JS output does not contain all of the require statements

[midknight41]

Hi there,

I installed 1.3 yesterday and my application no longer compiles correctly. Here's an example:

TS Input
import a = require("../dir1/file1");
import MongoClient = require('mongodb');
import b = require('../dir1/file2');
import c = require("../dir2/file1");

JS Output
var c = require("../dir2/file1");

For some reason three of the four lines did not make it into the JS file. All worked fine before I installed the new TypeScript.

Any thoughts?

@midknight41 can you provide more information about the use sites of these import statements. please note that the compiler will elide imports that are not used in value postions.
From the spec section 11.2.5:

An external import declaration is represented in the generated JavaScript as a variable initialized by a call to the 'require' function provided by the module system host. A variable declaration and 'require' call is emitted for a particular imported module only if the imported module, or a local alias (section 10.3) that references the imported module, is referenced as a PrimaryExpression somewhere in the body of the importing module. If an imported module is referenced only as a ModuleName or TypeQueryExpression, nothing is emitted.

Hey mhegazy,

Thanks for your response. I played around a bit and figured out a bit more. It seems to act up when the typeof statement is used as a private variable in a class. See below...

//This omits the MongoClient line
import configDomain = require('../domain/config');
import MongoClient = require('mongodb');
import config = require("../utils/config");

var mongoConfig = config.getConfig().mongoDB;

var repo = new Repository(MongoClient, mongoConfig);

export class Repository {
private config: configDomain.IMongoConfig;
private mongoClient: typeof MongoClient;

constructor(mongoClient: typeof MongoClient, config: configDomain.IMongoConfig) {
this.mongoClient = mongoClient;
this.config = config;
}
}

//This works fine when the var repo line is below the class definition
import configDomain = require('../domain/config');
import MongoClient = require('mongodb');
import config = require("../utils/config");

var mongoConfig = config.getConfig().mongoDB;

export class Repository {
private config: configDomain.IMongoConfig;
private mongoClient: typeof MongoClient;

constructor(mongoClient: typeof MongoClient, config: configDomain.IMongoConfig) {
this.mongoClient = mongoClient;
this.config = config;
}
}

var repo = new Repository(MongoClient, mongoConfig);

//Also works fine if you remove the typeof statement
import configDomain = require('../domain/config');
import MongoClient = require('mongodb');
import config = require("../utils/config");

var mongoConfig = config.getConfig().mongoDB;

var repo = new Repository(MongoClient, mongoConfig);

export class Repository {
private config: configDomain.IMongoConfig;
private mongoClient: any;

constructor(mongoClient: typeof MongoClient, config: configDomain.IMongoConfig) {
this.mongoClient = mongoClient;
this.config = config;
}
}

Hope that helps.

@midknight41 I think your issue may be fixed with this pull request #1132

looks like a duplicate of #1130
