Use in your application

const unoconv = require('unoconv-server');

const app = express();
app.use('/unoconv', unoconv());
// ... your own express routes
app.listen(3000);

Converter

When the server starts, it will start a listener for better performance, the listener will be stopped together with the server.

The server provides a similar interface like unoconv, you can simply remove -- or - and use / instead of white-space between the arguments, all after /convert.

POST /convert/format/<format>[/output/<filename>] HTTP/1.1

You can upload file by either of the following method:

• multipart/form-data upload with a file field of the file to be converted.
• RAW upload a file in HTTP body with Content-Type and Content-Disposition header provided.

If the /output/<value> option is provided, the Content-Disposition header will contain the new filename.

The converted document will be directly output from the HTTP response body.

Environment Variables

Name	Description
HOSTNAME	For server listening hostname
PORT	For server listening port

Example

Uploading with multipart/form-data

curl -F file=@example.docx http://127.0.0.1:4000/convert/format/pdf/output/newname.pdf > result.pdf

Uploading RAW binary data

curl -X POST \
-T "example.docx" \
