mimosa NPM (How It Works For Developers)

In Node.js, minification means optimization of code by reducing the file size through compressing. Through this process, it enhances performance and shortens load times. Extraneous characters, like whitespaces, comments, and line breaks, will be eliminated. Variable names and function names are usually reduced in their size. Minification removes unimportant pre-compiled code and reduces the size of a document, thus making the JavaScript, CSS, and HTML files very effective and quicker to download. In this article, we are going to learn more about Mimosa and its usage with the IronPDF module.

Introduction

Mimosa is an all-purpose NPM package published almost nine years ago that extends front-end development workflows through the use of powerful modules and functionality. Run commands like mimosa watch and build to automate the compilation of your code, and switch on reload for changes to be reflected in the browser instantly. This package has a config for efficiently customizing the build process and handling dependencies. For more information regarding mimosa see NPM documentation.

From the very first releases years ago, Mimosa moved on, and this new version supports pre-compiled and compiled JavaScript files much better. It only takes a simple installation, configuration of the mimosa settings for the project, and running a mimosa watch to start developing. You are highly encouraged to check out its very detailed documentation on how to use Mimosa, what it does, and how to set up the project's Mimosa config if you need more elaborate details.

It has a modular architecture and thus integrates easily with a wide array of plugins and extensions, adapting to different workflows and technologies. Also, Mimosa's flexible configuration supports any diversity in front-end tools and frameworks, really being an asset in modern web development. On the whole, Mimosa is a full solution for productivity enhancement and ease of development. It is powered by a strong community that moves forward with the evolution of developers' needs.

First, make sure you have Node.js and NPM installed in your system. Then, install Mimosa globally or locally in your project:

# Install Mimosa globally
npm install -g mimosa

# Install Mimosa globally
npm install -g mimosa

#Install Mimosa globally

Config Mimosa

exports.config = {
  "modules": [
    "copy",
    "server",
    "jshint",
    "csslint",
    "require",
    "minify-js",
    "minify-css",
    "live-reload",
    "bower"
  ],
  "server": {
    "views": {
      "compileWith": "html",
      "extension": "html"
    }
  }
}

exports.config = {
  "modules": [
    "copy",
    "server",
    "jshint",
    "csslint",
    "require",
    "minify-js",
    "minify-css",
    "live-reload",
    "bower"
  ],
  "server": {
    "views": {
      "compileWith": "html",
      "extension": "html"
    }
  }
}

exports.config = {
	"modules": ("copy", "server", "jshint", "csslint", "require", "minify-js", "minify-css", "live-reload", "bower"), "server": {
		"views": { "compileWith": "html", "extension": "html" }
	}
}

A mimosa-config.js, a configuration file name for the Mimosa build system configuring several facets of front-end development. A suite of modules enables copy, for file management; server, to set up a local development server; jshint and csslint, for the linting of JavaScript and CSS files respectively; minify-js and minify-css, to compress JavaScript and CSS files for improved performance.

Besides, it has live reload on browser refreshing due to code changes and bower for front-end dependencies. Configuration also ensures the view templates are compiled as .html files so that HTML views may be properly handled in development. The result of that is a complete configuration with asset management, optimization of source code, and improvement of workflow.

Start Mimosa Watch

Finally, once you have got your Mimosa settings set up, launch the watch process and it will automatically recompile your files any time they change:

mimosa watch

mimosa watch

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'mimosa watch

It watches your source files, recompiling them when necessary, and then with LiveReload, it quickly refreshes the changes in the browser.

Create PDF Generation script with IronPDF

Below is a Node.js script to generate PDFs using IronPDF. For instance, create generatePdf.js:

const IronPdf = require('@ironsoftware/ironpdf');
const { PdfDocument } = IronPdf;
// Set IronPDF configuration
const config = IronPdf.IronPdfGlobalConfig;
config.setConfig({ licenseKey: 'YOUR_LICENSE_KEY' }); // Replace with your actual license key
async function generatePDF(title, content) {
  try {
    // Generate PDF from HTML content
    const pdf = await PdfDocument.fromHtml(`<html><body><h1>${title}</h1><p>${content}</p></body></html>`);
    return await pdf.saveAsBuffer();
  } catch (error) {
    console.error('Error generating PDF:', error);
    throw error;
  }
}
module.exports = generatePDF;

const IronPdf = require('@ironsoftware/ironpdf');
const { PdfDocument } = IronPdf;
// Set IronPDF configuration
const config = IronPdf.IronPdfGlobalConfig;
config.setConfig({ licenseKey: 'YOUR_LICENSE_KEY' }); // Replace with your actual license key
async function generatePDF(title, content) {
  try {
    // Generate PDF from HTML content
    const pdf = await PdfDocument.fromHtml(`<html><body><h1>${title}</h1><p>${content}</p></body></html>`);
    return await pdf.saveAsBuffer();
  } catch (error) {
    console.error('Error generating PDF:', error);
    throw error;
  }
}
module.exports = generatePDF;

Private const IronPdf = require( '@ironsoftware/ironpdf');
'INSTANT VB TODO TASK: The following line could not be converted:
const
	Private PdfDocument } = IronPdf
' Set IronPDF configuration
Private const config = IronPdf.IronPdfGlobalConfig
config.setConfig({ licenseKey: 'YOUR_LICENSE_KEY' }); ' Replace with your actual license key
'INSTANT VB TODO TASK: Local functions are not converted by Instant VB:
'async @function generatePDF(title, content)
'{
'  try
'  {
'	' Generate PDF from HTML content
'	const pdf = await PdfDocument.fromHtml(`<html><body><h1> ${title}</h1><p> ${content}</p></body></html>`);
'	Return await pdf.saveAsBuffer();
'  }
'  catch (@error)
'  {
'	console.@error('@Error generating PDF:', @error);
'	throw @error;
'  }
'}
[module].exports = AddressOf generatePDF

Replace 'YOUR_LICENSE_KEY' with your actual IronPDF license key.

Integrate Mimosa and IronPDF in an Express.js App

Integrate Mimosa for asset management and IronPDF for generating PDFs in an Express.js application:

const express = require('express');
const bodyParser = require('body-parser');
const generatePDF = require('./generatePdf'); // Path to your PDF generation script
const app = express();
app.use(bodyParser.json());
// Serve assets managed by Mimosa
app.use(express.static('public'));
// Route to generate PDF
app.post('/generate-pdf', async (req, res) => {
  const { title, content } = req.body;
  if (!title || !content) {
    return res.status(400).json({ error: 'Title and content are required' });
  }
  try {
    // Generate PDF
    const pdfBuffer = await generatePDF(title, content);
    // Respond with the PDF
    res.set({
      'Content-Type': 'application/pdf',
      'Content-Disposition': 'attachment; filename="generated.pdf"'
    });
    res.send(pdfBuffer);
  } catch (error) {
    console.error('Error generating PDF:', error);
    res.status(500).json({ error: 'Failed to generate PDF' });
  }
});
// Start listening
app.listen(3000, () => {
  console.log('Server running on http://localhost:3000');
});

const express = require('express');
const bodyParser = require('body-parser');
const generatePDF = require('./generatePdf'); // Path to your PDF generation script
const app = express();
app.use(bodyParser.json());
// Serve assets managed by Mimosa
app.use(express.static('public'));
// Route to generate PDF
app.post('/generate-pdf', async (req, res) => {
  const { title, content } = req.body;
  if (!title || !content) {
    return res.status(400).json({ error: 'Title and content are required' });
  }
  try {
    // Generate PDF
    const pdfBuffer = await generatePDF(title, content);
    // Respond with the PDF
    res.set({
      'Content-Type': 'application/pdf',
      'Content-Disposition': 'attachment; filename="generated.pdf"'
    });
    res.send(pdfBuffer);
  } catch (error) {
    console.error('Error generating PDF:', error);
    res.status(500).json({ error: 'Failed to generate PDF' });
  }
});
// Start listening
app.listen(3000, () => {
  console.log('Server running on http://localhost:3000');
});

Private const express = require( 'express');
Private const bodyParser = require( 'body-parser');
Private const generatePDF = require( './generatePdf'); ' Path to your PDF generation script
Private const app = express()
app.use(bodyParser.json())
' Serve assets managed by Mimosa
app.use(express.static( 'public'));
' Route to generate PDF
app.post( '/generate-pdf', async(req, res) =>
If True Then
'INSTANT VB TODO TASK: The following line could not be converted:
	const
	If True Then
		title, content } = req.body
		If Not title OrElse Not content Then
			Return res.status(400).json({ [error]: 'Title @and content are required' });
		End If
		Try
			const pdfBuffer = Await generatePDF(title, content)
			res.set({ 'Content-Type': 'application/pdf', 'Content-Disposition': 'attachment; filename="generated.pdf"' });
			res.send(pdfBuffer)
		Catch e1 As [error]
			console.error( '@Error generating PDF:', @error);
			res.status(500).json({ [error]: 'Failed @to generate PDF' });
		End Try
	End If
	)

'app.listen(3000, () => { console.log('Server running on http: });

Defines a route with the POST method that is handled for the /pdf request. Extracts title and content from the request body and verifies if they exist. Otherwise, in case any of these fields are missing, it will return a status 400 with an error message. Otherwise, it will attempt to generate a PDF by invoking generatePDF and by providing data to create a PDF.

In the case of success, this will establish a response header indicating the response content as a PDF file and append a filename for downloading. Then it will return the created PDF as a response. If generating a PDF fails, it logs the error and responds with 500 status and an error message.

Lastly, it is going to listen on port 3000 and log in to the console with a message saying that the server is running and is available at http://localhost:3000. Below is the screenshot of the PDF generated from the Mimosa module using the Postman tool.
