# Source Map Support
[![NPM version](https://img.shields.io/npm/v/@cspotcode/source-map-support.svg?style=flat)](https://npmjs.org/package/@cspotcode/source-map-support)
[![NPM downloads](https://img.shields.io/npm/dm/@cspotcode/source-map-support.svg?style=flat)](https://npmjs.org/package/@cspotcode/source-map-support)
[![Build status](https://img.shields.io/github/workflow/status/cspotcode/node-source-map-support/Continuous%20Integration)](https://github.com/cspotcode/node-source-map-support/actions?query=workflow%3A%22Continuous+Integration%22)
This module provides source map support for stack traces in node via the [V8 stack trace API](https://github.com/v8/v8/wiki/Stack-Trace-API). It uses the [source-map](https://github.com/mozilla/source-map) module to replace the paths and line numbers of source-mapped files with their original paths and line numbers. The output mimics node's stack trace format with the goal of making every compile-to-JS language more of a first-class citizen. Source maps are completely general (not specific to any one language) so you can use source maps with multiple compile-to-JS languages in the same node process.
## Installation and Usage
#### Node support
```
$ npm install @cspotcode/source-map-support
```
Source maps can be generated using libraries such as [source-map-index-generator](https://github.com/twolfson/source-map-index-generator). Once you have a valid source map, place a source mapping comment somewhere in the file (usually done automatically or with an option by your transpiler):
```
//# sourceMappingURL=path/to/source.map
```
If multiple sourceMappingURL comments exist in one file, the last sourceMappingURL comment will be
respected (e.g. if a file mentions the comment in code, or went through multiple transpilers).
The path should either be absolute or relative to the compiled file.
From here you have two options.
##### CLI Usage
```bash
node -r @cspotcode/source-map-support/register compiled.js
# Or to enable hookRequire
node -r @cspotcode/source-map-support/register-hook-require compiled.js
```
##### Programmatic Usage
Put the following line at the top of the compiled file.
```js
require('@cspotcode/source-map-support').install();
```
It is also possible to install the source map support directly by
requiring the `register` module which can be handy with ES6:
```js
import '@cspotcode/source-map-support/register'
// Instead of:
import sourceMapSupport from '@cspotcode/source-map-support'
sourceMapSupport.install()
```
Note: if you're using babel-register, it includes source-map-support already.
It is also very useful with Mocha:
```
$ mocha --require @cspotcode/source-map-support/register tests/
```
#### Browser support
This library also works in Chrome. While the DevTools console already supports source maps, the V8 engine doesn't and `Error.prototype.stack` will be incorrect without this library. Everything will just work if you deploy your source files using [browserify](http://browserify.org/). Just make sure to pass the `--debug` flag to the browserify command so your source maps are included in the bundled code.
This library also works if you use another build process or just include the source files directly. In this case, include the file `browser-source-map-support.js` in your page and call `sourceMapSupport.install()`. It contains the whole library already bundled for the browser using browserify.
```html
<script src="browser-source-map-support.js"></script>
<script>sourceMapSupport.install();</script>
```
This library also works if you use AMD (Asynchronous Module Definition), which is used in tools like [RequireJS](http://requirejs.org/). Just list `browser-source-map-support` as a dependency:
```html
<script>
define(['browser-source-map-support'], function(sourceMapSupport) {
sourceMapSupport.install();
});
</script>
```
## Options
This module installs two things: a change to the `stack` property on `Error` objects and a handler for uncaught exceptions that mimics node's default exception handler (the handler can be seen in the demos below). You may want to disable the handler if you have your own uncaught exception handler. This can be done by passing an argument to the installer:
```js
require('@cspotcode/source-map-support').install({
handleUncaughtExceptions: false
});
```
This module loads source maps from the filesystem by default. You can provide alternate loading behavior through a callback as shown below. For example, [Meteor](https://github.com/meteor) keeps all source maps cached in memory to avoid disk access.
```js
require('@cspotcode/source-map-support').install({
retrieveSourceMap: function(source) {
if (source === 'compiled.js') {
return {
url: 'original.js',
map: fs.readFileSync('compiled.js.map', 'utf8')
};
}
return null;
}
});
```
The module will by default assume a browser environment if XMLHttpRequest and window are defined. If either of these do not exist it will instead assume a node environment.
In some rare cases, e.g. when running a browser emulation and where both variables are also set, you can explictly specify the environment to be either 'browser' or 'node'.
```js
require('@cspotcode/source-map-support').install({
environment: 'node'
});
```
To support files with inline source maps, the `hookRequire` options can be specified, which will monitor all source files for inline source maps.
```js
require('@cspotcode/source-map-support').install({
hookRequire: true
});
```
This monkey patches the `require` module loading chain, so is not enabled by default and is not recommended for any sort of production usage.
## Demos
#### Basic Demo
original.js:
```js
throw new Error('test'); // This is the original code
```
compiled.js:
```js
require('@cspotcode/source-map-support').install();
throw new Error('test'); // This is the compiled code
// The next line defines the sourceMapping.
//# sourceMappingURL=compiled.js.map
```
compiled.js.map:
```json
{
"version": 3,
"file": "compiled.js",
"sources": ["original.js"],
"names": [],
"mappings": ";;AAAA,MAAM,IAAI"
}
```
Run compiled.js using node (notice how the stack trace uses original.js instead of compiled.js):
```
$ node compiled.js
original.js:1
throw new Error('test'); // This is the original code
^
Error: test
at Object.<anonymous> (original.js:1:7)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3
```
#### TypeScript Demo
demo.ts:
```typescript
declare function require(name: string);
require('@cspotcode/source-map-support').install();
class Foo {
constructor() { this.bar(); }
bar() { throw new Error('this is a demo'); }
}
new Foo();
```
Compile and run the file using the TypeScript compiler from the terminal:
```
$ npm install source-map-support typescript
$ node_modules/typescript/bin/tsc -sourcemap demo.ts
$ node demo.js
demo.ts:5
bar() { throw new Error('this is a demo'); }
^
Error: this is a demo
at Foo.bar (demo.ts:5:17)
at new Foo (demo.ts:4:24)
at Object.<anonymous> (demo.ts:7:1)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3
```
There is also the option to use `-r source-map-support/register` with typescript, without the need add the `require('@cspotcode/source-map-support').install()` in the code base:
```
$ npm install source-map-support typescript
$ node_modules/typescript/bin/tsc -sourcemap demo.ts
$ node -r source-map-support/register demo.js
demo.ts:5
bar() { throw new Error('this is a demo'); }
^
Error: this is a demo
at Foo.bar (demo.ts:5:17)
at new Foo (demo.ts:4:24)
at Object.<anonymous> (demo.ts:7:1)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3
```
#### CoffeeScript Demo
demo.coffee:
```coffee
require('@cspotcode/source-map-support').install()
foo = ->
bar = -> throw new Error 'this is a demo'
bar()
foo()
```
Compile and run the file using the CoffeeScript compiler from the terminal:
```sh
$ npm install @cspotcode/source-map-support coffeescript
$ node_modules/.bin/coffee --map --compile demo.coffee
$ node demo.js
demo.coffee:3
bar = -> throw new Error 'this is a demo'
^
Error: this is a demo
at bar (demo.coffee:3:22)
at foo (demo.coffee:4:3)
at Object.<anonymous> (demo.coffee:5:1)
at Object.<anonymous> (demo.coffee:1:1)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
```
## Tests
This repo contains both automated tests for node and manual tests for the browser. The automated tests can be run using mocha (type `mocha` in the root directory). To run the manual tests:
* Build the tests using `build.js`
* Launch the HTTP server (`npm run serve-tests`) and visit
* http://127.0.0.1:1336/amd-test
* http://127.0.0.1:1336/browser-test
* http://127.0.0.1:1336/browserify-test - **Currently not working** due to a bug with browserify (see [pull request #66](https://github.com/evanw/node-source-map-support/pull/66) for details).
* For `header-test`, run `server.js` inside that directory and visit http://127.0.0.1:1337/

# Node.js Adapter for Hono
This adapter `@hono/node-server` allows you to run your Hono application on Node.js.
Initially, Hono wasn't designed for Node.js, but with this adapter, you can now use Hono on Node.js.
It utilizes web standard APIs implemented in Node.js version 18 or higher.
## Benchmarks
Hono is 3.5 times faster than Express.
Express:
```txt
$ bombardier -d 10s --fasthttp http://localhost:3000/
Statistics Avg Stdev Max
Reqs/sec 16438.94 1603.39 19155.47
Latency 7.60ms 7.51ms 559.89ms
HTTP codes:
1xx - 0, 2xx - 164494, 3xx - 0, 4xx - 0, 5xx - 0
others - 0
Throughput: 4.55MB/s
```
Hono + `@hono/node-server`:
```txt
$ bombardier -d 10s --fasthttp http://localhost:3000/
Statistics Avg Stdev Max
Reqs/sec 58296.56 5512.74 74403.56
Latency 2.14ms 1.46ms 190.92ms
HTTP codes:
1xx - 0, 2xx - 583059, 3xx - 0, 4xx - 0, 5xx - 0
others - 0
Throughput: 12.56MB/s
```
## Requirements
It works on Node.js versions greater than 18.x. The specific required Node.js versions are as follows:
- 18.x => 18.14.1+
- 19.x => 19.7.0+
- 20.x => 20.0.0+
Essentially, you can simply use the latest version of each major release.
## Installation
You can install it from the npm registry with `npm` command:
```sh
npm install @hono/node-server
```
Or use `yarn`:
```sh
yarn add @hono/node-server
```
## Usage
Just import `@hono/node-server` at the top and write the code as usual.
The same code that runs on Cloudflare Workers, Deno, and Bun will work.
```ts
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
const app = new Hono()
app.get('/', (c) => c.text('Hono meets Node.js'))
serve(app, (info) => {
console.log(`Listening on http://localhost:${info.port}`) // Listening on http://localhost:3000
})
```
For example, run it using `ts-node`. Then an HTTP server will be launched. The default port is `3000`.
```sh
ts-node ./index.ts
```
Open `http://localhost:3000` with your browser.
## Options
### `port`
```ts
serve({
fetch: app.fetch,
port: 8787, // Port number, default is 3000
})
```
### `createServer`
```ts
import { createServer } from 'node:https'
import fs from 'node:fs'
//...
serve({
fetch: app.fetch,
createServer: createServer,
serverOptions: {
key: fs.readFileSync('test/fixtures/keys/agent1-key.pem'),
cert: fs.readFileSync('test/fixtures/keys/agent1-cert.pem'),
},
})
```
### `overrideGlobalObjects`
The default value is `true`. The Node.js Adapter rewrites the global Request/Response and uses a lightweight Request/Response to improve performance. If you don't want to do that, set `false`.
```ts
serve({
fetch: app.fetch,
overrideGlobalObjects: false,
})
```
### `autoCleanupIncoming`
The default value is `true`. The Node.js Adapter automatically cleans up (explicitly call `destroy()` method) if application is not finished to consume the incoming request. If you don't want to do that, set `false`.
If the application accepts connections from arbitrary clients, this cleanup must be done otherwise incomplete requests from clients may cause the application to stop responding. If your application only accepts connections from trusted clients, such as in a reverse proxy environment and there is no process that returns a response without reading the body of the POST request all the way through, you can improve performance by setting it to `false`.
```ts
serve({
fetch: app.fetch,
autoCleanupIncoming: false,
})
```
## Middleware
Most built-in middleware also works with Node.js.
Read [the documentation](https://hono.dev/middleware/builtin/basic-auth) and use the Middleware of your liking.
```ts
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
import { prettyJSON } from 'hono/pretty-json'
const app = new Hono()
app.get('*', prettyJSON())
app.get('/', (c) => c.json({ 'Hono meets': 'Node.js' }))
serve(app)
```
## Serve Static Middleware
Use Serve Static Middleware that has been created for Node.js.
```ts
import { serveStatic } from '@hono/node-server/serve-static'
//...
app.use('/static/*', serveStatic({ root: './' }))
```
If using a relative path, `root` will be relative to the current working directory from which the app was started.
This can cause confusion when running your application locally.
Imagine your project structure is:
```
my-hono-project/
src/
index.ts
static/
index.html
```
Typically, you would run your app from the project's root directory (`my-hono-project`),
so you would need the following code to serve the `static` folder:
```ts
app.use('/static/*', serveStatic({ root: './static' }))
```
Notice that `root` here is not relative to `src/index.ts`, rather to `my-hono-project`.
### Options
#### `rewriteRequestPath`
If you want to serve files in `./.foojs` with the request path `/__foo/*`, you can write like the following.
```ts
app.use(
'/__foo/*',
serveStatic({
root: './.foojs/',
rewriteRequestPath: (path: string) => path.replace(/^\/__foo/, ''),
})
)
```
#### `onFound`
You can specify handling when the requested file is found with `onFound`.
```ts
app.use(
'/static/*',
serveStatic({
// ...
onFound: (_path, c) => {
c.header('Cache-Control', `public, immutable, max-age=31536000`)
},
})
)
```
#### `onNotFound`
The `onNotFound` is useful for debugging. You can write a handle for when a file is not found.
```ts
app.use(
'/static/*',
serveStatic({
root: './non-existent-dir',
onNotFound: (path, c) => {
console.log(`${path} is not found, request to ${c.req.path}`)
},
})
)
```
#### `precompressed`
The `precompressed` option checks if files with extensions like `.br` or `.gz` are available and serves them based on the `Accept-Encoding` header. It prioritizes Brotli, then Zstd, and Gzip. If none are available, it serves the original file.
```ts
app.use(
'/static/*',
serveStatic({
precompressed: true,
})
)
```
## ConnInfo Helper
You can use the [ConnInfo Helper](https://hono.dev/docs/helpers/conninfo) by importing `getConnInfo` from `@hono/node-server/conninfo`.
```ts
import { getConnInfo } from '@hono/node-server/conninfo'
app.get('/', (c) => {
const info = getConnInfo(c) // info is `ConnInfo`
return c.text(`Your remote address is ${info.remote.address}`)
})
```
## Accessing Node.js API
You can access the Node.js API from `c.env` in Node.js. For example, if you want to specify a type, you can write the following.
```ts
import { serve } from '@hono/node-server'
import type { HttpBindings } from '@hono/node-server'
import { Hono } from 'hono'
const app = new Hono<{ Bindings: HttpBindings }>()
app.get('/', (c) => {
return c.json({
remoteAddress: c.env.incoming.socket.remoteAddress,
})
})
serve(app)
```
The APIs that you can get from `c.env` are as follows.
```ts
type HttpBindings = {
incoming: IncomingMessage
outgoing: ServerResponse
}
type Http2Bindings = {
incoming: Http2ServerRequest
outgoing: Http2ServerResponse
}
```
## Direct response from Node.js API
You can directly respond to the client from the Node.js API.
In that case, the response from Hono should be ignored, so return `RESPONSE_ALREADY_SENT`.
> [!NOTE]
> This feature can be used when migrating existing Node.js applications to Hono, but we recommend using Hono's API for new applications.
```ts
import { serve } from '@hono/node-server'
import type { HttpBindings } from '@hono/node-server'
import { RESPONSE_ALREADY_SENT } from '@hono/node-server/utils/response'
import { Hono } from 'hono'
const app = new Hono<{ Bindings: HttpBindings }>()
app.get('/', (c) => {
const { outgoing } = c.env
outgoing.writeHead(200, { 'Content-Type': 'text/plain' })
outgoing.end('Hello World\n')
return RESPONSE_ALREADY_SENT
})
serve(app)
```
## Listen to a UNIX domain socket
You can configure the HTTP server to listen to a UNIX domain socket instead of a TCP port.
```ts
import { createAdaptorServer } from '@hono/node-server'
// ...
const socketPath = '/tmp/example.sock'
const server = createAdaptorServer(app)
server.listen(socketPath, () => {
console.log(`Listening on ${socketPath}`)
})
```

# @jridgewell/resolve-uri
> Resolve a URI relative to an optional base URI
Resolve any combination of absolute URIs, protocol-realtive URIs, absolute paths, or relative paths.
## Installation
```sh
npm install @jridgewell/resolve-uri
```
## Usage
```typescript
function resolve(input: string, base?: string): string;
```
```js
import resolve from '@jridgewell/resolve-uri';
resolve('foo', 'https://example.com'); // => 'https://example.com/foo'
```
| Input | Base | Resolution | Explanation |
|-----------------------|-------------------------|--------------------------------|--------------------------------------------------------------|
| `https://example.com` | _any_ | `https://example.com/` | Input is normalized only |
| `//example.com` | `https://base.com/` | `https://example.com/` | Input inherits the base's protocol |
| `//example.com` | _rest_ | `//example.com/` | Input is normalized only |
| `/example` | `https://base.com/` | `https://base.com/example` | Input inherits the base's origin |
| `/example` | `//base.com/` | `//base.com/example` | Input inherits the base's host and remains protocol relative |
| `/example` | _rest_ | `/example` | Input is normalized only |
| `example` | `https://base.com/dir/` | `https://base.com/dir/example` | Input is joined with the base |
| `example` | `https://base.com/file` | `https://base.com/example` | Input is joined with the base without its file |
| `example` | `//base.com/dir/` | `//base.com/dir/example` | Input is joined with the base's last directory |
| `example` | `//base.com/file` | `//base.com/example` | Input is joined with the base without its file |
| `example` | `/base/dir/` | `/base/dir/example` | Input is joined with the base's last directory |
| `example` | `/base/file` | `/base/example` | Input is joined with the base without its file |
| `example` | `base/dir/` | `base/dir/example` | Input is joined with the base's last directory |
| `example` | `base/file` | `base/example` | Input is joined with the base without its file |

# @jridgewell/sourcemap-codec
Encode/decode the `mappings` property of a [sourcemap](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit).
## Why?
Sourcemaps are difficult to generate and manipulate, because the `mappings` property the part that actually links the generated code back to the original source is encoded using an obscure method called [Variable-length quantity](https://en.wikipedia.org/wiki/Variable-length_quantity). On top of that, each segment in the mapping contains offsets rather than absolute indices, which means that you can't look at a segment in isolation you have to understand the whole sourcemap.
This package makes the process slightly easier.
## Installation
```bash
npm install @jridgewell/sourcemap-codec
```
## Usage
```js
import { encode, decode } from '@jridgewell/sourcemap-codec';
var decoded = decode( ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
assert.deepEqual( decoded, [
// the first line (of the generated code) has no mappings,
// as shown by the starting semi-colon (which separates lines)
[],
// the second line contains four (comma-separated) segments
[
// segments are encoded as you'd expect:
// [ generatedCodeColumn, sourceIndex, sourceCodeLine, sourceCodeColumn, nameIndex ]
// i.e. the first segment begins at column 2, and maps back to the second column
// of the second line (both zero-based) of the 0th source, and uses the 0th
// name in the `map.names` array
[ 2, 0, 2, 2, 0 ],
// the remaining segments are 4-length rather than 5-length,
// because they don't map a name
[ 4, 0, 2, 4 ],
[ 6, 0, 2, 5 ],
[ 7, 0, 2, 7 ]
],
// the final line contains two segments
[
[ 2, 1, 10, 19 ],
[ 12, 1, 11, 20 ]
]
]);
var encoded = encode( decoded );
assert.equal( encoded, ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
```
