Managing Fleek Functions with the Fleek SDK
The Fleek SDK lets you create, deploy, and manage Fleek Functions within your applications. This document outlines the available methods for interacting with the Fleek Functions service.
The FunctionsClient class provides an interface for managing Fleek Functions, enabling users to create, deploy, update, list, and delete serverless functions via the Fleek SDK.
Methods
get
Retrieve a specific Fleek Function by its name.
Function Signature
get({ name }: GetFleekFunctionArgs): Promise<FleekFunction>
Parameters
name(string) - The name of the Fleek Function to retrieve.
Returns
A Promise resolving to an object containing:
- Function metadata, including
id,name,slug,invokeUrl,projectId,status, andcreatedAt. - Deployment details, including
currentDeploymentanddeployments.
Usage Example
const functionData = await functionsClient.get({ name: 'my-function' });
console.log(functionData.invokeUrl);
list
Retrieve a list of all Fleek Functions.
Function Signature
list(): Promise<FleekFunction[]>
Returns
A Promise resolving to an array of Fleek Functions with details such as id, name, slug, status, and deployments.
Usage Example
const functions = await functionsClient.list();
functions.forEach((fn) => console.log(fn.name));
listDeployments
Retrieve all deployments associated with a specific function.
Function Signature
listDeployments({ functionId }: ListFleekFunctionArgs): Promise<FleekFunctionDeployment[]>
Parameters
functionId(string) - The unique identifier of the Fleek Function.
Returns
A Promise resolving to an array of Fleek Function deployments with attributes such as id, cid, createdAt, updatedAt, and sgx.
Usage Example
const deployments = await functionsClient.listDeployments({
functionId: '12345',
});
deployments.forEach((deployment) => console.log(deployment.cid));
create
Create a new Fleek Function.
Function Signature
create({ name, siteId }: CreateFleekFunctionArgs): Promise<FleekFunction>
Parameters
name(string) - The name of the function to create.siteId(string) - The associated site ID.
Returns
A Promise resolving to a Fleek Function object with details such as id, name, slug, and invokeUrl.
Usage Example
const newFunction = await functionsClient.create({
name: 'my-new-function',
siteId: 'site123',
});
console.log(newFunction.id);
deploy
Deploy a new version of a Fleek Function.
Function Signature
deploy({ functionId, cid, sgx, blake3Hash, assetsCid }: DeployFleekFunctionArgs): Promise<FleekFunctionDeployment>
Parameters
functionId(string) - The function ID to deploy.cid(string) - The content identifier (CID) of the deployment.sgx(boolean) - Whether SGX (secure enclave execution) is enabled.blake3Hash(string) - The Blake3 hash of the deployment.assetsCid(string, optional) - CID of associated assets.
Returns
A Promise resolving to a Fleek Function deployment object with id, cid, createdAt, and updatedAt.
Usage Example
const deployment = await functionsClient.deploy({
functionId: '12345',
cid: 'Qm...',
sgx: false,
blake3Hash: 'abc123',
});
console.log(deployment.id);
delete
Delete a Fleek Function by ID.
Function Signature
delete({ id }: DeleteFleekFunctionArgs): Promise<FleekFunction>
Parameters
id(string) - The unique identifier of the Fleek Function.
Returns
A Promise resolving to the deleted Fleek Function’s details.
Usage Example
const deletedFunction = await functionsClient.delete({ id: '12345' });
console.log(`Deleted function: ${deletedFunction.name}`);
update
Update an existing Fleek Function.
Function Signature
update({ id, slug, name, status }: UpdateFleekFunctionArgs): Promise<FleekFunction>
Parameters
id(string) - The function ID.slug(string, optional) - The updated function slug.name(string, optional) - The new function name.status(FleekFunctionStatus, optional) - The updated function status.
Returns
A Promise resolving to the updated Fleek Function details.
Usage Example
const updatedFunction = await functionsClient.update({
id: '12345',
name: 'updated-function',
});
console.log(updatedFunction.name);
Notes
- Ensure that API authentication is properly configured.
- Function names must be unique within a project.
- Deleting a function removes its reference, but deployments may persist.
