Serialization & Deserialization

[kafechew]

I'm having issues with the Serialisation and Deserialisation for combination of limdu + serialization npm packages.

Normally, we will serialise into a .json file.
Using serialize.toString(), I don't where is the serialized .json file.

Q1. Maybe limdu/serialization will not generate the .json file?

Anyone can enlighten?
Thanks.

Hi Kai,

The function serialize.toString does not automatically generate a json file. It only returns a string.

To save the string to a file, you can use the standard writeFile or writeFileSync function of the fs library, see here:
https://nodejs.org/api/all.html#all_fs_writefile_filename_data_options_callback

For example:

var fs = require('fs');  
var classifierString = serialize.toString(intentClassifier, newClassifierFunction);
fs.writeFileSync("myFileName.json", classifierString);

You're so cool!

Let's say I had saved the string to "myFileName.json" as suggested...
and send into remote server folder, "/myFolder".
How to initialize the deserialization?

My guess:

var intentClassifierCopy = serialize.fromString(intentClassifierString, myFolder/myFileName.json);

Am I right?

Thanks again!

In order to deserialize, you first have to read the string from the file, like this:

var intentClassifierString = fs.readFileSync("myFolder/myFileName.json");
var intentClassifierCopy = serialize.fromString(intentClassifierString, __dirname);

Working great!
I had migrated from natural to limdu!
Thank you very much!

The above, we will store the .json files as local files in the remote server.
What if the .json file is an external file, not a local file?
Instead of moving the files to remote server, can the remote server directly call the .json from the original server?

Can we deserialise the external .json (http://anotherweb.com/json/myFileName.json) ?

My guess:

var __dirname = "http://anotherweb.com/json";
var intentClassifierString = fs.readFileSync("myFileName.json");
var intentClassifierCopy = serialize.fromString(intentClassifierString, __dirname);

Can you confirm that?
Thanks in advanced.

Hi Kai,

I think readFileSync works only with local files.

To download a remote file, try the suggestions here:

You're right. Just solved through alike method as you suggested, i.e. xhr
Things are interesting now!
Thanks again!! :-)
