Migration from v2

The dtsgenerator v3 has made the following braking changes from v2.

• Support Plug-in feature. See the Plug-in section for more information.
• Change the command line options.
  • Remove the --namespace option. Use the @dtsgenerator/replace-namespace plug-in instead.
  • Add the --config option. Mainly for setting up the Plug-in.
  • And add more options.
• TypeScript AST is now used internally to generate type definitions.

  • @dtsgenerator/decorate-typename : This plug-in can decorate the output type name.
  • @dtsgenerator/single-quote : This plug-in replace the quote mark to single.
