[Arcjet][arcjet] helps developers protect their apps in just a few lines of
code. Implement rate limiting, bot protection, email verification, and defense
against common attacks.
This is the [Arcjet][arcjet] local analysis engine.
- [npm package (`@arcjet/analyze`)](https://www.npmjs.com/package/@arcjet/analyze)
- [GitHub source code (`analyze/` in `arcjet/arcjet-js`)](https://github.com/arcjet/arcjet-js/tree/main/analyze)
## Installation
```shell
npm install -S @arcjet/analyze
```
## Example
```ts
import { generateFingerprint, isValidEmail } from "@arcjet/analyze";
const fingerprint = generateFingerprint("127.0.0.1");
console.log("fingerprint: ", fingerprint);
const valid = isValidEmail("hello@example.com");
console.log("is email valid?", valid);
```
## Implementation
This package uses the Wasm bindings provided by `@arcjet/analyze-wasm` to
call various functions that are exported by our wasm bindings.
We chose to put this logic in a separate package because we need to change the
import structure for each runtime that we support in the wasm bindings. Moving
this to a separate package allows us not to have to duplicate code while providing
a combined higher-level api for calling our core functionality in Wasm.
