# Client

### E2B

E2B client with an explicitly bound connection configuration.

The resources exposed by the client (E2B.Sandbox,
E2B.Volume, E2B.Template, E2B.Secret) behave exactly
like the top-level `Sandbox` / `Volume` / `Template` / `Secret` exports,
except the options passed to the client are used as the defaults instead of
the environment variables.
Per-call options still take precedence over the client's options.

Multiple clients are fully isolated from each other and from the top-level
env-configured exports.

#### Example

```ts theme={"theme":{"light":"github-light","dark":"github-dark-default"}}
import { E2B } from 'e2b'

const client = new E2B({ apiKey: 'e2b_...', domain: 'e2b.dev' })

const sandbox = await client.Sandbox.create()
const volumes = await client.Volume.list()
await client.Template.build(client.Template().fromPythonImage('3'), 'my-env')
```

#### Constructors

```ts theme={"theme":{"light":"github-light","dark":"github-dark-default"}}
new E2B(opts?: E2BClientOpts): E2B
```

Create a new client with the connection options bound to it.

###### Parameters

| Parameter | Type | Description |
| - | - | - |
| `opts`? | `E2BClientOpts` | connection options used as the defaults for every call made through this client's resource classes. |

###### Returns

`E2B`

#### Properties

| Property | Modifier | Type | Description |
| - | - | - | - |
| <a id="sandbox" /> `Sandbox` | `readonly` | *typeof* `Sandbox` | `Sandbox` class bound to this client's connection configuration. |
| <a id="secret" /> `Secret` | `readonly` | *typeof* `Secret` | `Secret` class bound to this client's connection configuration. |
| <a id="template" /> `Template` | `readonly` | `CallableTemplate`\<*typeof* `TemplateBase`> | `Template` bound to this client's connection configuration. Both the builder (`client.Template()`) and the statics (`client.Template.build(...)`, `client.Template.exists(...)`, …) work like the top-level `Template`. |
| <a id="volume" /> `Volume` | `readonly` | *typeof* `Volume` | `Volume` class bound to this client's connection configuration. |

## Type Aliases

### E2BClientOpts

```ts theme={"theme":{"light":"github-light","dark":"github-dark-default"}}
type E2BClientOpts = Omit<ConnectionOpts, "signal">;
```

Connection options bound to an E2B client.

Same as ConnectionOpts without `signal`, which cancels a single
request and therefore can only be passed per call.
