Dear team,
I want to implement the function of uploading an .xml or .bpmn file and this should then been depicted as the BPMN-Model. How can I do that? I mean I want this option (see picture) but I cannot implement/see it.
Simply implement a file upload and import the file using modeler.importXML
.
Thank you for answering
I was not able to achieve it just with “modeler.importXML”. Somehow the “Walktrough” is not as simple/easy as it is shown
This was my solution.
In app.js I added:
const multer = require('multer');
// Configure multer for file uploads
const upload = multer({ dest: 'uploads/' });
// Serve files from the uploads directory
app.use('/uploads', express.static(path.join(__dirname, 'uploads')));
// Route to handle file upload
app.post('/upload', upload.single('diagram'), (req, res) => {
// Respond with the path of the uploaded file
res.json({ file: `/uploads/${req.file.filename}` });
});
In index.js I added:
// Function to initialize the modeler and import the BPMN XML
function initializeModeler() {
const modeler = new BpmnModeler({
container: '#canvas'
});
// Attach this modeler instance to the window so it can be accessed globally
window.modeler = modeler;
}
// Function to import XML into the modeler
window.importXML = async (xml) => {
try {
await window.modeler.importXML(xml);
window.modeler.get('canvas').zoom('fit-viewport');
} catch (err) {
console.error('Error importing XML: ', err);
}
};
// Initialize the modeler when the script is loaded
initializeModeler();
In my website.ejs I added:
document.getElementById('uploadForm').addEventListener('submit', async function(event) {
event.preventDefault();
const formData = new FormData(this);
const response = await fetch('/upload', {
method: 'POST',
body: formData
});
const result = await response.json();
// Assuming `importXML` is a function exposed by your `bundle.js`
const xmlResponse = await fetch(result.file);
const xmlText = await xmlResponse.text();
window.importXML(xmlText);
});
