Hammer
Build Tool for Browser and Node Applications
[](https://badge.fury.io/js/%40sinclair%2Fhammer)
## Install

```
## Usage
Create an `index.html` file
```html
```
Run Hammer
```shell
$ hammer build index.html
```
Done
## Overview
Hammer is a command line tool for browser and node application development. It provides a command line interface to trivially run both browser and node applications and offers appropriate `watch` and `reload` workflows for each environment. It is designed with rapid application development in mind and requires little to no configuration to use.
Hammer was written to consolidate several disparate tools related to monitoring node processes (nodemon), building from HTML (parcel), mono repository support (lerna, nx) and project automation (gulp, grunt). It takes `esbuild` as its only dependency and is as much concerned with build performance as it is with dramatically reducing the number of development dependencies required for modern web application development.

## Serve
Use the `serve` command to start a development server that reloads pages on save.
```html
Hello World
```
```bash
$ hammer serve index.html
```
## Run
Use the `run` command to start a node process that restarts on save.
```bash
$ hammer run index.ts
$ hammer run "index.ts arg1 arg2" # use quotes to pass arguments
$ hammer run index.mts # node esm modules supported via .mts
```
## Watch
Use the `watch` command to start a compiler watch process only.
```bash
$ hammer watch worker.ts
```
## Monitor
Use the `monitor` command to execute shell commands on file change.
```bash
$ hammer monitor index.ts "deno run --allow-all index.ts"
```
## Tasks
Hammer provides a built-in task runner for automating various workflow at the command line. Tasks are created with JavaScript functions specified in a file named `hammer.mjs`. Hammer will search for the `hammer.mjs` file in the current working directory and setup a callable command line interface to each exported function. Hammer provides a global `shell(...)` function that can be used to start command line processes within each task. Additional functionality can be imported via ESM `import`. The following shows running a Hammer website and server watch process in parallel.
```typescript
//
// file: hammer.mjs
//
export async function start() {
await Promise.all([
shell(`hammer serve apps/website/index.html --dist dist/website`),
shell(`hammer run apps/server/index.ts --dist dist/server`)
])
}
```
```bash
$ hammer task start
```
## Libs
In mono repository projects, you can import shared libraries by using TypeScript `tsconfig.json` path aliasing.
```shell
/apps
/server
index.ts ───────────┐
/website │
index.html │
index.ts ───────────┤ depends on
/libs │
/shared │
index.ts <──────────┘
tsconfig.json
```
To enable `website` and `server` to import the `shared` library. Configure `tsconfig.json` in the project root as follows.
```javascript
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@libs/shared": ["libs/shared/index.ts"],
}
}
}
```
Once configured the `server` and `website` applications can import with the following.
```typescript
import { Foo } from '@libs/shared'
```
