/random';

const debug = Debug('deepcase:auth:hrs');

const codesHash = {};

const { config, handler } = Handler({
  local: async ({ username, password }) => {
    debug('local', { username });
    if (username === 'abc' && password === 'abc') {
      return { id: 'abc', token: 'abc' };
    }
    return { error: '!user' };
  },
  sendCode: ({ address }) => {
    const code = `${random(0, 9)}${random(0, 9)}${random(0, 9)}${random(0, 9)}`;
    const id = Math.random().toString(36).slice(2);
    codesHash[id] = code;
    console.log({ address, id, code });
    return { id };
  },
  checkCode: ({ sendId, code }) => {
    if (!codesHash[sendId]) {
      return { error: '!id' };
    }
    if (codesHash[sendId] === code) {
      return { id: 'abc', token: 'abc' };
    } else {
      return { error: '!code' };
    }
  },
});

export { config };
export default handler;
