Package Exports
- haystack-codegen
- haystack-codegen/dist/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (haystack-codegen) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Haystack Core Code Generation Tools
This project is classed as experimental!
Generates TypeScript code for haystack-core using haystack 4 defs.
- Generates TypeScript HDict interfaces
- Generates TypeScript type guard functions
APIs
Please click here for the API documentation.
Def docs
Please click here for the generated typedoc information for all defs.
Installation
npm install haystack-codegen
Or to install globally...
npm install haystack-codegen --global
Use
Use the -t
option to specify a space separated list of tags. For example, to create all the TypeScript code for a site
and ahu
tag...
defcodegen -t site ahu
If you want to generate TypeScript for all of the tags in a defs database run...
defcodegen -t *all*
Tip: try running typedoc
on the generated code for some nice looking HTML documentation!
Generating a file
The tool runs relative to the directory it is run in. The default generated file path is ./src/haystack/types.ts
. An alternative file can be specified via the -f
option...
defcodegen -t site ahu -f ./src/foo/bar.ts
Specifying the defs
The tool uses defs to generate TypeScript code. The defs database can be specified in a number of ways. By default...
- The tool looks for the
FIN_HOME
environment variable. If found, the defs will be compiled from the$FIN_HOME/lib/pod
directory. - The tool looks for the
FAN_HOME
environment variable. If found, the defs will be compiled from the$FAN_HOME/lib.fan
directory. In this scenario only POD files that start withph
will be used. - As a last resort, the tool will fallback to the def library embedded into
haystack-codegen
. Please note, this library could easily become out of date quickly.
Loading defs from a server
Due to the dynamic nature of defs, the most commonly used way is to load defs from a running server.
Ensure server authentication is disabled when doing this (for FIN/SkySpark use the -noAuth
option on start up).
For instance, to generate the TypeScript code for the site
tag from a server's demo project...
defcodegen -t site -u http://localhost:8080/api/demo
