# Bigger Applications - Multiple Files

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

/// info

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure

Let's say you have a file structure like this:

```

    public void activateBatchMode(boolean ciEnv, String[] cliArgs, boolean isBatchMode) throws Exception {
        CliRequest request = new CliRequest(cliArgs, null);
        if (ciEnv) request.getSystemProperties().put("env.CI", "true");
        cli.cli(request);

        boolean batchMode = !cli.populateRequest(request).isInteractiveMode();

        assertThat(batchMode, is(isBatchMode));
    }

	dec := s2DecPool.Get().(*s2.Reader)
	dec.Reset(r)
	mr := msgpNewReader(dec)
	return &metacacheReader{
		mr: mr,
		closer: func() {
			dec.Reset(nil)
			s2DecPool.Put(dec)
			readMsgpReaderPoolPut(mr)
		},
		creator: func() error {
			v, err := mr.ReadByte()
			if err != nil {
				return err
			}
			switch v {
			case 1, 2:
			default:

     * reset.
     *
     * @return the array of bytes for the resulting hash value.

        int padLen = (bufferNdx < 56) ? (56 - bufferNdx) : (120 - bufferNdx);
