chore: Rename generate-ts/nr commands to codegen. (#3843)
Browse files Browse the repository at this point in the history
* Get rid of generate-* commands on cli, in favour of `codegen` command
with optional `--ts` or `--nr` flags.
* Update docs to explain how to do a contract compilation now.

We'll also cover how to generate a helper [TypeScript interface](#typescript-interfaces) and an [Aztec.nr interface](#noir-interfaces) for easily interacting with your contract from your typescript app and from other Aztec.nr contracts, respectively.

## Compile using the CLI
## Compile using aztec-nargo

To compile a contract using the Aztec CLI, first [install it](../cli/cli-commands#installation).
To compile a contract using the Aztec's build of nargo.

Then run the `compile` command with the path to your [contract project folder](./layout.md#directory-structure), which is the one that contains the `Nargo.toml` file:
Run the `aztec-nargo compile` command within your [contract project folder](./layout.md#directory-structure), which is the one that contains the `Nargo.toml` file:

```
aztec-cli compile ./path/to/my_aztec_contract_project
```bash
aztec-nargo compile
```

This will output a JSON [artifact](./artifacts.md) for each contract in the project to a `target` folder containing their artifact, which you can use for deploying or interacting with your contracts.
This will output a JSON [artifact](./artifacts.md) for each contract in the project to a `target` folder containing the Noir ABI artifacts.

`aztec-cli` uses `noir_wasm` by default for compiling contracts. This helps reduce the developer overhead of installation and maintaining the noir compiler, `nargo`. However, if you prefer, you can use `nargo` to compile contracts with `aztec-cli` as so:
Before you can use the ABI it currently needs to be validated as being Aztec compatible, and transformed to an Aztec compatible ABI using `aztec-cli codegen`, passing a Noir ABI file or folder, and output location, e.g:

```bash
aztec-cli compile my-contract --compiler nargo # switches compiler to nargo
aztec-cli codegen ./aztec-nargo/output/target/path -o src/artifacts
```

When you specify `nargo` as your compiler, you need to make sure that you are using the correct version. You can find the [latest version information here](../updating.md#updating-nargo).
It can be useful to perform this compilation, validation and transformation in one go, so you may wish to chain the commands and perhaps add them to a package.json script. The below assumes your contract is in a folder called `contract` at your project root:

### Typescript Interfaces

You can use the compiler to autogenerate type-safe typescript classes for each of your contracts. These classes define type-safe methods for deploying and interacting with your contract based on their artifact.
```bash
(cd contract && aztec-nargo compile && aztec-cli codegen target -o ../src/artifacts)
```

To generate them, include a `--typescript` option in the compile command with a path to the target folder for the typescript files:
### Typescript Interfaces

```
aztec-cli compile --typescript ./path/to/typescript/src ./path/to/my_aztec_contract_project
```
You can use the codegenerator to autogenerate type-safe typescript classes for each of your contracts. These classes define type-safe methods for deploying and interacting with your contract based on their artifact.

You can also generate these interfaces from prebuilt artifacts using the `generate-typescript` command:
To generate them, include a `--ts` option in the codegen command with a path to the target folder for the typescript files:

```
aztec-cli generate-typescript ./path/to/my_aztec_contract_project
```bash
aztec-cli codegen ./aztec-nargo/output/target/path -o src/artifacts --ts
```

To make this easier, the compiler can generate contract interface structs that expose a convenience method for each function listed in a given contract artifact. These structs are intended to be used from another contract project that calls into the current one. For each contract, two interface structs are generated: one to be used from private functions with a `PrivateContext`, and one to be used from open functions with a `PublicContext`.

To generate them, include a `--interface` option in the compile command with a path to the target folder for the generated Aztec.nr interface files:

```
aztec-cli compile --interface ./path/to/another_aztec_contract_project/src ./path/to/my_aztec_contract_project
```

You can also generate these interfaces from prebuilt artifacts using the `generate-noir-interface` command:
To generate them, include a `--nr` option in the `codegen` command with a path to the target folder for the generated Aztec.nr interface files:

```
aztec-cli generate-noir-interface ./path/to/my_aztec_contract_project
```bash
aztec-cli codegen ./aztec-nargo/output/target/path -o ./path/to/output/folder --nr
