It is possible to add extra local data storage services in the Local Simple Runtime. A containerized test environment is great for testing and can be deleted at any time. These services can also be accessed directly via 127.0.0.1 instead of host.docker.internal.
Triggers - API route, MQ and scheduler - CLI commands.
Data Context is an object injected into logic functions during a task, which containes some key components:
CLI allows you to create data process projects locally and deploy them with console commands.
Connecting external databases with built-in drivers. Currently the following databases are supported:
API routes is one of the trigger features that can be deployed and managed from CLI, which make data processes RESTful-like. See Triggers commands for more details.
Message queue clients, publishers and subscribers together are one of the trigger features that can be deployed and managed from CLI.
Scheduler - schedules and scheduled jobs - together are one of the trigger features that can be deployed and managed from CLI. See Triggers commands for more details.
LOC data events allows users to generate a data flow or data trail to indicate who have sent and received data. These information can be very useful for two reasons:
Emit and query LOC data events.
This is the follow-up of Emit and Inspect Events, in which we've learned the basics of emitting events.
Accessing and writing remote files. Supports the following protocols/storage:
General, profile and login CLI commands.
For sending HTTP requests.
LOC v0.6 Release Note (legacy version)
For sharing data between tasks of one data process.
Log (debugging) messages to LOC.
Logic are the core elements of a data process. They contains the implementation of part of a data pipeline. And the session storage is the thing to link them up together.
Sending emails with a SMTP server.
Payload is the data sent by triggers as input and is accessible from the context object. Currently there are two payload types:
Project, data process and logic CLI commands.
This quick start will go through a tutorial of building a simple "Hello World" data process in LOC Studio using JavaScript.
LOC v0.6 has brought some new features and improvements since v0.5.0. This is also the first available version of LOC Documentation.
Finalise a JSON object as the result data. If the trigger is synchronized API route or message queue, it will be returned to the trigger.
For sharing data between logic during a task (execution) of a data process.
LOC CLI is the command line tool for developers to deploy data processes and manage other assets in LOC.
If a data process is deployed, it can be run without using triggers. This is exactly the same as the Execution function in Studio.
An overview of Studio functionalities.
Tag and unit CLI commands.
Some tips about handling errors in logic.
Local Simple Runtime is a Docker-based local LOC environment. It offers the following benefits:
