# RuntimeContext

one of the extension's six runtime contexts: what it may do and what it never does

[figure: RuntimeContext is a value at none scope. The drawing shows its fields and the objects that they point at.]

| property | value |
|---|---|
| kind | value |
| scope | none |
| key | none |
| store | none |
| family | sources |



## Fields


| field | type | required | note |
|---|---|---|---|
| `name` | `one of the service worker \| the side panel \| the content script \| the page hook \| the offscreen document \| the options page` | yes |  |
| `may` | `[text]` | yes |  |
| `never` | `[text]` | yes |  |



## Routes that use it
No route takes or returns RuntimeContext directly. The record holds it, and the objects that point at it reach it.
