Package Exports

hl7js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hl7js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    reader.read(buffer.toString(), function (err, hl7Data) {
        console.log(err);
        console.log(hl7Data);
    });

Reading With Grammar

reader.read(buffer, grammarExpression, callback)

fs.readFile(hl7_file_path, function (err, buffer) {

    reader.read(buffer.toString(), 'MSH PID [{OBR {OBX}}]', function (err, hl7Data, hl7Json) {
            console.log(err);

            if (!err) {
                var patientName = hl7Json['PID'][5]; /// Similar pattern: hl7Json['PID'].fields[5].value ==> For advanced usage
                console.log('ORU->Patient name: ', patientName);
            }
    });
});
