# gbt
**gbt:** rust implementation of the getBlockTemplate algorithm
This project was bootstrapped by [napi](https://www.npmjs.com/package/@napi-rs/cli).
## Installing gbt
Installing gbt requires a [supported version of Node and Rust](https://github.com/napi-rs/napi-rs#platform-support).
The build process also requires [Rust](https://www.rust-lang.org/tools/install) to be installed.
You can install the project with npm. In the project directory, run:
```sh
$ npm install
```
This fully installs the project, including installing any dependencies and running the build.
## Building gbt
If you have already installed the project and only want to run the build, run:
```sh
$ npm run build
```
This command uses the [napi build](https://www.npmjs.com/package/@napi-rs/cli) utility to run the Rust build and copy the built library into `./gbt.[TARGET_TRIPLE].node`.
## Exploring gbt
After building gbt, you can explore its exports at the Node REPL:
```sh
$ npm install
$ node
> require('.').hello()
"hello node"
```
## Available Scripts
In the project directory, you can run:
### `npm install`
Installs the project, including running `npm run build-release`.
### `npm build`
Builds the Node addon (`gbt.[TARGET_TRIPLE].node`) from source.
Additional [`cargo build`](https://doc.rust-lang.org/cargo/commands/cargo-build.html) arguments may be passed to `npm build` and `npm build-*` commands. For example, to enable a [cargo feature](https://doc.rust-lang.org/cargo/reference/features.html):
```
npm run build -- --feature=beetle
```
#### `npm build-debug`
Alias for `npm build`.
#### `npm build-release`
Same as [`npm build`](#npm-build) but, builds the module with the [`release`](https://doc.rust-lang.org/cargo/reference/profiles.html#release) profile. Release builds will compile slower, but run faster.
### `npm test`
Runs the unit tests by calling `cargo test`. You can learn more about [adding tests to your Rust code](https://doc.rust-lang.org/book/ch11-01-writing-tests.html) from the [Rust book](https://doc.rust-lang.org/book/).
## Project Layout
The directory structure of this project is:
```
gbt/
├── Cargo.toml
├── README.md
├── gbt.[TARGET_TRIPLE].node
├── package.json
├── src/
| └── lib.rs
└── target/
```
### Cargo.toml
The Cargo [manifest file](https://doc.rust-lang.org/cargo/reference/manifest.html), which informs the `cargo` command.
### README.md
This file.
### gbt.\[TARGET_TRIPLE\].node
The Node addon—i.e., a binary Node module—generated by building the project. This is the main module for this package, as dictated by the `"main"` key in `package.json`.
Under the hood, a [Node addon](https://nodejs.org/api/addons.html) is a [dynamically-linked shared object](https://en.wikipedia.org/wiki/Library_(computing)#Shared_libraries). The `"build"` script produces this file by copying it from within the `target/` directory, which is where the Rust build produces the shared object.
### package.json
The npm [manifest file](https://docs.npmjs.com/cli/v7/configuring-npm/package-json), which informs the `npm` command.
### src/
The directory tree containing the Rust source code for the project.
### src/lib.rs
The Rust library's main module.
### target/
Binary artifacts generated by the Rust build.
