Planted

Overview:

The Planted project purpose is to assist users by collecting data from a variety of sensors ex. humidity, temperature, sunlight, and soil moister. This in hopes of helping users to keep their plants alive and thriving. Sensors send data to the server and the React Native app visualizes the data

Router:

router.post('/register', async (req, res) => {
    let userInfo = await readBody(req).then(data => JSON.parse(data))
    let { avatar, username, email, password } = userInfo
    let hash = await bcrypt.hash(password, 10);
    await db.query(`
            INSERT INTO users (
                username, email, passw, avatar
            )
            VALUES (
                    '${username}',
                    '${email}',
                    '${hash}',
                    '${avatar}'
            );`)
        .catch(err => console.log(err))
    let user = await findUserByEmail(db, email);
    let token = createToken(user);
    res.end(token);
})

router.post('/graphql', async (req, res) => {
    let { authorization: token } = req.headers;
    try {
        let payload = jwt.verify(token, signature);
        let userid = payload.userid;
        let query = await readBody(req)
        let results = await getResults(query, userid);
        res.send(results)
    } catch (err) {
        console.log("POST GRAPHQL - ERROR ####", err)
        res.status(401).end('Unauthorized')
    }
})

module.exports = router;

Examples of fetching data with graphql

fetch('https://planted-dc.herokuapp.com/graphql', {
	headers: {
	"authorization": token,
},
	method: 'POST',
	body: `
	query {
	  currentUser {
        user {
            username
            avatar
        }
        plantData {
            temp
            sun
            moist
            humidity
            created
        }
	  }
    }`
