Error Handling
All SDK methods return a response object or throw an error. If Error objects are specified in your OpenAPI Spec, the SDK will throw the appropriate Error type.
Error Object | Status Code | Content Type |
---|
errors.ErrorT | 404 | application/json |
errors.SDKError | 4xx-5xx | / |
Validation errors can also occur when either method arguments or data returned from the server do not match the expected format. The SDKValidationError
that is thrown as a result will capture the raw value that failed validation in an attribute called rawValue
. Additionally, a pretty()
method is available on this error that can be used to log a nicely formatted string since validation errors can list many issues and the plain error string may be difficult read when debugging.
import { Livepeer } from "livepeer";
import { SDKValidationError } from "livepeer/models/errors";
const livepeer = new Livepeer({
apiKey: "<YOUR_BEARER_TOKEN_HERE>",
});
async function run() {
let result;
try {
result = await livepeer.playback.get("<value>");
} catch (err) {
switch (true) {
case err instanceof SDKValidationError: {
console.error(err.pretty());
console.error(err.rawValue);
return;
}
case err instanceof errors.ErrorT: {
console.error(err);
return;
}
default: {
throw err;
}
}
}
console.log(result);
}
run();
Server Selection
Select Server by Index
You can override the default server globally by passing a server index to the serverIdx
optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:
# | Server | Variables |
---|
0 | https://livepeer.studio/api | None |
import { Livepeer } from "livepeer";
import {
Profile,
TranscodeProfileEncoder,
TranscodeProfileProfile,
Type,
} from "livepeer/models/components";
const livepeer = new Livepeer({
serverIdx: 0,
apiKey: "<YOUR_BEARER_TOKEN_HERE>",
});
async function run() {
const result = await livepeer.stream.create({
name: "test_stream",
pull: {
source: "https://myservice.com/live/stream.flv",
headers: {
Authorization: "Bearer 123",
},
location: {
lat: 39.739,
lon: -104.988,
},
},
playbackPolicy: {
type: Type.Webhook,
webhookId: "1bde4o2i6xycudoy",
webhookContext: {
streamerId: "my-custom-id",
},
refreshInterval: 600,
},
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
fps: 30,
fpsDen: 1,
quality: 23,
gop: "2",
profile: Profile.H264Baseline,
},
],
record: false,
recordingSpec: {
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
quality: 23,
fps: 30,
fpsDen: 1,
gop: "2",
profile: TranscodeProfileProfile.H264Baseline,
encoder: TranscodeProfileEncoder.H264,
},
],
},
multistream: {
targets: [
{
profile: "720p",
videoOnly: false,
id: "PUSH123",
spec: {
name: "My target",
url: "rtmps://live.my-service.tv/channel/secretKey",
},
},
],
},
});
console.log(result);
}
run();
Override Server URL Per-Client
The default server can also be overridden globally by passing a URL to the serverURL
optional parameter when initializing the SDK client instance. For example:
import { Livepeer } from "livepeer";
import {
Profile,
TranscodeProfileEncoder,
TranscodeProfileProfile,
Type,
} from "livepeer/models/components";
const livepeer = new Livepeer({
serverURL: "https://livepeer.studio/api",
apiKey: "<YOUR_BEARER_TOKEN_HERE>",
});
async function run() {
const result = await livepeer.stream.create({
name: "test_stream",
pull: {
source: "https://myservice.com/live/stream.flv",
headers: {
Authorization: "Bearer 123",
},
location: {
lat: 39.739,
lon: -104.988,
},
},
playbackPolicy: {
type: Type.Webhook,
webhookId: "1bde4o2i6xycudoy",
webhookContext: {
streamerId: "my-custom-id",
},
refreshInterval: 600,
},
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
fps: 30,
fpsDen: 1,
quality: 23,
gop: "2",
profile: Profile.H264Baseline,
},
],
record: false,
recordingSpec: {
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
quality: 23,
fps: 30,
fpsDen: 1,
gop: "2",
profile: TranscodeProfileProfile.H264Baseline,
encoder: TranscodeProfileEncoder.H264,
},
],
},
multistream: {
targets: [
{
profile: "720p",
videoOnly: false,
id: "PUSH123",
spec: {
name: "My target",
url: "rtmps://live.my-service.tv/channel/secretKey",
},
},
],
},
});
console.log(result);
}
run();
Custom HTTP Client
The TypeScript SDK makes API calls using an HTTPClient
that wraps the native
Fetch API. This
client is a thin wrapper around fetch
and provides the ability to attach hooks
around the request lifecycle that can be used to modify the request or handle
errors and response.
The HTTPClient
constructor takes an optional fetcher
argument that can be
used to integrate a third-party HTTP client or when writing tests to mock out
the HTTP client and feed in fixtures.
The following example shows how to use the "beforeRequest"
hook to to add a
custom header and a timeout to requests and how to use the "requestError"
hook
to log errors:
import { Livepeer } from "livepeer";
import { HTTPClient } from "livepeer/lib/http";
const httpClient = new HTTPClient({
fetcher: (request) => {
return fetch(request);
}
});
httpClient.addHook("beforeRequest", (request) => {
const nextRequest = new Request(request, {
signal: request.signal || AbortSignal.timeout(5000)
});
nextRequest.headers.set("x-custom-header", "custom value");
return nextRequest;
});
httpClient.addHook("requestError", (error, request) => {
console.group("Request Error");
console.log("Reason:", `${error}`);
console.log("Endpoint:", `${request.method} ${request.url}`);
console.groupEnd();
});
const sdk = new Livepeer({ httpClient });
Authentication
Per-Client Security Schemes
This SDK supports the following security scheme globally:
Name | Type | Scheme |
---|
apiKey | http | HTTP Bearer |
To authenticate with the API the apiKey
parameter must be set when initializing the SDK client instance. For example:
import { Livepeer } from "livepeer";
import {
Profile,
TranscodeProfileEncoder,
TranscodeProfileProfile,
Type,
} from "livepeer/models/components";
const livepeer = new Livepeer({
apiKey: "<YOUR_BEARER_TOKEN_HERE>",
});
async function run() {
const result = await livepeer.stream.create({
name: "test_stream",
pull: {
source: "https://myservice.com/live/stream.flv",
headers: {
Authorization: "Bearer 123",
},
location: {
lat: 39.739,
lon: -104.988,
},
},
playbackPolicy: {
type: Type.Webhook,
webhookId: "1bde4o2i6xycudoy",
webhookContext: {
streamerId: "my-custom-id",
},
refreshInterval: 600,
},
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
fps: 30,
fpsDen: 1,
quality: 23,
gop: "2",
profile: Profile.H264Baseline,
},
],
record: false,
recordingSpec: {
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
quality: 23,
fps: 30,
fpsDen: 1,
gop: "2",
profile: TranscodeProfileProfile.H264Baseline,
encoder: TranscodeProfileEncoder.H264,
},
],
},
multistream: {
targets: [
{
profile: "720p",
videoOnly: false,
id: "PUSH123",
spec: {
name: "My target",
url: "rtmps://live.my-service.tv/channel/secretKey",
},
},
],
},
});
console.log(result);

Retries
Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.
To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:
import { Livepeer } from "livepeer";
import {
Profile,
TranscodeProfileEncoder,
TranscodeProfileProfile,
Type,
} from "livepeer/models/components";
const livepeer = new Livepeer({
apiKey: "<YOUR_BEARER_TOKEN_HERE>",
});
async function run() {
const result = await livepeer.stream.create(
{
name: "test_stream",
pull: {
source: "https://myservice.com/live/stream.flv",
headers: {
Authorization: "Bearer 123",
},
location: {
lat: 39.739,
lon: -104.988,
},
},
playbackPolicy: {
type: Type.Webhook,
webhookId: "1bde4o2i6xycudoy",
webhookContext: {
streamerId: "my-custom-id",
},
refreshInterval: 600,
},
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
fps: 30,
fpsDen: 1,

gop: "2",
profile: Profile.H264Baseline,
},
],
record: false,
recordingSpec: {
profiles: [
{
width: 1280,
name: "720p",
height: 720,
bitrate: 3000000,
quality: 23,
fps: 30,
fpsDen: 1,
gop: "2",
profile: TranscodeProfileProfile.H264Baseline,
encoder: TranscodeProfileEncoder.H264,
},
],
},
multistream: {
targets: [
{
profile: "720p",
videoOnly: false,
id: "PUSH123",
spec: {
name: "My target",
url: "rtmps://live.my-service.tv/channel/secretKey",
},
},
],
},
},
{
retries: {
strategy: "backoff",
backoff: {
initialInterval: 1,
maxInterval: 50,
exponent: 1.1,
maxElapsedTime: 100,
},
retryConnectionErrors: false,
},
}
);
console.log(result);
}
run();
If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:
import { Livepeer } from "livepeer";
import {
Profile,
TranscodeProfileEncoder,
TranscodeProfileProfile,
Type,
} from "livepeer/models/components";
const livepeer = new Livepeer({
retryConfig: {
strategy: "backoff",
backoff: {
initialInterval: 1,
maxInterval: 50,
exponent: 1.1,
maxElapsedTime: 100,
},
retryConnectionErrors: false,
},
apiKey: "<YOUR_BEARER_TOKEN_HERE>",
});
async function run() {
const result = await livepeer.stream.create({
name: "test_stream",
pull: {
source: "https://myservice.com/live/stream.flv",
headers: {
Authorization: "Bearer 123",
},

},
],
},
multistream: {
targets: [
{
profile: "720p",
videoOnly: false,
id: "PUSH123",
spec: {
name: "My target",
url: "rtmps://live.my-service.tv/channel/secretKey",
},
},
],
},
});
console.log(result);
}
run();
Debugging
To log HTTP requests and responses, you can pass a logger that matches console
's interface as an SDK option.
[!WARNING]
Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.
import { Livepeer } from "livepeer";
const sdk = new Livepeer({ debugLogger: console });
