Setup & Usage

Deno

https://jsr.io/@ndaidong/txtgen

deno add @ndaidong/txtgen

# npm (use any of npx, yarn dlx, pnpm dlx, or bunx)
npx jsr add @ndaidong/txtgen

import { sentence } from "@ndaidong/txtgen";

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}

You can use JSR packages without an install step using jsr: specifiers:

import { sentence } from "jsr:@ndaidong/txtgen";

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}

You can also use npm: specifiers as before:

import { sentence } from "npm:@ndaidong/txtgen";

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}

Or import from esm.sh

import { sentence } from "https://esm.sh/@ndaidong/txtgen";

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}

Node.js & Bun

https://www.npmjs.com/package/@ndaidong/txtgen

npm i @ndaidong/txtgen
# pnpm
pnpm i @ndaidong/txtgen
# yarn
yarn add @ndaidong/txtgen
# bun
bun add @ndaidong/txtgen

import { sentence } from "@ndaidong/txtgen";

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}

You can also use CJS style:

const { sentence } = require("@ndaidong/txtgen");

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}

Browsers:

<script type="module">
import { sentence } from "https://esm.sh/@ndaidong/txtgen";
// import { sentence } from 'https://unpkg.com/@ndaidong/txtgen/esm/mod.js';

for (let i = 0; i < 5; i++) {
  console.log(sentence());
}
</script>

APIs

• .sentence()
• .paragraph([Number totalSentences])
• .article([Number totalParagraphs])
• .addNouns(Array nouns)
• .addAdjectives(Array adjectives)
• .addTemplates(Array sentenceTemplates)
• .setNouns(Array nouns)
• .setAdjectives(Array adjectives)
• .setTemplates(Array sentenceTemplates)
• .getNouns()
• .getAdjectives()
• .getTemplates()
• .lorem([Number min [, Number max]])

As their name suggests, we have 4 groups of methods:

• sentence(), paragraph(), article(): generate text by given grammatical unit
• addNouns(), addAdjectives(), addTemplates(): add more samples to current sample set
• setNouns(), setAdjectives(), setTemplates(): replace current sample set with new ones
• getNouns(), getAdjectives(), getTemplates(): get current sample set

The set* and get* methods were added in v2.2.3 to help you customize your sample data.

In addition, we've added lorem() method since v3.0.5 to generate lorem ipsum text.

Template

If you want to add more kinds of sentences, just use the .addTemplates() method; it expects a list of sentence templates. Each sentence template is an English sentence, containing placeholders that can be replaced with any alternative word.

For example:

import { addTemplates } from "@ndaidong/txtgen";

const templates = [
  "{{a_noun}} is {{a_noun}} from the right perspective",
  "the {{noun}} of {{a_noun}} becomes {{an_adjective}} {{noun}}",
];

addTemplates(templates);

Here are the available placeholders:

• noun
• nouns
• a_noun
• adjective
• an_adjective

Lorem ipsum

Syntax:

lorem() // generate a random phrase with length from 2 to 24 words of lorem ipsum
lorem(Number min) // set the minimum number of words
lorem(Number min, Number max)// set the minimum/maximum number of words

Example:

import { lorem } from "@ndaidong/txtgen";

const phrase = lorem();
console.log(phrase); // => nisi blandit feugiat tempus imperdiet etiam eu mus augue

Development

Since v4.x.x, we switched to Deno platform, and use DNT to build Node.js packages.

git clone https://github.com/ndaidong/txtgen.git
cd txtgen

# test
deno test

# build npm packages
deno task build

cd npm
node test_runner.js
