How to Use MyGet to Manage and Distribute Packages
MyGet is a universal package manager that allows you to create custom package feeds for Python, Maven, NuGet, npm, Bower, PHP, Vsix, and Ruby Gems. For me, the most significant advantage of using MyGet is I can overwrite the package with the same version number comparing to other package repositories like PyPi and npmjs. This article shares how to upload Dynamsoft Barcode Reader packages to MyGet and how to install the packages for relevant projects.
Uploading Packages to MyGet
Create a MyGet account.
Sign in to MyGet and create a feed.
I created a feed for Dynamsoft packages.
The next step is to click ADD PACKAGE to upload relevant packages. I will upload packages for Maven, Python, NuGet, and NPM.
Maven
Upload the pom.xml and .jar files.
Python
Upload the .whl file.
NuGet
Upload the *.nupkg file.
NPM
I failed to upload a zip package when using NPM. Using command-line tool seems more convenient.
Click FEED DETAILS to get your npm feed URL.
Run the adduser command via command-line tool:
npm adduser --registry=https://www.myget.org/F/dynamsoft/npm/
Publish the package with the new registry:
npm publish --registry=https://www.myget.org/F/dynamsoft/npm/
Installing Dynamsoft Barcode Reader Packages from MyGet
Get the free trial license.
Maven
Create a Maven project and add the configuration to pom.xml:
<repositories>
<repository>
<id>dbr</id>
<url>https://www.myget.org/F/dynamsoft/maven/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>com.dynamsoft</groupId>
<artifactId>dbr</artifactId>
<version>7.2.2</version>
</dependency>
</dependencies>
Set the license:
BarcodeReader br = new BarcodeReader("DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ==");
Sample code:

TextResult[] results = br.decodeFile("../test.jpg", "");
if (results == null || results.length == 0) {
System.out.println("No barcode found");
}
else {

System.out.println(pszTemp);
int iIndex = 0;
for (TextResult result : results) {

System.out.println(pszTemp);

System.out.println(pszTemp);

System.out.println(pszTemp);
System.out.println();

}
} catch (BarcodeReaderException e) {
e.printStackTrace();
}
}
}
Python
Install dbr:
pip install –index-url https://www.myget.org/F/dynamsoft/python/ dbr
Set the license:
dbr.InitLicense(license)
Sample code:
from dbr import DynamsoftBarcodeReader
dbr = DynamsoftBarcodeReader()
def InitLicense(license):
dbr.InitLicense(license)
def DecodeFile(fileName):
try:
results = dbr.DecodeFile(fileName)
textResults = results["TextResults"]
resultsLength = len(textResults)
print("count: " + str(resultsLength))
if resultsLength != 0:
for textResult in textResults:
print(textResult["BarcodeFormatString"])
print(textResult["BarcodeText"])
localizationResult = textResult["LocalizationResult"]
x1 = localizationResult["X1"]
y1 = localizationResult["Y1"]
x2 = localizationResult["X2"]
y2 = localizationResult["Y2"]
x3 = localizationResult["X3"]
y3 = localizationResult["Y3"]
x4 = localizationResult["X4"]
y4 = localizationResult["Y4"]
localizationPoints = [(x1,y1),(x2,y2),(x3,y3),(x4,y4)]
print(localizationPoints)
else :
print("No barcode detected")
except Exception as err:
print(err)
if __name__ == "__main__":
#you can change the following three variables' value to your own value.
licenseKey = "Input your own license"
fileName = r"../test.jpg"
InitLicense(licenseKey)
DecodeFile(fileName)
NuGet
In Visual Studio 2017, add the package source https://www.myget.org/F/dynamsoft/api/v3/index.json.
Install the package to your .NET project.
Set the license:
mBarcodeReader = new BarcodeReader("DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ==");
Sample code:
pictureBox1.Image = bitmap;
textBox1.Clear();
this.Invoke((MethodInvoker)delegate
{
string[] results = mBarcodeReaderManager.ReadBarcode(bitmap);
if (results != null)
{
foreach (string result in results)
{
textBox1.AppendText(result);
textBox1.AppendText(Environment.NewLine);
}
}
else
{
textBox1.AppendText("No barcode detected!");
}
});
NPM
Install dynamsoft-javascript-barcode via the custom registry:
npm set registry https://www.myget.org/F/dynamsoft/npm/
npm install dynamsoft-javascript-barcode
Set the license:
Dynamsoft.DBR.BarcodeReader.license = "DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ==";
