SimbaTS

TypeScript SDK for SIMBA Chain

@simbachain/simbats

SimbaTS is the TypeScript SDK for SIMBA Chain. It contains functionality for interacting with the SIMBA platform in general, as well as for interacting with your deployed smart contracts in particular. We currently have a service, Polyglot, that is under construction, which will streamline the process of interacting with your deployed smart contracts If you are using SimbaTS to interact with your deployed smart contracts, then we highly recommend you integrate with our Polyglot service, which we explain in this documentation. As of this writing (March 2023), Polyglot is still under construction.

Installation

To install using NPM:

npm install @simbachain/simbats

To clone:

git clone https://github.com/SIMBAChain/SimbaTS.git

Then you'll want to checkout the develop branch

Configuration and Authentication

Authentication in SimbaTS uses a client credentials flow. So to use SimbaTS, you'll need to first obtain client credentials from SIMBA Chain. To do so, go to the SIMBA Chain UI, and navigate to your organisation, then your application. Then, in the upper right hand side of the UI, you will see a "Secrets" button. If you click that button, you can create a client ID and client secret. Once you have obtained your client credentials, you will need to store them, along with a couple other environment variables. Here, we will explain what those variables are, and where to store them.

Environment variables you'll need to store

The environment variables you will need to store, with example values, are (keep reading for WHERE to store these variables):

SIMBA_API_BASE_URL="https://simba-dev-api.platform.simbachain.com/"
SIMBA_AUTH_BASE_URL="https://simba-dev-api.platform.simbachain.com/"
SIMBA_AUTH_CLIENT_ID="your SIMBA client ID"
SIMBA_AUTH_CLIENT_SECRET="your SIMBA client secret"

Additionally, you can also set the log level for debugging purposes. So for instance, if you want to set the SimbaTS logger to debug, you would set:

SIMBA_LOG_LEVEL="info"

Where to store your environment variables

We try to make sure that when you switch between different SIMBA Chain products, we make things as easy as possible for you. To aid in that, all SIMBA Chain SDKs use the same base environment variables, and look for them in a series of the same places. First, we provide a note on the SIMBA_HOME system level environment variable:

SIMBA_HOME

To help developers easily switch between all SIMBA SDKs, they can keep one .env file (name either .simbachain.env, simbachain.env, or .env) in a directory of their choice. Whatever directory they store this .env file in, the user can set the path to that directory as a system level environment variabale called SIMBA_HOME. If you don't set SIMBA_HOME, then it defaults to your home directory. So for instance, if you use .bash_profile for your system environment variables, then in your .bash_profile, you can set:

... rest of .bash_profile

export SIMBA_HOME=myexamplehomedirectory/dev/simbachain/mysimbahome/

Where, and in what order, we search for SIMBA environment files

For env vars, we search, in this order: * local project directory (the root of your project) for: - .simbachain.env - simbachain.env - .env

 * then we look for a SIMBA_HOME env var at the system level, and within that directory, we search for:
    - .simbachain.env
    - simbachain.env
    - .env

So if you are using multiple SIMBA products, then it's probably a good idea to set SIMBA_HOME as a system environment variable. If you're only using SimbaTS, then it's probably easier to create a .simbachain.env file in the top level of your project, and stick your environment variables in there, as instructed above.

authconfig.json

The way SimbaTS tracks access tokens is through the file authconfig.json. YOU DO NOT NEED TO CREATE THIS FILE. It automatically gets created once SimbaTS code retrieves an access token. Because access tokens are stored in this file, you should add it to your .gitignore:

... rest of .gitignore

# authconfig.json
**authconfig.json

Once all of this is configured, you're ready to start using SimbaTS!

Usage

There are a few main objects that you'll want to use in your project:

Simba
- Simba objects handle general interaction with the platform
- Simba objects can also be used to submit, call, and query methods of your deployed smart contracts
SimbaContract
- SimbaContract objects are used specifically to interact with your deployed smart contracts
- SIMBA Chain contract method endopints are "async" by default. This term is overloaded here; what "async" means here is that hitting a default contract method, a response will be returned without waiting for additional details about the transaction
SimbaSync
- SimbaSync is idential to Simba, except the contract object it instantiates through .getSimbaContract is an instance of SimbaContractSync instead of SimbaContract
SimbaContractSync
- SimbaContractSync is identical to SimbaContract, except it hits contract method endpoints synchronously instead of asynchronously. That that means in this context is that contract method requests made using SimbaContractSync will call /sync/ endpoints for contract methods, which means that the response will not return immediately, but will return with more information on the transaction when it does return.

The following sections provide examples of using the above objects, but we're also going to provide some example variables that are used throughout the examples, so that you can reference them when you see them in example method calls. So when you see a method call use the argument baseApiUrl, but you don't see it defined locally, know that it was defined previously, in the following variables, below.

quick note on "contractName" parameter:

A quick note on areas where you see the parameter "contractName" referenced. In most cases, "contractName" actually refers to the contract API name you specified when deploying your contract. So if you deployed a contract that, in its solidity code was called TestContract, and you deployed it using the API name "test_contract_v2", then this API name is actually what's being asked for where params are called "contractName".

SimbaContract

A note on the use of the "validateParams" parameter in SimbaContract.submitMethod. To prevent users from having to wait for an API call before they are informed that there is something wrong with one of their parameters, in terms of what the API expects, SimbaContract validates parameters before API calls. If, for some reason, you want to turn this feature off, then you can pass the boolean value false for that param. see the example below for "SimbaContract.submitMethod without validation of params"

Integrating with Polyglot

/// UNDER CONSTRUCTION /// Polyglot is currently under construction, but will substantially streamline the process of interacting with your deployed smart contracts once fully implemented.

Testing

This section pertains to testing, if you have cloned SimbaTS. To run tests for SimbaTS, you'll want to have your SIMBA environment variables set in .simbachain.env at the top level of the /tests/ directory. So something like:

SIMBA_API_BASE_URL="https://simba-dev-api.platform.simbachain.com/"
SIMBA_AUTH_BASE_URL="https://simba-dev-api.platform.simbachain.com/"
SIMBA_AUTH_CLIENT_ID="Insert your client ID"
SIMBA_AUTH_CLIENT_SECRET="Insert your client secret"

Additionally, you can also configure SIMBA_LOG_LEVEL, if you want tests to be run at a different log level. So if you want tests to be run at "debug" level, in .simbachain.env you would set:

SIMBA_LOG_LEVEL="info"

unit and integration tests for developers

SimbaTS does not currently support running individual tests. unit tests and integration tests can be run separately, though.

To run integration tests, from the top level of your project, run:

npm run integration_test

To run unit test, from the top level of your project, run:

npm run unit_test

To run all tests, from the top level of your project, run:

npm test
