compile multi-files based ts module into same scope

first it generate a index ts file that contains all the reference file paths of this module

the it compile a js from the generated ts file

install

npm install -g ts-module-opt

compile a module directory

ts-module-opt -r typings/index.d.ts src

compile multiple module directories, generate a js file for each module

ts-module-opt -r typings/index.d.ts modulePath1 modulePath2

parameters

• --reference {path}: add a reference file path to the tsc compiler
  • or -r {path}
• --target es5: change the tsc targert to es5, default is es6
  • or -t es5
• --declaration: generate the typescript declaration file (.d.ts)
  • or -d
• --sourceMap: generate the source map

benifits

• a main ts file is generate for the directory to maintain all the reference paths
• all module files are compiled into same scope
• exported types are compiled into same scope in the declaration
• reference to ModuleName.TypeName is optimited to just TypeName when they are in same module

limitations

• require tsc to be in system path
• all typescript files in directory need to be in same module
• if a type need to be used in a different file, that type must be exported even these files are in same module
• resolving dependency might not be 100% correct, and it requires the ts source code to use 4 spaces padding
