Push one CI template change to five hundred repositories
Fan one workflow change out over hundreds of repositories with a dry run, a checkpoint and three known end states, against four ways to stop copying the file.
How-to › Section 16
Model, configure and generate#
Spec languages for configuration, environment overlays, application models that generate artifacts, project generators, and templates that produce deterministic code.

Generate code and projects 2 guides
Scaffolding and repeatable generation: jostraca (component tree of Project, Folder, File, Content, Fragment, Slot, Inject, Copy; define then build; in-memory generation for tests; byte-identical TypeScript and Go implementations; inks interpolation) against Yeoman, Plop, Hygen, Cookiecutter, Copier, Nx generators, Projen and Rails generators; plus pushing one template change to hundreds of repositories (repo-manager, the gh CLI, the Terraform GitHub provider, Renovate presets).
Scaffold a Python API client project with Cookiecutter
Turn a Python client layout into a Cookiecutter template with derived names, a hook that survives a second run, and a test that bakes it into a temporary directory.
Engineer templates and AST transforms 1 guide
Deterministic generated code without a Voxgig tool: EJS, Handlebars, Mustache, Jinja and Go templates; AST-based generation with ts-morph, jscodeshift and go/ast; codemods across generated files; formatting after generation; golden-file and snapshot tests of generated output; stable ordering and no timestamps.
Make a Handlebars template produce byte-identical output
Sort the model, keep helpers pure, normalise line endings and compile strict, so a Handlebars template renders the same bytes everywhere, checked with sha256sum.
Generate the client instead of writing it#
Retries, timeouts, pagination and auth are the same problems in every client. Voxgig generates them from your OpenAPI description, in 23 languages, from one model.
