Intro

Plantuml-js builds on top of deflate-js and adds the requirement in order consume plantuml API from Javascript. You can read more about here.

Usage

import fs from "fs";
import Axios from "axios";
const { plantuml } = require("plantuml-js");
...
const uml = `
			@startuml
			Class01 <|-- Class02
			Class03 *-- Class04
			Class05 o-- Class06
			Class07 .. Class08
			Class09 -- Class10
			@enduml`;
			
const url = plantuml.generateUrl(_data.extension, uml);
await this.downloadResource(url, 'path/filname');

...
async downloadResource(url: any, filepath: string) {
    const response = await Axios({
      url,
      method: "GET",
      responseType: "stream",
    });
    return new Promise((resolve, reject) => {
      response.data
        .pipe(fs.createWriteStream(filepath))
        .on("error", reject)
        .once("close", () => resolve(filepath));
    });
  }		

Deflate-js Intro

Does deflate compression/decompression in the browser and node.

This module is not meant to be run on node for any production code. The native version of deflate should be used instead because it is much faster. The main reason for this being node-compatible is for testing purposes.

Currently deflate does not pass all tests, but inflate does. This should not be used for compressing data yet in production.

Install

For node, deflate-js can be installed with npm: npm install deflate-js

For the browser, deflate-js can be installed with pakmanager.

API

Deflate:

deflate(arr[, level])

arr- Byte array to compress

level- 1-9 (compression level; optional)

Inflate:

inflate(arr)

arr- Byte array to decompress

The basic usage (no level) will suffice for most purposes.

Basic Usage

var deflate = require('deflate-js'),
	arr;

arr = Array.prototype.map.call('Hello world', function (char) {
	return char.charCodeAt(0);
});

// compress some text
var compressed = deflate.deflate(arr);

// decompress some text
var decompressed = deflate.inflate(compressed);
