## Unstable
|
||
|
|
|
||
|
|
Not all of Deno's features are ready for production yet. Features which are not
|
||
|
|
ready because they are still in draft phase are locked behind the `--unstable`
|
||
|
|
command line flag. Passing this flag does a few things:
|
||
|
|
|
||
|
|
- It enables the use of unstable APIs during runtime.
|
||
|
|
- It adds the
|
||
|
|
[`lib.deno.unstable.d.ts`](https://github.com/denoland/deno/blob/master/cli/js/lib.deno.unstable.d.ts)
|
||
|
|
file to the list of TypeScript definitions that are used for typechecking.
|
||
|
|
This includes the output of `deno types`.
|
||
|
|
|
||
|
|
You should be aware that unstable APIs have probably **not undergone a security
|
||
|
|
review**, are likely to have **breaking API changes** in the future and are
|
||
|
|
**not ready for production**.
