Compile error but js get generated - visual-studio-2013

This is a new computer setup. All code compile and run on my old comupter.
I have 2 project in my solution than use typescript.
The first compile without problem.
The second one show error on compile but generate js on save.
I have installed vs 2013 update 5 then installed typescript 1.8.5.
I alsow have vs2015 installed.
After vs2015 was installed i have repair the typescript sdk.
They must have 2 different compiler setup and one in my project is not set correctly.
I have dig into the csproj and compare the 2 project but did not find missing/different parameter for typescript ....
It's like it dont take the new version. I get syntax errors in code i know it compile.
if someone had this problem, please help me.
p.s excuse me for my bad english, im french ...
UPDATE: Exemple of code dont compile
public doSomething(errorCallBack?: (failCallback1?: JQueryPromiseCallback<any> | JQueryPromiseCallback<any>[], ...failCallbacksN: Array<JQueryPromiseCallback<any> | JQueryPromiseCallback<any>[]>) => void)
{}
Error :
Error 218 Build: ',' expected.

A reduced sample code that fails to compile:
class Foo {
public doSomething(errorCallBack?: (failCallback1?: any, ...failCallbacksN: Array<any>[]>) => void)
{ }
}
You have major syntax errors in ...failCallbacksN: Array<any>[]>. You need something like ...failCallbacksN: Array<any> e.g.:
class Foo {
public doSomething(errorCallBack?: (failCallback1?: any, ...failCallbacksN: Array<any>) => void)
{ }
}
but js get generated
This is by design. Valid JavaScript will always generate valid TypeScript (even in the presence of errors). The types are considered invisible to the emitter in TypeScript so even in the presence of type errors TypeScript will try and do graceful recovery and generate JavaScript.

I have found than visual studio IDE was using 1.8.9 and the compiler was 1.0. This is why i had such compilation errors.
when i used "tsc -v" command in vs2013 command prompt, it show 1.0.
when i use "where tsc" it show only directory for 1.0 and not the 1.8.9.
so, i have replaced the 1.0 content with 1.8.9 . I dont use 1.0.
Now i have a 1.0 directory wish have 1.8.9 in it.
I think this is not the way it's supposed to be, but i need it to work.
It have a .target file i can modify, but i dont wish to do that.

go-swagger restapi/configure_todo_list.go - api.TodoGetHandler undefined error

I am a newbie in go and go-swagger. I am following steps in Simple Server tutorial in goswagger.io.
I am using Ubuntu 18.04, swagger v0.25.0 and go 1.15.6.
Following the same steps, there are a few differences of the files generated. For instance, goswagger.io's has find_todos_okbody.go and get_okbody.go in models but mine does not. Why is that so?
Link to screenshot of my generated files vs
Link to screenshot of generated files by swagger.io
Starting the server as written in the tutorial go install ./cmd/todo-list-server/ gives me the following error. Can anyone please help with this?
# my_folder/swagger-todo-list/restapi
restapi/configure_todo_list.go:41:8: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
restapi/configure_todo_list.go:42:6: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
The first step in goswagger.io todo-list is swagger init spec .... Which directory should I run this command in? I ran it in a newly created folder in my home directory. However, from the page, it shows the path to be ~/go/src/github.com/go-swagger/go-swagger/examples/tutorials/todo-list. I am not sure whether I should use go get ..., git clone ... or create those folders. Can someone advise me?
Thanks.
This is likely the documentation lagging behind the version of the code that you are running. As long as it compiles, the specific files the tool generates isn't so crucial.
This is a compilation error. When you do go install foo it will try to build the foo package as an executable and then move that to your GOPATH/bin directory. It seems that the generated code in restapi/configure_todo_list.go isn't correct for the operations code generated.
All you need to run this tutorial yourself is an empty directory and the swagger tool (not its source code). You run the commands from the root of this empty project. In order not to run into GOPATH problems I would initialise a module with go mod init todo-list-example before doing anything else.
Note that while the todo-list example code exists inside the go-swagger source, it's there just for documenting example usage and output.
What I would advice for #2 is to make sure you're using a properly released version of go-swagger, rather than installing from the latest commit (which happens when you just do a go get), as I have found that to be occasionally unstable.
Next, re-generate the entire server, but make sure you also regenerate restapi/configure_todo_list.go by passing --regenerate-configureapi to your swagger generate call. This file isn't always refreshed because you're meant to modify it to configure your app, and if you changed versions of the tool it may be different and incompatible.
If after that you still get the compilation error, it may be worth submitting a bug report at https://github.com/go-swagger/go-swagger/issues.
Thanks #EzequielMuns. The errors in #2 went away after I ran go get - u -f ./... as stated in
...
For this generation to compile you need to have some packages in your GOPATH:
* github.com/go-openapi/runtime
* github.com/jessevdk/go-flags
You can get these now with: go get -u -f ./...
I think it's an error of swagger code generation. You can do as folloing to fix this:
delete file configure_todo_list.go;
regenerate code.
# swagger generate server -A todo-list -f ./swagger.yml
Then, you can run command go install ./cmd/todo-list-server/, it will succeed.

'Gulpfile.js - failed to load See output' but output does not show any error information

I am trying to use gulp to copy some JS/CSS from node_modules to wwwroot in an ASP.Net core app.
I have what I thought was a fairly simple gulpfile.js
var gulp = require('gulp');
gulp.task('copy-files', function () {
var assets = {
js: [
'./node_modules/bootstrap/dist/js/bootstrap.js'
],
css: [
'./node_modules/bootstrap/dist/css/bootstrap.css'
]
};
_(assets).forEach(function (assets, type) {
gulp.src(assets).pipe(gulp.dest('./wwwroot/' + type));
});
});
However, when I look at the VS Task Runner, it just shows an error:
But the output window is empty:
How can I get more information about the error?
This answer here worked for me.
Moved up the $(PATH) location above everything. As I did not have (DevEnvDir)|Extensions\Microsoft\Web Tools\External location as mentioned in the answer.
For VS 2015
Tools > Options > Projects and Solutions > External Web Tools
For VS 2017
Tools > Options > Projects and Solutions > Web Package Management > External Web Tools
The problem is not related to path, but actually there must be some problem with gulp file itself either syntax error or some package is missing which unfortunately visual studio does not show that specific error but generic error what you see in task runner "failed to load". And the right way to see the errors is
Open the command prompt (preferably in admin mode, this is what i did).
Goto the same location where gulp file is located.
Run the task through following command example --> gulp default
If there is any error like package is missing, it will show you, fix those issues.
After all errors are fixed, then you will see that gulp task runs successfully.
Go back to visual studio, task runner, and click on refresh (left top button), and it will show you all tasks.
screenshot?
I'm not sure why but opening a cmd prompt at the directory containing gulpfile.js and running npm install has fixed it.
Perhaps someone wiser than I can explain why.
In Output window, make sure you select Task Runner Explorer for Show output from option. This was my problem why I didn't see the error logs from gulpfile. A rookie mistake.
I'm using Visual Studio Community 2019 Version 16.5.4.
I had the same problem and found the answer in the next link:
https://developercommunity.visualstudio.com/content/problem/961170/gulpfile-fails-to-load-after-upgrading-to-vs2019-1.html
Gulp uses node.js but it is important the version to be compatible. I've tried few versions and at the end version 0.12.7 works for me. But had to place absolute path to the place where that node version is installed in VS
Tools > Options > Projects and Solutions > External Web Tools
and move the path to the top. Placing the Path in environment variables and moving $(PATH) to the top didn't help in my case.

'a is undefined' when compiling a cljs prj with an NPM module under :prod profile

I followed this howto: http://blob.tomerweller.com/reagent-import-react-components-from-npm and it worked great. I even managed to use one of my own NPM module on top of this example app of re-frame: https://github.com/Day8/re-frame/tree/master/examples/simple/
Starting the resulting app with:
lein clean && lein figwheel
everything works ok, but when I do:
lein do clean, with-profile prod compile
I get a TypeError: a is undefined. Any idea to fix this?
Let me provide you with the code: the bad commit is here,
while both :dev and :prod profiles work OK at this just previous commit.
Update: I managed to fix the compiled version like this (see the commit):
return d.c?d.c(c,v,w):d.call(null,c,v,w)}}(G,r,b,c,d,e)),I=dw(G);rf.b?: […]
};w.b=v;w.c=f;return w}()}(c,d,e,f))};hf.b(ow,ik);hf.b(ow,bp);hf.b(ow,To); […]
function nx(a){var b=window.deps["react-mathjax"],
- c=window.deps.clubexpr.kf;
+ c=window.deps.clubexpr.renderLispAsLaTeX;
return new U(null,3,5,V,[Vj,b.Context,new U(null,4,null)}
function Wv(){return function(a){return function(){return new U(null,6,5,V,[…]
This seems to me a compilation misconfiguration or bug.
Update 2: my code compiles OK if I set :optimizations to :simple (was :advanced). See the cljs compiler doc about this option.
Thanks.
The code that is failing is here.
It looks like you might need to provide externs for clubexpr, so that the Closure Compiler knows not to rewrite renderLispAsLatex as kf. When compiling under :simple, the Closure Compiler doesn't rewrite function names, so this problem wouldn't show up.
As a side note, you probably shouldn't use aget to get objects from the window, aget is designed for array access only. To get objects, you should use goog.object/get. See this post on Checked Array Access for more info on this.

WebEssentials tslint custom rules

I have a tslint.json file in my solution directory and I'm trying to create a custom rule following the guidelines on https://www.npmjs.com/package/tslint
I have created a "nonImportsRule.ts", have copied the code from the link and have added "no-imports": true to my tslint.json file however the rule is not being picked up.
The guide says that a rulesDirectory needs to be specified, but I have no idea where this should be configured?
Also - is it possible to setup Web Essentials to break the build if tslint rules are violated?
I had a same kind of a problem. I wanted to use the TSLint extensions, tslint-microsoft-contrib and codelyzer, together with Web Analyzer. This did not work. The first step to figure out why was to make an adaptation in server.js which can be found in C:\Users\[User]\AppData\Local\Temp\WebAnalyzer1.7.75. I changed the TSLint function into:
tslint: function (configFile, files) {
// Try catch tslint errors
try {
var tslint = require("tslint");
var options = {
formatter: "json",
configuration: JSON.parse(fs.readFileSync(configFile, "utf8").trim())
};
var results = [];
for (var i = 0; i < files.length; i++) {
var file = files[i];
var ll = new tslint(file, fs.readFileSync(file, "utf8"), options);
results = results.concat(JSON.parse(ll.lint().output));
}
} catch(error) {
// Return tslint error to visual studio so we can get some ideas for counter measures.
var result = JSON.parse('[{"endPosition": {"character": 0,"line": 0,"position": 0},"failure": "INSTALL ERROR","name": "/","ruleName": "INSTALL ERROR","startPosition": {"character": 0,"line": 0,"position": 0}}]');
result[0].failure = error.message;
return result;
}
return results;
},
The alternation resulted in error feedback in the visual studio error list when I run the Web Analyzer. Do not forget to force a new instance of node.exe with the task manager after you have applied the alternation. The feedback leaded, for my particular situation, to the following installation of npm packages in the following directories:
Packages:
"codelyzer": "0.0.12"
"tslint": "^3.7.3"
"tslint-microsoft-contrib": "^2.0.2"
"typescript": "^1.8.9"
Directories:
C:\Users\[User]\AppData\Local\Temp\WebAnalyzer1.7.75
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
After this, Web Analyzer was able to use the same tslint rules as my grunt task. Hopefully a newer version of Web Analyzer will solve my problems more elegantly.
Okay, i'm not using Web Essentials extension but Web Analyzer : https://visualstudiogallery.msdn.microsoft.com/6edc26d4-47d8-4987-82ee-7c820d79be1d
So i won't be able to answer on this question 100%, but i want to summarize here my experience with custom tslint rules. First of all, what is not completely clear from documentation is that the whole thing depends on node.js.
So first of all you need to install node js. This will give you npm command to your command line.
After install with npm tslint and typescript. https://github.com/palantir/tslint here are examples. These will create files in : "c:\Users[Username]\AppData\Roaming\npm\node_modules"
Go into "c:\Users[Username]\AppData\Roaming\npm\node_modules\tslint\lib\rules\". Create here noImportRule.ts. Copy the following content:
import * as ts from "typescript";
import * as Lint from "../lint";
export class Rule extends Lint.Rules.AbstractRule {
public static FAILURE_STRING = "import statement forbidden EDE";
public apply(sourceFile: ts.SourceFile): Lint.RuleFailure[] {
return this.applyWithWalker(new NoImportsWalker(sourceFile, this.getOptions()));
}
}
// The walker takes care of all the work.
class NoImportsWalker extends Lint.RuleWalker {
public visitImportDeclaration(node: ts.ImportDeclaration) {
// create a failure at the current position
this.addFailure(this.createFailure(node.getStart(), node.getWidth(), Rule.FAILURE_STRING));
// call the base version of this visitor to actually parse this node
super.visitImportDeclaration(node);
}
}
Note that in the example import lint is not given with relative path that won't work with this approach.
4. Fire the command : "tsc -m commonjs --noImplicitAny .\noImportsRule.ts". This will compile your custom rule's ts. You will get bunch of compilation errors, such as: ../enableDisableRules.d.ts(1,21): error TS2307: Cannot find module 'typescript'. That's a good question why are these thrown, but forget about them, js file will be generated anyway.
5. Put "no-imports": true to your tslint.json(for now this should be custom one). With this command from command line:
tslint -c 'sample.tslint.json' test.ts
you will get:
test.ts[1, 1]: import statement forbidden. So you made the custom rule working!!! :)
That's all for working from command line. In addition I made custom rules working with WebAnalyzer, at least temporary.
I needed to copy my custom rule's files here:
c:\Users[Username]\AppData\Local\Temp\WebAnalyzer1.6.65\node_modules\tslint\lib\rules\ and of course configure WebAnalyzer tslint.json to include custom rules.
I have no idea how Web Essentials extension makes this whole thing working with tslint, but i guess some way similar :). Somewhere there should be a folder (node_modules\tslint\lib\rules) with rules what tslint uses. There you need to copy your custom ones.
Of course the most elegant solution would be to modify Web Essentials extension itself and make the tslint's custom rules directory configurable from visual studio. (so my solution is just a workaround)
Here is my custom rule example in the visual studio warning's list:

Why does command "tsc file.ts" give no output and not produce a js file?

I have just started work on a project with some typescript code, and I'm trying to compile the .ts files to .js files from within Linux Mint, but it's not working as I'd expect.
There is a Makefile, but it's not working. Running make returns an error:
tsc --noImplicitAny --noEmitOnError --out client/welcome.js client/welcome.ts
make: *** [client/welcome.js] Error 1
I have also tried creating an example typescript file greeter.ts (as per this official tutorial) containing:
function greeter(person) {
return "Hello, " + person;
}
var user = "Jane User";
document.body.innerHTML = greeter(user);
and tried compiling the ts file to javascript with the command (as per the same tutorial) tsc greeter.ts however the command completes with no output, and no .js file has been created.
I haven't previously worked with typescript at all, and though I've used Makefile's before I don't know much about them either, so I'm hoping it's something really obvious!
I encountered this problem because I had the following line in my tsconfig.json:
"noEmit": true
It worked after removing it.
--noEmitOnError
This means that if there is an error detected no js will be generated. I highly recommend not using this option (Changes a major benefit of why typescript)

Check your tsc version. The code you provided works fine with 1.6:
Update
The --version command should work at the very least. See below:
