For most long running applications, iWF is a All-In-One solution to replace Database, MessageQueue and ElasticSearch.

It will not make you a 10x developer...but you may feel like one!

It's a simple and powerful WorkflowAsCode general purpose workflow engine.

Back by Cadence/Temporal as an interpreter.

• See Slide deck for what problems it is solving
• See Design doc for how it works

• Run make bins to build the binary iwf-server
• Then run ./iwf-server start to run the service . This defaults to serve workflows APIs with Temporal interpreter implementation. It requires to have local Temporal setup. See Run with local Temporal.
• Alternatively, run ./iwf-server --config config/development_cadence.yaml start to run with local Cadence. See below instructions for setting up local Cadence.
• Run make integTests to run all integration tests. This by default requires to have both local Cadence and Temporal to be set up.

1. Install openapi-generator using Homebrew if you haven't. See more documentation
2. Check out the idl submodule by running the command: git submodule update --init --recursive
3. Run the command git submodule update --remote --merge to update IDL to the latest commit
4. Run make idl-code-gen to refresh the generated code

1. Run a local Temporalite following the instruction. If you see error error setting up schema, try use command temporalite start --namespace default -f my_test.db instead to start.
2. Go to http://localhost:8233/ for Temporal WebUI

NOTE: alternatively, go to Temporal-dockercompose to run with docker 3. For attribute_test.go integTests, you need to register search attributes:

tctl adm cl asa -n CustomKeywordField -t Keyword
tctl adm cl asa -n CustomIntField -t Int

1. Run a local Cadence server following the instructions
2. Register a new domain if not haven cadence --do default domain register
3. Go to Cadence http://localhost:8088/domains/default/workflows?range=last-30-days
