How to Work With TEAL

I am working on learning TEAL. However, one of the problems I am running into is how to interact with the blockchain through the command line. I have been using chatGPT to learn the structures and syntax for TEAL code, but I have not been able to find a mechanism for deployment. One suggestion from chatGPT was:

goal clerk compile program.teal

But, the problem is there is no clear way to install goal, nor a description of the requirements. For example, in one post, How to install goal, it appears to use to TEAL you may need to run a node, which creates a whole new host of installation problems. For this purpose, I do not want to run a node if possible.

Ultimately, I am looking for a command line tool to deploy TEAL programs. Thanks!

The simplest way to develop smart contracts on Algorand is now to use algokit, which provides higher -level tooling than TEAL as well as all the required utilities.

Here is the quick start: AlgoKit quick start - Algorand Developer Portal
The quick start includes explanations on how to deploy your first smart contract.

That being said, you can install goal without running a full node: Install a node - Algorand Developer Portal
It will install a node and you may need to run it just to initialize it, but then you can stop the node and use goal clerk compile.

Thank you, @fabrice.

I usually compile teal code on the algod server like this

scholtz/beaker-arc34-boxes/blob/953840de721d90007c5a6e6780f8856c6a9d5eac/src/txs/deployTxs.ts#L19


      
          const deployTxs = async (input: IInput): Promise<algosdk.Transaction[]> => {
            const { deployerAccount, params, client } = input;
            params.fee = 1000;
            params.flatFee = true;
            let appArgs: Uint8Array[] = [];
          
          
  const approvalProgramTeal = fs.readFileSync("./artifacts/approval.teal");
          
          
  //console.log("approvalProgramTeal", approvalProgramTeal);
            var approvalProgram = await client
              .compile(new Uint8Array(approvalProgramTeal))
              .do()
              .catch((e) => {
                expect(e).toBeFalsy();
                console.log("e", e);
              });
            let approvalProgramBytes = new Uint8Array(Buffer.from(approvalProgram.result, "base64"));
          
          
  const clearProgramTeal = fs.readFileSync("./artifacts/clear.teal");
          
          
  //console.log("approvalProgramTeal", approvalProgramTeal);
