+
+## The Problem
+
+Your application has boundaries. Network requests/responses, file system reads,
+etc. When you're working with these boundaries, you need to be able to handle
+errors that may occur, even in TypeScript.
+
+TypeScript will typically make these boundaries much more obvious because it
+doesn't like not knowing what the type of something is. For example:
+
+```ts
+const formData = new FormData(formElement)
+const name = await formData.get('name')
+// name is `File | string | null`
+```
+
+Often it's a good idea to use a proper parsing library for situations like this,
+but for simple cases that can often feel like overkill. But you don't want to
+just ignore TypeScript because:
+
+> TypeScript is that brutally honest friend you put up with because they save
+> you from making terrible mistakes. –
+> [@kentcdodds](https://twitter.com/kentcdodds/status/1715562350835855396)
+
+So you check it:
+
+```ts
+const formData = new FormData(formElement)
+const name = await formData.get('name')
+// name is `File | string | null`
+if (typeof name !== 'string') {
+	throw new Error('Name must be a string')
+}
+// now name is `string` (and TypeScript knows it too)
+```
+
+You're fine throwing a descriptive error here because it's just _very_ unlikely
+this will ever happen and even if it does you wouldn't really know what to do
+about it anyway.
+
+It's not a big deal, but there's a tiny bit of boilerplate that would be nice to
+avoid. Especially when you find yourself doing this all over the codebase. This
+is the problem `@epic-web/invariant` solves.
+
+## The Solution
+
+Here's the diff from what we had above:
+
+```diff
+const formData = new FormData(formElement)
+const name = await formData.get('name')
+// name is `File | string | null`
+- if (typeof name !== 'string') {
+- 	throw new Error('Name must be a string')
+- }
++ invariant(typeof name === 'string', 'Name must be a string')
+// now name is `string` (and TypeScript knows it too)
+```
+
+It's pretty simple. But honestly, it's nicer to read, it throws a special
+`InvariantError` object to distinguish it from other types of errors, and we
+have another useful utility for throwing `Response` objects instead of `Error`
+objects which is handy
+[in Remix](https://remix.run/docs/en/main/route/loader#throwing-responses-in-loaders).
+
+## Usage
+
+### `invariant`
+
+The `invariant` function is used to assert that a condition is true. If the
+condition is false, it throws an error with the provided message.
+
+**Basic Usage**
+
+```ts
+import { invariant } from '@epic-web/invariant'
+
+const creature = { name: 'Dragon', type: 'Fire' }
+invariant(creature.name === 'Dragon', 'Creature must be a Dragon')
+```
+
+**Throwing a Response on False Condition**
+
+```ts
+import { invariant } from '@epic-web/invariant'
+
+const creature = { name: 'Unicorn', type: 'Magic' }
+invariant(creature.type === 'Fire', 'Creature must be of type Fire')
+// Throws: InvariantError: Creature must be of type Fire
+```
+
+**Using Callback for Error Message**
+
+```ts
+import { invariantResponse } from '@epic-web/invariant'
+
+const creature = { name: 'Elf', type: 'Forest' }
+invariant(creature.type === 'Water', () => 'Creature must be of type Water')
+// Throws: InvariantError: Creature must be of type Water
+```
+
+### `invariantResponse`
+
+The `invariantResponse` function works similarly to `invariant`, but instead of
+throwing an `InvariantError`, it throws a Response object.
+
+**Basic Usage**
+
+```ts
+import { invariantResponse } from '@epic-web/invariant'
+
+const creature = { name: 'Phoenix', type: 'Fire' }
+invariantResponse(creature.type === 'Fire', 'Creature must be of type Fire')
+```
+
+**Throwing a Response on False Condition**
+
+```ts
+import { invariantResponse } from '@epic-web/invariant'
+
+const creature = { name: 'Griffin', type: 'Air' }
+invariantResponse(creature.type === 'Water', 'Creature must be of type Water')
+// Throws: Response { status: 400, body: 'Creature must be of type Water' }
+```
+
+The response status default if 400 (Bad Request), but you'll find how to change
+that below.
+
+**Using Callback for Response Message**
+
+```ts
+import { invariantResponse } from '@epic-web/invariant'
+
+const creature = { name: 'Mermaid', type: 'Water' }
+invariantResponse(
+	creature.type === 'Land',
+	() => `Expected a Land creature, but got a ${creature.type} creature`,
+)
+```
+
+**Throwing a Response with Additional Options**
+
+```ts
+import { invariantResponse } from '@epic-web/invariant'
+
+const creature = { name: 'Cerberus', type: 'Underworld' }
+invariantResponse(
+	creature.type === 'Sky',
+	JSON.stringify({ error: 'Creature must be of type Sky' }),
+	{ status: 500, headers: { 'Content-Type': 'text/json' } },
+)
+```
+
+## Differences from [invariant](https://www.npmjs.com/package/invariant)
+
+There are three main differences. With `@epic-web/invariant`:
+
+1. Error messages are the same in dev and prod
+2. It's typesafe
+3. We support the common case (for Remix anyway) of throwing Responses as well
+   with `invariantResponse`.

+
+## Motivation
+The [PHC String Format][specs:phc] is an attempt to specify a common hash string format that’s a restricted & well defined subset of the Modular Crypt Format. New hashes are strongly encouraged to adhere to the PHC specification, rather than the much looser [Modular Crypt Format][specs:mcf].
+
+## Install
+
+```bash
+npm install --save @phc/format
+```
+
+## Usage
+
+```js
+const phc = require('@phc/format');
+
+const phcobj = {
+  id: 'pbkdf2-sha256',
+  params: {i: 6400},
+  salt: Buffer.from('0ZrzXitFSGltTQnBWOsdAw', 'base64'),
+  hash: Buffer.from('Y11AchqV4b0sUisdZd0Xr97KWoymNE0LNNrnEgY4H9M', 'base64'),
+};
+
+const phcstr = "$pbkdf2-sha256$i=6400$0ZrzXitFSGltTQnBWOsdAw$Y11AchqV4b0sUisdZd0Xr97KWoymNE0LNNrnEgY4H9M";
+
+phc.serialize(phcobj);
+// => phcstr
+
+phc.deserialize(phcstr);
+// => phcobj
+```
+
+You can also pass an optional version parameter.
+
+```js
+const phc = require('@phc/format');
+
+const phcobj = {
+  id: 'argon2i',
+  version: 19,
+  params: {
+    m: 120,
+    t: 5000,
+    p: 2
+  },
+  salt: Buffer.from('iHSDPHzUhPzK7rCcJgOFfg', 'base64'),
+  hash: Buffer.from('J4moa2MM0/6uf3HbY2Tf5Fux8JIBTwIhmhxGRbsY14qhTltQt+Vw3b7tcJNEbk8ium8AQfZeD4tabCnNqfkD1g', 'base64'),
+};
+
+const phcstr = "$argon2i$v=19$m=120,t=5000,p=2$iHSDPHzUhPzK7rCcJgOFfg$J4moa2MM0/6uf3HbY2Tf5Fux8JIBTwIhmhxGRbsY14qhTltQt+Vw3b7tcJNEbk8ium8AQfZeD4tabCnNqfkD1g";
+
+phc.serialize(phcobj);
+// => phcstr
+
+phc.deserialize(phcstr);
+// => phcobj
+```

+/**
+ * The `node:console` module provides a simple debugging console that is similar to
+ * the JavaScript console mechanism provided by web browsers.
+ *
+ * The module exports two specific components:
+ *
+ * * A `Console` class with methods such as `console.log()`, `console.error()`, and `console.warn()` that can be used to write to any Node.js stream.
+ * * A global `console` instance configured to write to [`process.stdout`](https://nodejs.org/docs/latest-v25.x/api/process.html#processstdout) and
+ * [`process.stderr`](https://nodejs.org/docs/latest-v25.x/api/process.html#processstderr). The global `console` can be used without importing the `node:console` module.
+ *
+ * _**Warning**_: The global console object's methods are neither consistently
+ * synchronous like the browser APIs they resemble, nor are they consistently
+ * asynchronous like all other Node.js streams. See the [`note on process I/O`](https://nodejs.org/docs/latest-v25.x/api/process.html#a-note-on-process-io) for
+ * more information.
+ *
+ * Example using the global `console`:
+ *
+ * ```js
+ * console.log('hello world');
+ * // Prints: hello world, to stdout
+ * console.log('hello %s', 'world');
+ * // Prints: hello world, to stdout
+ * console.error(new Error('Whoops, something bad happened'));
+ * // Prints error message and stack trace to stderr:
+ * //   Error: Whoops, something bad happened
+ * //     at [eval]:5:15
+ * //     at Script.runInThisContext (node:vm:132:18)
+ * //     at Object.runInThisContext (node:vm:309:38)
+ * //     at node:internal/process/execution:77:19
+ * //     at [eval]-wrapper:6:22
+ * //     at evalScript (node:internal/process/execution:76:60)
+ * //     at node:internal/main/eval_string:23:3
+ *
+ * const name = 'Will Robinson';
+ * console.warn(`Danger ${name}! Danger!`);
+ * // Prints: Danger Will Robinson! Danger!, to stderr
+ * ```
+ *
+ * Example using the `Console` class:
+ *
+ * ```js
+ * const out = getStreamSomehow();
+ * const err = getStreamSomehow();
+ * const myConsole = new console.Console(out, err);
+ *
+ * myConsole.log('hello world');
+ * // Prints: hello world, to out
+ * myConsole.log('hello %s', 'world');
+ * // Prints: hello world, to out

+ * The `node:diagnostics_channel` module provides an API to create named channels
+ * to report arbitrary message data for diagnostics purposes.
+ *
+ * It can be accessed using:
+ *
+ * ```js
+ * import diagnostics_channel from 'node:diagnostics_channel';
+ * ```
+ *
+ * It is intended that a module writer wanting to report diagnostics messages
+ * will create one or many top-level channels to report messages through.
+ * Channels may also be acquired at runtime but it is not encouraged
+ * due to the additional overhead of doing so. Channels may be exported for
+ * convenience, but as long as the name is known it can be acquired anywhere.
+ *
+ * If you intend for your module to produce diagnostics data for others to
+ * consume it is recommended that you include documentation of what named
+ * channels are used along with the shape of the message data. Channel names
+ * should generally include the module name to avoid collisions with data from
+ * other modules.
+ * @since v15.1.0, v14.17.0

+ * The `node:dns` module enables name resolution. For example, use it to look up IP
+ * addresses of host names.
+ *
+ * Although named for the [Domain Name System (DNS)](https://en.wikipedia.org/wiki/Domain_Name_System), it does not always use the
+ * DNS protocol for lookups. {@link lookup} uses the operating system
+ * facilities to perform name resolution. It may not need to perform any network
+ * communication. To perform name resolution the way other applications on the same
+ * system do, use {@link lookup}.
+ *
+ * ```js
+ * import dns from 'node:dns';
+ *
+ * dns.lookup('example.org', (err, address, family) => {
+ *   console.log('address: %j family: IPv%s', address, family);
+ * });
+ * // address: "93.184.216.34" family: IPv4
+ * ```
+ *
+ * All other functions in the `node:dns` module connect to an actual DNS server to
+ * perform name resolution. They will always use the network to perform DNS
+ * queries. These functions do not use the same set of configuration files used by {@link lookup} (e.g. `/etc/hosts`). Use these functions to always perform
+ * DNS queries, bypassing other name-resolution facilities.
+ *
+ * ```js
+ * import dns from 'node:dns';
+ *
+ * dns.resolve4('archive.org', (err, addresses) => {
+ *   if (err) throw err;
+ *
+ *   console.log(`addresses: ${JSON.stringify(addresses)}`);
+ *
+ *   addresses.forEach((a) => {
+ *     dns.reverse(a, (err, hostnames) => {
+ *       if (err) {

+ *       }

This package is for users who _only_ need undici types (such as for `@types/node`). It is published alongside every release of `undici`, so you can always use the same version.
