Usage

Go Package

Usage of the CFDI conversion library is quite straight forward. You must first have a GOBL Envelope including an invoice for Mexico ready to convert. There are some samples here in the test/data directory.

package main

import (
    "os"

    "github.com/invopop/gobl"
    "github.com/invopop/gobl.cfdi"
)

func main {
    data, _ := os.ReadFile("./test/data/invoice.json")

    env := new(gobl.Envelope)
    if err := json.Unmarshal(data, env); err != nil {
        panic(err)
    }

    // Prepare the CFDI document
    doc, err := cfdi.NewDocument(env)
    if err != nil {
        panic(err)
    }

    // Create the XML output
    out, err := doc.Bytes()
    if err != nil {
        panic(err)
    }

    // TODO: do something with the output
}
Testing

This package uses lestrrat-go/libxml2 for testing purporses, which in turn depends on the libxml-2.0 C library. Ensure you have the development dependency installed. In linux this implies:

sudo apt-get install libxml2-dev

Tests can take a while to run as they download the complete XML documents to test against, please be patient.

Command Line

The GOBL to CFDI tool also includes a command line helper. You can find pre-built gobl.cfdi binaries in the github repository, or install manually in your Go environment with:

go install github.com/invopop/gobl.cfdi

Usage is very straightforward:

gobl.cfdi convert ./test/data/invoice.json

Which should produce something like:
