@rawewhat/quera NPM

QueRa

is a simplified Firestore and GraphQL(soon) client built purely in React hooks.

Content

Install

using npm
npm i @rawewhat/quera

using yarn
yarn add @rawewhat/quera

Usage

just import useFirestore() hook in your React component.

import useFirestore from "@rawewhat/quera";

call useFirestore() hook to get subscribed data and CRUD handler functions

const [data, handler] = useFirestore(collectionPath, whereClause);

handlers include CRUD basic function like createDoc(), deleteDoc(), readDoc(), and updateDoc().
passing where clause to select only documents with specific value "?name == QueRa"

API

1. CRUD Operation

call useFirestore() hook to get CRUD handler functions.

const [, { createDoc, deleteDoc, readDoc, updateDoc }] = useFirestore();

NOTE
without passing path to useFirestore(path) hook,
all CRUD functions required collectionPath parameter!

1.1. createDoc(createData, collectionPath)

createData: object
collectionPath: string

createDoc({ name: "New Name" }, "user").then(doc => {
  console.log("doc.name =", doc.data.name);
});

const createdDoc = await createDoc({ name: "New Name" }, "user");
console.log("doc.name =", createdDoc.data.name);

Result: doc.name = New Name

1.2. deleteDoc(docId, collectionPath)

docId: string
collectionPath: string

deleteDoc("007", "user").then(doc => {
  console.log("doc 007", !doc.data ? "deleted" : "delete fail!");
});

const deletedDoc = await deleteDoc("007", "user");
console.log("doc 007", !deletedDoc.data ? "deleted" : "delete fail!");

Result: doc 007 deleted

1.3. readDoc(undefined, collectionPath)

passing undefined to get all documents in collection path

collectionPath: string

readDoc(undefined, "user").then(response => {
  response.data.forEach(doc => {
    console.log(`${doc.id}`, doc);
  });
});

const response = await readDoc(undefined, "user");
response.data.forEach(doc => {
  console.log(`doc ${doc.id} =`, doc);
});

Result: doc 007 = { name: New Name }

1.4. readDoc(docId, collectionPath)

docId: string
collectionPath: string

readDoc("007", "user").then(doc => {
  console.log("doc 007", doc);
});

const doc = await readDoc("007", "user");
console.log("doc 007 =", doc);

Result: doc 007 = { name: New Name }

1.5. readDoc(whereClause, collectionPath)

whereClause: string
collectionPath: string

readDoc("?name == New Name", "user").then(response => {
  response.data.forEach(doc => {
    console.log(`doc ${doc.id} =`, doc);
  });
});

const response = await readDoc("?name == New Name", "user");
response.data.forEach(doc => {
  console.log(`doc ${doc.id} =`, doc);
});

Result: doc 007 = { name: New Name }

1.6 updateDoc(docId, updateData, collectionPath)

docId: string
updateData: object
collectionPath: string

updateDoc('007', { name: 'Updated Name' }, 'user').then(doc => {
    console.log('doc 007 updated =', doc)
})

const updatedDoc = await updateDoc('007', { name: 'Updated Name' }, 'user')
console.log('doc 007 updated =', doc)

Result: doc 007 updated = { name: Updated Name }

2. Real-time Data Subscription

const [data, handlers] = useFirestore(collectionPath);

data: arrays
collectionPath: string
NOTE
passing path to useFirestore(path) hook will subscribe component to the collection path,
all CRUD functions will use collectionPath passed from useFirestore(path) hook. but you can still force to use collectionPath passing from CRUD function instead.

2.1 useFirestore(firestore, collectionPath)

firestore: object
collectionPath: string

const [data, handlers] = useFirestore(firestore, 'user')
console.log('subscribed data =', data)

2.2 useFirestore(firestore, collection_path, where_clause)

firestore: object
collectionPath: string
whereClause: string

const [data, handlers] = useFirestore(firestore, 'user', '?name == Updated Name')
console.log('subscribed data', data)

Example

import React, { useEffect } from "react";
import { useFirestore } from "@rawewhat/quera";

const _ = undefined;
const ID_TEST = "SbfOYDq77jG8N6v9N15k";
const CREATE_DATA_TEST = { name: "New Name" };

const HomeScreen = () => {
  const [{ data }, { createDoc, deleteDoc, readDoc, updateDoc }] = useFirestore(
    "delivery_telegram"
  );
  console.log("data", data);

  const handleClick = type => () => {
    switch (type) {
      case "create":
        return createDoc(CREATE_DATA_TEST, "delivery_telegram");
      case "delete":
        return deleteDoc(ID_TEST, "delivery_telegram");
      case "read":
        return readDoc(_, "delivery_telegram");
      case "read-by-id":
        return readDoc(ID_TEST, "delivery_telegram");
      case "read-by-query":
        return readDoc("?status == REQUESTED", "delivery_telegram");
      case "update":
        return updateDoc(ID_TEST, { status: "OPERATED" }, "delivery_telegram");
      case "update-requested":
        return updateDoc(ID_TEST, { status: "REQUESTED" }, "delivery_telegram");
      default:
    }
  };

  return (
    <div style={styles.container}>
      <h1>Test useFirestore</h1>
      <div style={styles.buttonContainer}>
        <h2>Create</h2>
        <Button title="Create" onClick={handleClick("create")} />
        <h2>Delete</h2>
        <Button title="Delete" onClick={handleClick("delete")} />
        <h2>Read</h2>
        <Button title="Read all doc" onClick={handleClick("read")} />
        <Button title="Read doc by id" onClick={handleClick("read-by-id")} />
        <Button
          title="Read doc by query"
          onClick={handleClick("read-by-query")}
        />
        <h2>Update</h2>
        <Button title="Update Operated" onClick={handleClick("update")} />
        <Button
          title="Update Requested"
          onClick={handleClick("update-requested")}
        />
      </div>
    </div>
  );
};

const Button = ({ title, children, onClick }) => {
  return (
    <button style={styles.button} onClick={onClick}>
      {children || title}
    </button>
  );
};

Demo

I wrote a simple site to test out QueRa functionality in the demo project.

git clone git@github.com:rawewhat/routra.git to clone the project
cd demo change to demo directory
yarn install to install dependencies
yarn dev it will be ready on http://localhost:1234
