ReductStore Client SDK for JavaScript

The ReductStore Client SDK for JavaScript is an asynchronous HTTP client for interacting with a ReductStore instance from a JavaScript application. It is written in TypeScript and provides a set of APIs for accessing and manipulating data stored in ReductStore.

Features

• Promise-based API for easy asynchronous programming
• Support for ReductStore HTTP API v1.12
• Token-based authentication for secure access to the database
• Labeling for read-write operations and querying
• Batch operations for efficient data processing

Getting Started

To get started with the ReductStore Client SDK for JavaScript, you'll need to have ReductStore installed and running on your machine. You can find instructions for installing ReductStore here.

Once you have ReductStore up and running, you can install the ReductStore Client SDK for JavaScript using npm:

npm i reduct-js

Then, you can use the following example code to start interacting with your ReductStore database from your JavaScript application:

const { Client, QuotaType } = require("reduct-js");

// 1. Create a ReductStore client
const client = new Client("http://127.0.0.1:8383", {
  apiToken: "my-token",
});

// 2. Get or create a bucket with 1Gb quota
const bucket = await client.getOrCreateBucket("my-bucket", {
  quotaType: QuotaType.FIFO,
  quotaSize: BigInt(1e9),
});

// 3. Write some data with timestamps in the 'sensor-1' entry
const us = (dateString) => BigInt(Date.parse(dateString) * 1000);
let record = await bucket.beginWrite("sensor-1", us("2021-01-01T00:00:00Z"));
await record.write("Record #1");
record = await bucket.beginWrite("sensor-1", us("2021-01-01T00:00:01Z"));
await record.write("Record #2");

// 4. Query the data by time range
for await (const record of bucket.query(
  "sensor-1",
  us("2021-01-01T00:00:00Z"),
  us("2021-01-01T00:00:02Z"),
)) {
  console.log(`Record timestamp: ${record.timestamp}`);
  console.log(`Record size: ${record.size}`);
  console.log(await record.readAsString());
}
