TypeScript SDK
Nodes & single runs
Discover node specs and run single nodes from the SDK.
Search the palette
import { BlitClient } from "@blitflow/sdk";
const client = new BlitClient({ apiKey: process.env.BLITFLOW_TOKEN });
const specs = await client.searchNodes({
query: "sprite",
category: "image",
limit: 10,
});All options are optional — omit them to list the whole palette.
Fetch one spec
const spec = await client.getNode("rd-fast");
// The spec's ports tell you exactly what to send:
for (const [name, port] of Object.entries(spec.inputs)) {
console.log(
name,
port.connector.id,
port.connector.optionValues ?? "",
port.connector.defaultValue ?? "",
);
}Read optionValues before sending enum-like inputs (style, modes, sizes) —
values outside the enum fail validation. See Nodes &
specs.
Run a single node
For one-off inference, skip the workflow entirely:
const { outputs } = await client.runNode("rd-fast", {
prompt: "a brass key on black velvet",
removeBg: true,
seed: 7,
// data ports take Artifacts:
// init: { ref: "https://…/base.png" },
});
console.log(outputs.image); // { kind: "image", ref: "https://…", … }Scalars (string / number / boolean / null) work for value ports;
Artifacts for images and other binary data. The
call returns the node's outputs directly — no event stream.
