### Generate a TypeScript Client with Tags { #generate-a-typescript-client-with-tags }

If you generate a client for a FastAPI app using tags, it will normally also separate the client code based on the tags.

This way, you will be able to have things ordered and grouped correctly for the client code:

<img src="/img/tutorial/generate-clients/image06.png">

In this case, you have:

First, write all your **FastAPI** application as normally:

{* ../../docs_src/extending_openapi/tutorial001.py hl[1,4,7:9] *}

### Generate the OpenAPI schema { #generate-the-openapi-schema }

Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:

{* ../../docs_src/extending_openapi/tutorial001.py hl[2,15:21] *}

        try {
            assertTrue(outputFile.exists());
            generator.setCommandList(Collections.singletonList("invalid_command_for_test"));
            assertTrue(generator.generate("test_id", outputFile));
        } finally {
            outputFile.delete();
        }
    }

    public void test_generate_outputFile_null() throws Exception {
        generator.setCommandList(Collections.singletonList("echo test"));
        try {

	var buffer bytes.Buffer
	// data to be written into buffer.
	data := "1234567890"
	// seed the random number generator once.
	rand.Seed(3)
	// generate a random number between 13 and 200.
	randInt := getRandomRange(13, 200, -1)
	// write into buffer till length of the buffer is greater than the generated random number.
	for i := 0; i <= randInt; i += 10 {
		buffer.WriteString(data)
	}

	// create bucket.
	err = obj.MakeBucket(b.Context(), bucket, MakeBucketOptions{})
	if err != nil {
		b.Fatal(err)
	}

	// get text data generated for number of bytes equal to object size.
	textData := generateBytesData(objSize)
	// generate md5sum for the generated data.
	// md5sum of the data to written is required as input for PutObject.

	md5hex := getMD5Hash(textData)
	sha256hex := ""
