Generic TypeScript Merger
let tsm = require('@devonfw/ts-merger');
let mergedCode: string = tsm.merge(baseContents, pathContents, patchOverrides);Being:
- baseContents: contents of the base in a string
- patchContents: contents of the patch in a string
- patchOverrides(true/false): Being false, base will have priority in case of conflicts. With true, patch will have priority.
let tsm = require('@devonfw/ts-merger');
let mergedCode: string = tsm.merge(baseContents, pathContents, patchOverrides);The merger allows merging of this node kinds:
- ImportDeclaration
- ExportDeclaration
- ClassDeclaration
- InterfaceDeclaration
- Decorator
- FunctionDeclaration
- MethodDeclaration
- Parameter
- BodyMethod
- PropertyAssignment
- PropertyDeclaration
- Constructor
- ArrayLiteralExpression
- ObjectLiteralExpression
- CallExpression
- VariableAssignment
This version allows merging of TypeScript files that follow this structure:
- Array of imports
- Array of functions
- Array of variables
- Array of classes
##Examples
Base file
import a from 'b';
import f from 'g';
class Example1 {
private propertyFromBase: string;
oneMethod() {
let variable = 'base';
}
}Patch file
import c from 'd';
import h from 'g';
class Example1 {
private propertyFromPatch: number;
oneMethod() {
let variable = 'patch';
}
anotherMethod(){}
}
class AnotherClass {}Resultant merged code (patchOverrides=false)
import a from 'b';
import c from 'd';
import { f, h } from 'g';
class Example1 {
private propertyFromBase: string;
private propertyFromPatch: number;
oneMethod() {
let variable = 'base';
}
anotherMethod(){}
}
class AnotherClass {}Resulting merged code (patchOverrides=true)
import a from 'b';
import c from 'd';
import { f, h } from 'g';
class Example1 {
private propertyFromBase: string;
private propertyFromPatch: number;
oneMethod() {
let variable = 'patch';
}
anotherMethod(){}
}
class AnotherClass {}Next releases will include merge support for:
