Polyglot
With Viash, you can use your preferred scripting language, or even mix and match as you please. Supported languages include: Bash, Python, R, Scala, JS and C#.
Flexible & Modular
A Viash component can be exported as a standalone or Docker executable or as a modular Nextflow module.
Unit Testing
Viash components come with unit testing built in, making debugging easier. Test all components, even while using them in a data pipeline.
All-Inclusive Executable
Every executable built by Viash comes with an intuitive CLI automatically. This includes command-line arguments, type-checking, checking of required parameters and ensuring the existence of required input files.
Nextflow Integration
Viash generates Nextflow modules from your component to create portable and scalable data pipelines that run platform-independent.
Containerization
Reproducibility by design. A custom Docker container is automatically generated based on your dependencies described in your metadata.
