示例1: it
it('should quote identifiers quoted in the source', () => {
const sourceText = `
import {Component} from '@angular/core';
@Component({
providers: [{ provide: 'SomeToken', useValue: {a: 1, 'b': 2, c: 3, 'd': 4}}]
})
export class MyComponent {}
`;
const source = ts.createSourceFile('test.ts', sourceText, ts.ScriptTarget.Latest);
const collector = new MetadataCollector({quotedNames: true});
const stubHost = new StubReflectorHost();
const symbolCache = new StaticSymbolCache();
const symbolResolver =
new StaticSymbolResolver(stubHost, symbolCache, new MockSummaryResolver());
const reflector = new StaticReflector(symbolResolver);
// Get the metadata from the above source
const metadata = collector.getMetadata(source);
const componentMetadata = metadata.metadata['MyComponent'];
// Get the first argument of the decorator call which is passed to @Component
expect(isClassMetadata(componentMetadata)).toBeTruthy();
if (!isClassMetadata(componentMetadata)) return;
const decorators = componentMetadata.decorators;
const firstDecorator = decorators[0];
expect(isMetadataSymbolicCallExpression(firstDecorator)).toBeTruthy();
if (!isMetadataSymbolicCallExpression(firstDecorator)) return;
const firstArgument = firstDecorator.arguments[0];
// Simplify this value using the StaticReflector
const context = reflector.getStaticSymbol('none', 'none');
const argumentValue = reflector.simplify(context, firstArgument);
// Convert the value to an output AST
const outputAst = convertValueToOutputAst(argumentValue);
const statement = outputAst.toStmt();
// Convert the value to text using the typescript emitter
const emitter = new TypeScriptEmitter(new StubImportResolver());
const text = emitter.emitStatements('module', [statement], []);
// Expect the keys for 'b' and 'd' to be quoted but 'a' and 'c' not to be.
expect(text).toContain('\'b\': 2');
expect(text).toContain('\'d\': 4');
expect(text).not.toContain('\'a\'');
expect(text).not.toContain('\'c\'');
});示例2: simplify
function simplify(context: StaticSymbol, value: any) {
return reflector.simplify(context, value);
