@blockless/sdk-ts

This sdk is designed to work with Javascript/Typescript and compile for the BLESS Javy WASM Engine. As such this engine does not have full support for Node / Web APIs, but a majority of pure JavaScript will work, including some of those from the npm ecosystem.

You don't need to use this SDK directly, it works as a module add on to your current npm project, or you can use blessnet CLI to initialize a project that uses this SDK.

npx blessnet init

The SDK natively supports

• json
• http
• crypto

Install this SDK

$ yarn add @blockless/sdk-ts
# or using npm
$ npm i @blockless/sdk-ts

Example of using this SDK.

import { InputProps, entryMain } from '@blockless/sdk-ts'
import { AbiCoder } from 'ethers'

interface Arguments {
	n: number
	v: string
}

entryMain(async (input: InputProps<Arguments>) => {
	console.log('\n Example: Stdin')

	if (Object.keys(input.args).length === 0) {
		console.log('Missing args.')
		return {}
	}

	const coder = AbiCoder.defaultAbiCoder()
	const coded = coder.encode(['string'], [input.args.v])

	return { nonce: input.args.n, value: coded }
})

How to build

bls-sdk-ts build ./index.ts -o <outDirectory> -f <outFile>

Building examples locally

Building the LLM example

npm run build && node ./dist/bundler build ./examples/llm/index.ts -o ./build -f llm-example.wasm --features llm

Re-install/update Javy and plugins

npm run build && node ./dist/bundler build ./examples/fetch/index.ts -o ./build -f fetch-example.wasm --update

Note: --update will force the re-installation of Javy and the plugins - getting the latest versions.

Uninstall Javy and plugins

npm run build && node ./dist/bundler uninstall
