Ionic 2 improved and now debuggable from WebStorm

How to debug Ionic 2 from within Webstorm

This post talks about the improvements in the latest version of Ionic…

http://blog.ionic.io/improvements-to-ionic-build-process/

And this explains how to set up debugging but doesn’t make it quite clear where to do one step…

http://blog.thecodecampus.de/setup-ionic-2-typescript-debugging-intellijwebstormjetbrains-ide/

The best way to prove it can work is to start from a new Ionic project. If you’ve got an existing project, skip to the end of this post.

C:\Samples> ionic start HelloIonicWebstorm –v2 tabs

(goes to make cup of tea…)

(mmm cold pizza! nom nom…)

cd HelloIonicWebstorm

ionic platform add browser

Run Webstorm, open c:\samples\HelloIonicWebstorm

Edit tsconfig.json and make sure there is a sourceMap line:

"moduleResolution": "node",
"sourceMap": true,
"target": "es5"

Edit package.json and add a config section with an ionic_source_map member:

{
 "name": "ionic-hello-world",

"author": "Ionic Framework",
 "homepage": "http://ionicframework.com/",
 "private": true,
"config":{
 "ionic_source_map":"source-map"
 },
 "scripts": {...

Run-Edit Configurations-Add-Phonegap/Cordova-

  • Name the configuration,
  • check your executable is ionic.cmd,
  • check working directory,
  • command should be serve
  • platform should be browser

Run the Ionic Serve configuration

Run-Edit Configurations-Add-Javascript Debug and

  • name it TypescriptDebug
  • URL should probably be localhost:8100 (the default ionic serve url)
  • click the folder for your src directory and Apply

Create a ngOnInit() method within home.ts and set a breakpoint at the end of that method:

Run the Ionic Serve (Run… Run… choose Ionic Serve)

Run Typescript debugging (Run… Debug… choose Typescript)

Check that “JetBrains IDE Support is debugging this browser”

You may have to close all your browser windows and retry.

Finally had a chance to read some of Josh Morony’s Ionic 2 blog posts which are very helpful, clear and short

If you have an  existing Ionic 2 project you will have to get your package.json and tsconfig.json up to the latest.

Re-read this post…

http://blog.ionic.io/improvements-to-ionic-build-process/

Copy package.json and tsconfig.json from your working new Ionic 2 project, or update the dependencies from here https://github.com/driftyco/ionic/blob/master/CHANGELOG.md#200-rc3-2016-11-17

Now delete the contents of node_modules in your project folder and

npm install

That will re-fetch the packages you need

INNER JOIN sys.schemas (NOLOCK) ON sys.objects.schema_id = sys.schemas.schema_id
WHERE
 sys.sql_modules.definition COLLATE SQL_Latin1_General_CP1_CI_AS LIKE '%PackagingId%' ESCAPE '\'

Jint joy: execute js from within c# #itsyourfoot

Just followed this SO answer to look at Jint on github. The project has plenty of current updates.

Imagine you have a WebAPI in C# and your client wants to select rows with a javascript filter. Well with Jint you can run arbitary code on the server. You must only use this power for good #itsyourfoot

[TestMethod]
 public void ScriptEngineShouldFilterRows()
 {
 //Loving https://github.com/sebastienros/jint/ !
 //install-package jint then...
 var engine = new Jint.Engine()
 .SetValue("log", new Action<object>(Console.WriteLine))
 ;

//get your json of objects e.g. from select * from cats for json row
 var json = @"[{""name"":""tom""},{""name"":""fritz""},{""name"":""felix""}]";
 //decide which cats you want
 var filter = "itm.canRead = itm.name.substring(0,1)=='t';";

//write a js function filterrows that takes the rows (as a string) 
//and returns the selected rows (as a string)
 var js = @"
 function filterrows(rows) { 
 var itms = JSON.parse(rows);
 var filtered = [];
 itms.forEach(function(itm){
 " + filter + @"
 if(itm.canRead){
 filtered.push(itm);
 }
 });
 return(JSON.stringify(filtered));
 };
 ";
//use the engine to call the function
 var v = engine.Execute(js)
 .Invoke("filterrows", json);
 //aagh got an exception. 
 //BUT there's a helpful error message that points you 
 //to the right row in your javascript...

//v now contains your selected rows

}
