From a function
const context = ExecutionContext.fromContext(skedContext, {
requestSource: "my-cool-project",
userAgent: "my-cool-function"
});
The requestSource and userAgent options are important for observability and debugging, as they set the value for the X-Skedulo-Source and User-Agent headers that are automatically included in all requests made within this context.
From other execution contexts
const context = ExecutionContext.fromCredentials({
apiServer: user.apiBasePath,
apiToken: user.accessToken,
}, {
requestSource: "my-cool-project",
userAgent: "my-cool-function"
});
Once initialized, the context object provides access to the various services detailed in subsequent sections.
Execution Limits serve two main purposes:
By default, the following limit are set:
A warning is logged if a limit is violated.
Using default limits
// Initialize the execution context
const context = ExecutionContext.fromContext(skedContext, {
requestSource: "my-cool-project",
userAgent: "my-cool-function"
});
// Call services with the context
const artifactClient = context.newArtifactClient(ArtifactType.WEBHOOK);
const webhooks = await artifactClient.list();
const functionPromises = webhooks.map((webhook: any) => artifactClient.get(webhook.name));
await Promise.all(functionPromises);
// Get execution metrics
console.log(context.getExecutionMetrics());
Overriding limits
const limits = {
totalCalls: 50,
maxConcurrentRequests: 10,
maxMethodExecutionTimeMs: 10000,
throwOnViolation: true // Throws an error if limits are exceeded
};
const context = ExecutionContext.fromContext(skedContext, {
requestSource: "my-cool-project",
userAgent: "my-cool-function",
limits
});
Retrieves the values of configuration variables defined within a function. To use this helper, the execution context must be initialized from skedContext.
const secretValue = context.configHelper.getString('SECRET_NAME');
In addition to getString(), other available methods include getNumber() and getJson().

The ArtifactClient provides a unified way to manage various artifact types.
// Creating an Artifact Client for a specific type
const client = context.newArtifactClient(ArtifactType.CUSTOM_OBJECT);
Listing All Artifacts Retrieve all artifactse.
await client.list();
Using Artifact Parameters for CRUD Operations
When performing CRUD operations, provide ArtifactParams with the necessary values based on the artifact type.
type ArtifactParams = {
name?: string; // Artifact name (required for most operations)
objectName?: string; // Optional identifier for object-based artifacts
viewTypeName?: string; // Optional view type name if applicable
scope?: string; // Optional scope if applicable
};
Notes
objectName in Horizon artifacts.name is the slug for Horizon templates and defId for mobile extensions.// Get an artifact
await client.get({ name: "Jobs" });
// Create an artifact
const upsertStatus: any = await client.upsert({},
{
metadata: {
type: 'CustomObject'
},
name: 'Tasks',
label: 'Tasks',
description: 'Daily tasks'
}
);
// Wait for 2 seconds then poll the status
await new Promise(resolve => setTimeout(resolve, 2000));
const result = await client.status(upsertStatus.id);
// Update an artifact
await client.upsert(
{
name: 'Tasks'
},
{
metadata: {
type: 'CustomObject'
},
name: 'Tasks',
label: 'Tasks',
description: 'Daily tasks - updated'
}
);
// Delete an artifact
await client.delete(
{
name: 'Tasks'
}
);
// Create a query builder for the Jobs object
const queryBuilder = context.newQueryBuilder({
objectName: 'Jobs',
operationName: 'fetchJobWithJobAllocations',
readOnly: true
});
queryBuilder.withFields(['UID', 'Name'])
.withFilter("JobStatus != 'Complete'")
.withLimit(1)
.withOffset(1)
.withOrderBy('Name ASC');
// Add a child query for Job Allocations
queryBuilder.withChildQuery('JobAllocations')
.withFields(['UID', 'Name'])
.withParentQuery('Job')
.withFields(['UID', 'Name']);
// Add a parent query for Primary Region
queryBuilder.withParentQuery('Region')
.withFields(['UID', 'Name']);
// Finally, execute the query
let queryResult = await queryBuilder.execute();
console.log(queryResult.records);
console.log(queryResult.totalCount); // 5
console.log(queryResult.queryLimit); // maximum allowed limit returned in the X-Skedulo-Dynamic-Query-Limit response header
console.log(queryResult.pageInfo.hasNextPage); // true
console.log(queryResult.endCursor); // Mg==
console.log(queryResult.endOffset); // 1
The X-Graphql-Operation header is added to all GraphQL requests and contains the value of operationName.
The GraphQLQueryBuilder provides several methods to configure your queries:
Limiting Results:
withLimit(limit: number) - Sets the maximum number of records using the limit parameter (recommended)withFirst(first: number) - Sets the maximum number of records using the first parameter (use when first is specifically needed)// Recommended: Use withLimit() for the 'limit' parameter
queryBuilder.withLimit(100); // → GraphQL query uses: limit: 100
// When specifically needed: Use withFirst() for the 'first' parameter
queryBuilder.withFirst(100); // → GraphQL query uses: first: 100
Filtering and Ordering:
withFields(fields: string[]) - Specify which fields to retrievewithFilter(condition: string) - Add filter conditions to limit resultswithOrderBy(orderBy: string) - Set the sort order (e.g., 'Name ASC', 'CreatedDate DESC')Pagination:
withOffset(offset: number) - Set the starting position for resultswithCursor(after: string) - Use cursor-based pagination// Create a query builder for the Jobs object
const queryBuilder = context.newQueryBuilder({
objectName: 'Jobs',
operationName: 'fetchJobs',
readOnly: true
});
// Fetch data from pages 1 through 5 (inclusive)
const queryResult = await queryBuilder.executeAll(1, 5);
// Fetch data from the first 20 pages
const queryResult = await queryBuilder.executeAll();
The queryBuilder.executeAll method supports querying up to a maximum of 20 pages.
To execute multiple queries in a single request, use graphqlService.queryBatch. This method takes an array of query builders, sends them to the GraphQL batch endpoint, and returns an array of query results. This is useful for fetching data from multiple objects efficiently.
// Create query builders for Jobs and Contacts
const jobQueryBuilder = context.newQueryBuilder({
objectName: 'Jobs',
operationName: 'fetchJobs',
readOnly: true
});
jobQueryBuilder.withFields(['UID', 'Name'])
.withLimit(10);
const contactQueryBuilder = context.newQueryBuilder({
objectName: 'Contacts',
operationName: 'fetchContacts',
readOnly: true
});
contactQueryBuilder.withFields(['UID', 'FirstName', 'LastName'])
.withLimit(5);
// Execute batch query
const queryResults = await context.graphqlService.queryBatch([jobQueryBuilder, contactQueryBuilder]);
// Process results
const jobResults = queryResults[0];
const contactResults = queryResults[1];
console.log('Jobs:', jobResults.records);
console.log('Job Total Count:', jobResults.totalCount);
console.log('Contacts:', contactResults.records);
console.log('Contact Total Count:', contactResults.totalCount);
const recordsToUpdate = queryResult.records.map((record) => {
return {
UID: record.UID,
Name: record.Name + " - Updated"
}
});
const updateResult = await context.graphqlService.update({
objectName: 'Resources',
operationName: 'updateResources',
records: recordsToUpdate,
bulkOperation: true, // optional
suppressChangeEvents: true // optional
});
const upsertResult = await context.graphqlService.upsert({
objectName: 'Resources',
operationName: 'updateResources',
records: recordsToUpsert,
bulkOperation: true, // optional
suppressChangeEvents: true, // optional
keyField: "ExternalId"
});
// Define mutation parameters for inserting Jobs and deleting Contacts
const insertJobParams = {
objectName: 'Jobs',
operationName: 'insertJobs',
operation: GraphqlOperations.INSERT,
records: [
{ UID: 'job1', Name: 'Developer Job', Status: 'Open' },
{ UID: 'job2', Name: 'Designer Job', Status: 'Open' }
],
bulkOperation: true
};
const deleteContactParams = {
objectName: 'Contacts',
operationName: 'deleteContacts',
operation: GraphqlOperations.DELETE,
records: [
{ UID: 'contact1' },
{ UID: 'contact2' }
]
};
// Execute batch mutation
const mutationResults = await context.graphqlService.mutateBatch([insertJobParams, deleteContactParams]);
// Process results
const insertResult = mutationResults[0];
const deleteResult = mutationResults[1];
console.log('Inserted Job UIDs:', context.graphqlService.extractUIDs(insertResult));
console.log('Deleted Contact UIDs:', context.graphqlService.extractUIDs(deleteResult));
The bulkOperation and readOnly options help optimize large-scale mutations and read-heavy queries. When enabled, they automatically add the X-Skedulo-Bulk-Operation (for mutations) and X-Skedulo-Read-Only (for queries) headers to improve performance.
To reduce the impact on change event processing, especially during high-volume mutations, the suppressChangeEvents option can be used. This disables change history tracking, helping to minimize delays.
The GraphQL Service supports pagination using either offset-based or cursor-based strategies, allowing you to fetch large datasets incrementally.
Pagination with offset
while(queryResult.pageInfo.hasNextPage) {
queryBuilder.withOffset(queryResult.endOffset + 1);
queryResult = await queryBuilder.execute();
}
Pagination with cursor
while(queryResult.pageInfo.hasNextPage) {
queryBuilder.withCursor(queryResult.endCursor);
queryResult = await queryBuilder.execute();
}
The Resource Service consists of two main components:
The Resource Builder retrieves resource data, including availability, activities, scheduled jobs, tags, and other relevant details. By default, it enables the following options: useTag, useJobAllocation, useResourceShift, useActivity, useAvailabilityPattern, and useHoliday, with a time range set to 14 days from the current time.
Usage
// Define query parameters for resource fetching
const params = new ResourceQueryParam();
params.regionIds = new Set(['<region_id>']);
// Override default values
params.useTag = false;
params.startTime = new Date();
params.endTime = new Date(new Date().getTime() + 7 * 24 * 60 * 60 * 1000);// next 7 days from now
// Build resources with the given parameters
const resources = await context.resourceBuilder.build(params);
console.log(resources);
The Resource Validator takes a list of resources and jobs, and determines which resources are qualified to perform the jobs based on:
Usage
// Fetch jobs using GraphQL
const jobQueryResult = await context
.newQueryBuilder({ objectName: "Jobs", operationName: "fetchJobs", readOnly: true })
.withLimit(2)
.withFields(TenantObjects.Jobs.Fields)
.execute();
// Convert raw job data into structured Job entities
const jobs: Job[] = jobQueryResult.records.map((job) => EntityFactory.createJob(job));
// Define validation options
const validationOptions = {
checkAvailability: true, // Check if the resource is available
checkConflict: true, // Check for conflicting events
checkTag: true // Check if the resource has the required skills
};
// Create a validator instance
const validator = new ResourceValidator(validationOptions);
// Run validation
const result: ValidationResult = validator.validate(resources, jobs);
// Output results
console.log(JSON.stringify(result, null, 2));
const resourcesQualifiedForAtleastOneJob = result.getQualifiedResources();
const jobsWithAtLeastXQualifiedResources = result.getJobsWithXQualifiedResources(2);
const unqualifiedJobsWithReasons = result.getUnqualifiedJobsWithReasons();
Validation Output The Resource Validator returns a structured JSON output indicating which resources are qualified, and the reasons why certain jobs are not assigned. The results can be formatted to present a clearer qualification status along with detailed reasons.
console.log(JSON.stringify(result.format(), null, 2));

Provides a high-level interface for geolocation-related operations, built on top of GeoAPIClient.
Get Distance Matrix Computes travel distance and duration between origins and destinations. Handles cases where no route is available.
const origins = [{ lat: 55.93, lng: -3.118 }, { lat: 50.087, lng: 14.421 }];
const destinations = [{ lat: 50.087, lng: 14.421 }, { lat: 0, lng: 0 }];
const distanceMatrix: Map<string, DistanceMatrixEntry> = await context.geoService.getDistanceMatrix(origins, destinations);
for(const origin of origins) {
for(const destination of destinations) {
const key = context.geoService.createKey(origin, destination);
const entry = distanceMatrix.get(key);
console.log(`Origin-Destination: ${key} - Status: ${entry?.status}`);
if(entry?.status === "OK") {
console.log(`Distance: ${entry?.distance?.distanceInMeters} meters`);
console.log(`Duration: ${entry?.duration?.durationInSeconds} seconds`);
}
}
}
Get Address Suggestions Fetches address autocomplete suggestions and retrieves detailed place information.
const input = "1600 Amphitheatre Pkwy";
const suggestions: PlaceResponse[]|null = await context.geoService.getAddressSuggestions({ input, country: 'US' }, 2);
if (suggestions) {
suggestions.forEach((place, index) => {
console.log(`Place ${index + 1}: ${place.formattedAddress}`);
console.log(`Latitude: ${place.geometry.lat}, Longitude: ${place.geometry.lng}`);
});
} else {
console.log("No place details found.");
}
The Lock Service provides a locking mechanism to prevent concurrent execution of critical processes, such as batch jobs. It ensures that only one instance of a process can proceed at a time by using configuration variables with expiration timestamps.
// Acquire a lock, auto release after 5 minutes
const lockAcquired = await context.lockService.acquireLock({
name: 'MY_LOCK',
ttl: 5 * 60 * 1000, // 5 minutes
});
// Release a lock
await context.lockService.releaseLock('MY_LOCK');
The Batch Service offers a flexible and scalable solution for large-scale data processing.
start method to return a configured GraphQLQueryBuilder object. This builder should set up the query fields, filters, and any required ordering.execute method to implement the logic to process each batch of records (e.g., updates, deletes, logging).finish method to perform any final cleanup, such as logging the results or sending notifications.Below is an example of bulk job update.
import {
GraphBatch,
GraphqlOperations,
GraphQLQueryBuilder,
} from "@skedulo/pulse-solution-services";
export class BulkJobUpdate extends GraphBatch {
public result: string[] = [];
// This method is called once at the beginning of the batch process.
protected async start(): Promise<GraphQLQueryBuilder> {
const queryBuilder = this.context
.newQueryBuilder({objectName: "Jobs", operationName: "fetchJobsWithRegion"})
.withFields(["UID", "Name", "Start"])
.withOrderBy("Name ASC");
queryBuilder.withParentQuery("Region").withFields(["UID", "Name"]);
return queryBuilder;
}
// This method is called for each batch of records.
protected async execute(records: any[]): Promise<void> {
const recordsToUpdate = records.map((record) => ({
UID: record.UID,
Description: `${record.Name} scheduled for ${new Date(record.Start).toLocaleDateString("en-GB")} in ${record.Region.Name}`,
}));
await this.context.graphqlService.mutate({
objectName: "Jobs",
operation: GraphqlOperations.UPDATE,
operationName: "updateJobs",
records: recordsToUpdate
});
this.result.push(...records.map((record) => record.Name));
}
// This method is called once at the end of the batch process.
protected async finish(): Promise<void> {
this.context.logger.info(`Processed ${this.result.length} records.`);
}
}
Run the batch
const context = ExecutionContext.fromCredentials({
apiServer: user.apiBasePath,
apiToken: user.user.accessToken,
});
const batch = new BulkJobUpdate(context, {
batchSize: 10,
maxBatches: 10,
strategy: PaginationStrategy.CURSOR,
delaySeconds: 1,
});
await batch.run();
The Unique Batch ensures that only one instance runs at a time. It leverages the Lock Service to prevent concurrent executions. The default lock duration is 16 minutes, configurable via the lockTtl setting.
Implementation
To create a unique batch, extend the UniqueGraphBatch class, everything else remains the same as a regular GraphBatch.
export class UniqueBulkJobUpdate extends UniqueGraphBatch {
Run a unique batch
const batch = new UniqueBulkJobUpdate(context, {
batchSize: 10,
maxBatches: 10,
strategy: PaginationStrategy.CURSOR,
delaySeconds: 1,
lockTtl: 5 * 60 * 1000, // 5 minutes - optional
});
batch.run(); // Runs successfully
batch.run(); // Fails (lock still active)
The Cache Service enables efficient data sharing between function executions and improves performance by reducing redundant operations and API calls.
// Multi-layer cache
const metadata: object[] = await context.inMemoryCache.get(
"METADATA",{
useSecondaryCache: true,
}
)
The log method decorator helps streamline debugging by tracking key function executions, including their inputs and outputs.
class ExampleService {
@LogMethod("example_space")
processData(input: string): string {
return `Processed: ${input}`;
}
}
Two environment variables control logging behavior:
