What is Node.js and NPM?
Node.js is an entire platform for building server-side applications using the JavaScript programming language. Node.js is based on a modular system that allows you to add individual packages to your application.
Node.js uses the Node Package Manager (npm) to manage dependencies. This allows you to download and install modules required for the project from third-party sources.
TL;DR
- What is the motivation NEMTUS created @nemtus/symbol-sdk-typescript?
- The motivation was to use the equivalent functionality of symbol-sdk v3 implemented in JS in a TypeScript environment, stress-free and without any special settings.
- How @nemtus/symbol-sdk-typescript was created from symbol-sdk v3, implemented for JavaScript, into TypeScript in the simplest way?
- It was created by building from original symbol-sdk v3 using the following link’s way.
- For more information, please refer to the following links to the SDK repository and the npm (Node Package Manager) package.

Background
Symbol blockchain’s version 2 SDK for TypeScript/JavaScript has been deprecated, and the core development team is working on the development and maintenance of a version 3 SDK for JavaScript, which is easier to work with.
symbol-sdk v 2
symbol-sdk v2 is an SDK for JavaScript/TypeScript that made it very easy to develop with the Symbol blockchain using a rich feature set.
However, due to the differences in preferences regarding the rxjs used, the complexity of the rich functionality, and the organizational changes, the decision was made to create a new reference SDK that is more consistent with the core protocol. It has been officially announced that SDK v2 is deprecated.
symbol-sdk v 3
The new version of SDK 3 is written in JavaScript, so if you try to use it in a TypeScript environment, βModule ‘***’ or corresponding type declaration not found.β error will occur. In today’s front-end development environment, where the TypeScript programming language is very popular, the situation is not very good.
Therefore, in order to remedy this situation and try to somehow convert the SDK to a programming language in TypeScript, we have considered the following 3 methods:
- Fork the symbol-sdk v2 of the TypeScript SDK and continue to support (maintenance) independently of the NEMTUS developers and community developers.
- The Japanese organization NEMTUS and community developers will implement the TypeScript SDK and continue development and maintenance, referencing SDK version 3, for JavaScript.
- Fork version of SDK 3 for JavaScript used as is. Next, NEMTUS and developers from the Symbol community will add or automatically generate the required TypeScript “.d.ts” files to simplify development and maintenance.
__________
Options that we rejected:
- The repositories for important dependency packages were not open to the public, and maintaining them seemed difficult to me.
- It is necessary to have a precise understanding of how NEM/Symbol blockchain transactions are to be binarized and processed as a βDSLβ (Domain-Specific Language), so this is likely to take time and be a very complex factor.
We received advice from independent volunteer developers in the Symbol community and decided to go with method number 3, which is described earlier in this article.
Starting with the TypeScript programming language version 3.7 or later, you can create a “.d.ts” file (which describes the syntax and structure of functions and properties) from β.jsβ files. The JSDoc comments were relatively well written in the official SDK (Software Development Kit), so we were able to release an updated SDK that can be used to some extent in the TypeScript environment.
JSDoc comments are written to JavaScript source code and are used by authoring tools to provide developers with appropriate hints and additions, and to automatically generate documentation.
How to generate d.ts file from js file?

Example code for sending a transaction using @nemtus/symbol-sdk-typescript
Installation
- Install Node.js (If you have, then skip this step).
- Create an appropriate directory (symbol-sdk-typescript-sample-1 here as an example) and initialize.
<!-- wp:paragraph -->
<p>~/$ mkdir symbol-sdk-typescript-sample-1</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>~/$ cd symbol-sdk-typescript-sample-1</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>~/symbol-sdk-typescript-sample-1$ npm init -y</p>
<!-- /wp:paragraph -->Install required packages
In this example, we will use the following packages to send transactions:
- typescript, ts-node… The Typescript programming language is used to perform various actions, allowing (to more fully describe the properties and methods of objects and classes in Typescript), and ts-node is necessary for the convenience of performing these tasks.
- Using the REST API, you can get information about the Symbol blockchain, as well as implement sending transactions and much more.@nemtus/symbol-sdk-openapi-generator-typescript-axios
- The TypeScript Software Development Kit (SDK) created this time (handling account information, generating transaction data, signing, etc.). @nemtus/symbol-sdk-typescript
- To use web sockets. Ws
- To use the client’s REST API. Axios
- To treat the private key as an environment variable and not write the private key to the source code. dotenv
You need to run the following command:
~/symbol-sdk-typescript-sample-1$ npm install -D typescript ts-node @types/ws
~/symbol-sdk-typescript-sample-1$ npm install @nemtus/symbol-sdk-typescript @nemtus/symbol-sdk-openapi-generator-typescript-axios axios ws dotenv
Create a tsconfig.json file
Run the following command to generate a tsconfig.json configuration file template for compiling TypeScript code.
~/symbol-sdk-typescript-sample-1$ npx tsc –init
Change “target”: “es2016” to “target”: “esnext” so you can use newer JavaScript writing style like ES modules and BigInt
BigInt allows developers to have much better integer representation and data processing for further work with this data, and ES adds an official unified module system to JavaScript.
Creating a test account and setting an environment variable
Download the official Symbol blockchain wallet, create a test account in the test network and receive test tokens in the Symbol Faucet π
https://testnet.symbol.tools. Then save your private, public key, as well as your wallet address.
So let ‘s add the private key to the file .env as follows.
.env
SIGNER_1_PRIVATE_KEY =”PUT_YOUR_PRIVATE_KEY_HERE”
β οΈ In the blockchain, the private key has the most and only power to do anything with your crypto account. The private key provides access to and control over your crypto account and should be kept secret. If your private key is compromised, you will lose all your assets and confidential information in your account. This time, we will create a one-time account on the Symbol testnet and try to use the private key as a simple environment variable using dotenv.
The dotenv module parses the “.env” file and makes the variables set in it available from environment variables.

Let’s create the following file and run it with npx ts-node send-transfer-transaction.ts

<!-- /wp:paragraph -->Summary
Now that we have a TypeScript REST API client and a TypeScript npm package (to send transactions), we can start front-end development in the TypeScript environment using tools that match the concept of the new official SDK.
However, if you look at the sample code, there are places where problems can be avoided with some work-around ways. Therefore, there may be some parts of the code that can be improved by writing comments in JSDoc comments(They will help to improve the type definition files automatically generated.), so if I can, I wanna send the pull request to improve them directly to the new official Symbol SDK.
About a year and a half has passed since the launch of Symbol, but there is still a lot unknown about how the Symbol and NEM ecosystem will develop. Also, at the moment it is unknown what place in the Symbol ecosystem will be occupied by the SDK from NEMTUS. (Maybe there will be another SDK, better than this one and that would be great).
