## Install
```

npm i @tsndr/cloudflare-worker-jwt
```
## Examples
### Basic Example
```typescript
async () => {
import jwt from '@tsndr/cloudflare-worker-jwt'
import jwt from "@tsndr/cloudflare-worker-jwt"
// Creating a token
const token = await jwt.sign({ name: 'John Doe', email: 'john.doe@gmail.com' }, 'secret')
// Create a token
const token = await sign({
sub: "1234",
name: "John Doe",
email: "john.doe@gmail.com"
}, "secret")
// Verifing token
const isValid = await jwt.verify(token, 'secret')
// Verify token
const verifiedToken = await verify(token, "secret")
// Check for validity
if (!isValid)
// Abort if token isn't valid
if (!verifiedToken)
return
// Decoding token
const { payload } = jwt.decode(token)
// Access token payload
const { payload } = verifiedToken
// { sub: "1234", name: "John Doe", email: "john.doe@gmail.com" }
}
```

### Sign
#### `jwt.sign(payload, secret, [options])`
#### `sign(payload, secret, [options])`
Signs a payload and returns the token.
#### Arguments
Argument | Type | Status | Default | Description
------------------------ | ------------------ | -------- | ----------- | -----------
Argument | Type | Status | Default | Description
------------------------ | ----------------------------------- | -------- | ----------- | -----------
`payload` | `object` | required | - | The payload object. To use `nbf` (Not Before) and/or `exp` (Expiration Time) add `nbf` and/or `exp` to the payload.
`secret` | `string`, `JsonWebKey`, `CryptoKey` | required | - | A string which is used to sign the payload.
`options` | `string`, `object` | optional | `HS256` | Either the `algorithm` string or an object.
`options.algorithm` | `string` | optional | `HS256` | See [Available Algorithms](#available-algorithms)
`options.keyid` | `string` | optional | `undefined` | The `keyid` or `kid` to be set in the header of the resulting JWT.
#### `return`
Returns token as a `string`.
<hr>
### Verify
#### `jwt.verify(token, secret, [options])`
#### `verify(token, secret, [options])`
Verifies the integrity of the token and returns a boolean value.
Verifies the integrity of the token.
Argument | Type | Status | Default | Description
------------------------ | ------------------ | -------- | ------- | -----------
`token` | `string` | required | - | The token string generated by `jwt.sign()`.
Argument | Type | Status | Default | Description
------------------------ | ----------------------------------- | -------- | ------- | -----------
`token` | `string` | required | - | The token string generated by `sign()`.
`secret` | `string`, `JsonWebKey`, `CryptoKey` | required | - | The string which was used to sign the payload.
`options` | `string`, `object` | optional | `HS256` | Either the `algorithm` string or an object.
`options.algorithm` | `string` | optional | `HS256` | See [Available Algorithms](#available-algorithms)
`options.clockTolerance` | `number` | optional | `0` | Clock tolerance in seconds, to help with slighly out of sync systems.
`options.throwError` | `boolean` | optional | `false` | By default this we will only throw implementation errors, only set this to `true` if you want verification errors to be thrown as well.
`options.throwError` | `boolean` | optional | `false` | By default this we will only throw integration errors, only set this to `true` if you want verification errors to be thrown as well.
#### `throws`
If `options.throwError` is `true` and the token is invalid, an error will be thrown.
Throws integration errors and if `options.throwError` is set to `true` also throws `ALG_MISMATCH`, `NOT_YET_VALID`, `EXPIRED` or `INVALID_SIGNATURE`.
#### `return`
Returns `true` if signature, `nbf` (if set) and `exp` (if set) are valid, otherwise returns `false`.
<hr>
Returns the decoded token or `undefined`.
### Decode
#### `jwt.decode(token)`
Returns the payload **without** verifying the integrity of the token. Please use `jwt.verify()` first to keep your application secure!
Argument | Type | Status | Default | Description
----------- | -------- | -------- | ------- | -----------
`token` | `string` | required | - | The token string generated by `jwt.sign()`.
#### `return`
Returns an `object` containing `header` and `payload`:
```javascript
```typescript
{
header: {
alg: 'HS256',
typ: 'JWT'
alg: "HS256",
typ: "JWT"
},
payload: {
name: 'John Doe',
email: 'john.doe@gmail.com'
name: "John Doe",
email: "john.doe@gmail.com"
}
}
```
<hr>
### Decode
#### `decode(token)`
Just returns the decoded token **without** verifying verifying it. Please use `verify()` if you intend to verify it as well.
Argument | Type | Status | Default | Description
----------- | -------- | -------- | ------- | -----------
`token` | `string` | required | - | The token string generated by `sign()`.
#### `return`
Returns an `object` containing `header` and `payload`:
```typescript
{
header: {
alg: "HS256",
typ: "JWT"
},
payload: {
name: "John Doe",
email: "john.doe@gmail.com"
}
}
```
