This article covers some most basics uses of the Snowflake SDK

Build a once-off scheduled job

With Snowflake SDK, you can create a job with two lines of code.

const job = new JobBuilder()
   .jobName("hello world")
   .jobInstructions(instructions) 
   .scheduleOnce(tomorrow()) 
   .build(); 

await snowflake.createJob(job);

Build a recurring scheduled job

Schedule a job that runs every minute for 10 times.

const job = new JobBuilder() 
   .jobName("hello world") 
   .jobInstructions(instructions)    
   .scheduleCron("* * * * *", 10) .build(); 

await snowflake.createJob(job);

Schedule a job that runs at 10:00 AM on the first day of every month.

const job = new JobBuilder() 
   .jobName("hello world") 
   .jobInstructions(instructions) 
   .scheduleCron("0 10 1 * *") 
   .build(); 

await snowflake.createJob(job);

Build a program condition triggered job

Schedule a job that is triggered based on an arbitrary condition defined within the user program.

const job = new JobBuilder() 
   .jobName("hello world") 
   .jobInstructions(instructions) 
   .scheduleConditional(1) 
   .build(); 

await snowflake.createJob(job);

Build a self-funded job

Self-funded job will take an account for paying fees on its own by using the initial fund. Fee account is no longer used for paying the job's fee.

const job = new JobBuilder() 
   .jobName("hello world") 
   .jobInstruction(instructions) 
   .scheduleConditional(1); 
   .selfFunded(true) 
   .initialFund(100000) // 1000000 lamports 
   .build() 

await snowflake.createJob(job)

Update a job

await snowflake.updateJob(job);

Delete a job

await snowflake.deleteJob(jobPubkey);

Fetch Job by public key

await snowflake.fetch(jobPubkey);

Fetch Job by owner

await snowflake.fetchByOwner(owner);
