Now that you know what is HTMLeer.dev we can learn how to use it.

API documeentation

You can find available options in our swagger documentation.

Usage of the API

It's really simple, all you need to do is call HTMLeer API with your API key. Here's an example how you can create and download pdf file using HTMLeer API (with a help of p-retry in case of any failures).

import pRetry, { AbortError } from 'p-retry';

const generatePDF = async () => {
    const response = await fetch('https://api.htmleer.dev/v1/generate/pdf', {
        method: 'POST',
        body: JSON.stringify({
            savePdf: false,
            filename: 'my-file',
            html: `<div>Hello {{ name }}!</div>`,
            arguments: { name: 'HTMLeer' },
            options: { format: 'A4' }
        }),
        headers: {
            'content-type': 'application/json',
            'api-key': process.env.HTMLEER_API_KEY
        },
    });

    // we are stopping retrying because its custom api error
    if (!response.ok && response.status < 500) {
        throw new AbortError(response.statusText);
    }

    if (!response.ok) {
        throw new Error(response.statusText);
    }

    return response.arrayBuffer();
};

try {
    const result = await pRetry(generatePDF, { retries: 5 });
    const blob = new Blob([result], { type: "application/pdf" });
    const objectUrl = URL.createObjectURL(blob);
    window.open(objectUrl);
} catch (err) {
    console.log(err);
}
