TypeScript Merger

TS-Merger is a tool designed to parse and merge a base and a patch file into one single file depending on the merge strategy defined.

Currently, the merger supports the following AST node types:

1. ImportDeclaration

2. ClassDeclaration

3. Constructor

4. MethodDeclaration

5. Parameter

6. PropertyDeclaration

7. Decorator

8. ObjectLiteralExpression

9. ArrayLiteralExpression

10. PropertyAssignment

11. CallExpression

12. VariableAssignment

13. Body (only merges variable declarations with same identifier)

14. FunctionDeclaration

Requirements

1. Node 6.9.2 or higher

2. Webpack

   npm install -g webpack

Optional requirements

1. ts-node

   npm install -g ts-node

2. yarn

   npm install -g yarn

Usage

The TS Merger can be launched in two ways depending the file you want to launch:

1. Launching the TS code directly

   ts-node src\index.ts -f -b <<BASE_FILE_PATH>> -p <<PATCH_FILE_PATH>> -o <<OUTPUT_FILE_PATH>> -e <<ENCODING>>

ts-node src\index.ts -b <<BASE_FILE_PATH>> -p <<PATCH_FILE_PATH>> -e <<ENCODING>>

ts-node src\index.ts -f -b <<BASE_FILE_PATH>> -p <<PATCH_FILE_PATH>>

1. From compiled JS file resultant from webpack:

   node dist\tsmerger.js -f -b <<BASE_FILE_PATH>> -p <<PATCH_FILE_PATH>> -o <<OUTPUT_FILE_PATH>> -e <<ENCODING>>

node dist\tsmerger.js -b <<BASE_FILE_PATH>> -p <<PATCH_FILE_PATH>> -e <<ENCODING>>

node dist\tsmerger.js -f -b <<BASE_FILE_PATH>> -p <<PATCH_FILE_PATH>>

1. To set patchOverride to true just use the -f flag

2. If not -o or -e flags are used, no output file will be generated and UTF-8 encoding will be used.
