Getting Started

Using public URLs

const ILovePDFApi = require('@ilovepdf/ilovepdf-nodejs');

const instance = new ILovePDFApi('<PUBLIC_KEY>', '<SECRET_KEY>');

// Public and secret key can be found in your developer panel
// at https://developer.ilovepdf.com/user/projects .
const task = instance.newTask('merge');

// Promise-based way to use ILovePDFApi.
task.start()
.then(() => {
    return task.addFile('<FILE_URL>');
})
.then(() => {
    return task.addFile('<FILE_URL>');
})
.then(() => {
    return task.process();
})
.then(() => {
    return task.download();
})
.then((data) => {
    console.log('DONE');
});

Using ILovePDFFile class

const ILovePDFApi = require('@ilovepdf/ilovepdf-nodejs');
const ILovePDFFile = require('@ilovepdf/ilovepdf-nodejs/ILovePDFFile');

const instance = new ILovePDFApi('<PUBLIC_KEY>', '<SECRET_KEY>');

const task = instance.newTask('merge');

task.start()
.then(() => {
    const file = new ILovePDFFile('<FILE_PATH>');

    return task.addFile(file);
})
.then(() => {
    return task.addFile('<FILE_URL>');
})
.then(() => {
    return task.process();
})
.then(() => {
    return task.download();
})
.then((data) => {
    console.log('DONE');
});

Use sync calls

Thanks to be a promise-based API it is possible use the await JavaScript operator in order to call Task methods. Here you have an example:

    let task = instance.newTask('merge');
    await task.start();
    await task.addFile('<FILE_URL>');
    await task.addFile('<FILE_URL>');
    await task.process();

    const data = await task.download();

Get PDF information

On upload a file from a local file or URL, you will have access to some PDF information:

const ILovePDFApi = require('@ilovepdf/ilovepdf-nodejs');
const ILovePDFFile = require('@ilovepdf/ilovepdf-nodejs/ILovePDFFile');

const instance = new ILovePDFApi('<PUBLIC_KEY>', '<SECRET_KEY>');

const task = instance.newTask('merge');

task.start()
.then(() => {
    const file = new ILovePDFFile('<FILE_PATH>');

    return task.addFile(file);
})
.then(file1 => {
    // Access to PDF information.
    // file1.pageNumber
    // file1.pageSizes

    // File from URL.
    return task.addFile('<FILE_URL>');
})
.then(file2 => {
    // Access to PDF information.
    // file2.pageNumber
    // file2.pageSizes
});

Get remaining files

Due to this library is limited by number of uses, you can access to the account remaining files:

const task = instance.newTask('merge');
await task.start();
// After start a task, you can access to the remaining files quantity.
// Before, it's `undefined`.
console.log( task.remainingFiles )
