Enums

Enums can be retrieved from source files, namespaces, or function bodies:

const enums = sourceFile.getEnums();
const enum1 = sourceFile.getEnum("Enum1");
const enum2 = sourceFile.getEnum(e => e.getMembers().length === 5);

Add/Insert

Add or insert enums to a source file, namespace, or function like declarations by calling addEnum(), addEnums(), insertEnum(), or insertEnums().

const enumDeclaration = sourceFile.addEnum({
    name: "EnumName",
    members: [{
        name: "member"
    }]
});

Remove

Call .remove():

enumDeclaration.remove();

Get all members

Use getMembers():

const members = enumDeclaration.getMembers();

Get member

Use getMember():

const member1 = enumDeclaration.getMember("member1");
const member2 = enumDeclaration.getMember(m => m.getValue() === 1);

Add/Insert member

Members can be added by calling addMember(), addMembers(), insertMember(), or insertMembers():

const member = enumDeclaration.addMember({
    name: "newMember",
    value: 10
});

Const enum

Check if it's a const enum via isConstEnum():

enumDeclaration.isConstEnum(); // returns: boolean

Get the const keyword via getConstKeyword():

enumDeclaration.getConstKeyword(); // returns: Node | undefined

Set if it's a const enum via setIsConstEnum(value):

enumDeclaration.setIsConstEnum(true);
enumDeclaration.setIsConstEnum(false);

Enum Members

const member = enumDeclaration.getMember("member");

Value

The value can be retrieved whether it is implicitly or explicitly defined:

enumMember.getValue(); // returns: string | number

It can also be set to a number:

enumMember.setValue(5);

Or a string:

enumMember.setValue("string value");

Removing

Call remove() on it:

enumMember.remove();
