|
A collection of all token providers. The token providers should be used when the authorization
|
|
type is going to be token based. For example, the `bearer` authorization type set using
|
|
[httpBearerAuth trait][http-bearer-auth-trait] in Smithy.
|
|
|
|
## Static Token Provider
|
|
|
|
```ts
|
|
import { fromStatic } from "@aws-sdk/token-providers";
|
|
|
|
const token = { token: "TOKEN" };
|
|
const staticTokenProvider = fromStatic(token);
|
|
|
|
const staticToken = await staticTokenProvider(); // returns { token: "TOKEN" }
|
|
```
|
|
|
|
## SSO Token Provider
|
|
|
|
```ts
|
|
import { fromSso } from "@aws-sdk/token-providers";
|
|
|
|
// returns token from SSO token cache or ssoOidc.createToken() call.
|
|
const ssoToken = await fromSso();
|
|
```
|
|
|
|
## Env Token Provider with Signing Name
|
|
|
|
```ts
|
|
import { fromEnvSigningName } from "@aws-sdk/token-providers";
|
|
|
|
// returns token from environment, where token's key is based on signing name.
|
|
const envSigningNameToken = await fromEnvSigningName({ signingName: "signing name" });
|
|
```
|
|
|
|
## Token Provider Chain
|
|
|
|
```ts
|
|
import { nodeProvider } from "@aws-sdk/token-providers";
|
|
|
|
// returns token from default providers.
|
|
const token = await nodeProvider();
|
|
```

### Development
|
|
|
|
This package contains a minimal copy of the SSO OIDC client, instead of relying on the full client, which
|
|
would cause a circular dependency.
|
|
|
|
When regenerating the bundled version of the SSO OIDC client, run the esbuild.js script and then make the following changes:
|
|
|
|
- Remove any dependency of the generated client on the credential chain such that it would create
|
|
a circular dependency back to this package. Because we only need the `CreateTokenCommand`, the client, and this command's
|
|
associated `Exception`s, it is possible to remove auth dependencies.
|
|
- Ensure all required packages are declared in the `package.json` of token-providers.
