Not possible to create an Interface definition in synthetic AST #15497
Description
TypeScript Version: 2.3.2
Code
// A *self-contained* demonstration of the problem follows...
// There doesn't seem to be an API to create an Interface in the AST programmatically
const _implementsClause = ts.createHeritageClause(ts.SyntaxKind.ImplementsKeyword, [
ts.createExpressionWithTypeArguments([], ts.createIdentifier('MyInterface'))
]);
const _exportModifier = ts.createToken(ts.SyntaxKind.ExportKeyword);
const _classExpression = ts.createClassExpression([_exportModifier], 'MyClass', [], [_implementsClause], []);
const _classStatement = ts.createStatement(_classExpression);
let src = ts.createSourceFile('output.ts', '', ts.ScriptTarget.ES5, false, ts.ScriptKind.TS);
src = ts.updateSourceFileNode(src, [_classStatement]);Expected behavior:
There should be an API for creating an Interface definition in a synthetic AST.
Actual behavior:
Doesn't seem like the API exists.

You need to add a
createInterfaceDeclarationto factory.ts, something a la createClassDeclaration.mhegazy commentedon May 1, 2017
PRs welcomed.

Mohamed Hegazy (@mhegazy) will do! One question though: are there tests around these APIs? I couldn't find any.

No.
Add {create|update}InterfaceDeclaration methods (closes microsoft#15497)

Blaine Bublitz (@phated) can you also fix #15489 in your PR?

I'll submit another one for that but I'm tackling some interface stuff right now.
