Typescript files not showing in Angular 2 CLI project using chrome web developer tools -


i have generated typescript project using angular2 cli (ember cli). using chromium web developer tools debug. have "enable javascript source maps" selected in developers tools settings. see .js files , .ts listed in sources view. however, .ts (typescript) files show empty when select them i.e can't find them.

screen print showing situation:

enter image description here

i can see text of .js files if select them.

the .ts files not copied dist directory, , seems problem me, i've seen examples elsewhere showing typical angular2 cli dist structures , not have .ts files either.

relevant portion of "tsconfig.json" showing have source mapping enabled:

 1   "compileonsave": false,                                                                               2   "compileroptions": {                                                                                  3     "declaration": false,                                                                               4     "emitdecoratormetadata": true,                                                                      5     "experimentaldecorators": true,                                                                     6     "maproot": "",                                                                                      7     "module": "system",                                                                                 8     "moduleresolution": "node",                                                                         9     "noemitonerror": true,                                                                             10     "noimplicitany": false,                                                                            11     "outdir": "../dist/",                                                                              12     "rootdir": ".",                                                                                    13     "sourcemap": true,                                                                                 14     "sourceroot": "/",                                                                                 15     "target": "es5"                                                                                    16   },

js.map files are produced , reside in dist directory next .js files.

example mapping file (portion):

{"version":3,"file":"app.js","sourceroot":"/","sources":["app.ts"],"names":[],"mappings":";;;;;;;;;;;;;yaga,mb

i've tried:
1) copying .ts files src dist.
2) various attempts @ editing app.js.map file manually e.g sourceroot , sources.

it's not quite clear "/" referring in js.map file: project's src dir or dist dir? if edit .js.map file have refresh browser pick on it?

i think basic problem it's looking ts files in src dir, , outside reach of browser (since it's located @ "../src").

chromium shows path ts file "http://localhost:4202/app/cpp-scenes.ts". when put .ts file there, no dice.

i don't know if js mapping problem, angular 2 problem, angular2 cli problem, or typescript problem.

it's real pain when console says "error in line 52 in blah.ts", can't jump there , put in breakpoint etc.

has else had luck getting source mapping working in angular2 cli project?

i able work. have to add angular cli src folder workspace, , have "map network resource" on 1 of .ts files.

note: example assumes case client , server running on same machine. if have situation client on windows machine, server running on linux example, on client machine have mount linux server source directory windows share , specify like

\\192.168.1.134\myshare\myproject\src\client

as workspace folder.

i had this, , while it's little more complicated, fundamentally works same local case

i took screen shots of entire process, it's easiest show these.

  1. select 1 of ts files resides under dist directory (that corresponds directory ng serve serving from), , select "add folder workspace":

screen 1

  1. select src/client folder: enter image description here

  2. say "allow" subsequent prompt allowing dev tools access src dir: enter image description here

  3. observe src folder listed under dev tools sources. can browse ts files (not 1 added), breakpoints set won't take effect until "establish mapping": enter image description here

  4. you can enable mapping shown in next 2 screen prints: enter image description here

select appropriate mapping , click on enable enter image description here

now can set breakpoint in .ts file , drill down on error messages .ts source.

the basic trick have add source ts file directory chrome manually, since files not under serving directory. mapping stays in effect until either manually remove (by right-clicking on .ts file , selecting "remove network mapping") or until close browser (it retain mapping on refreshes however)

Google AdWords and AdSense - A Dynamic Small Business Marketing Duo

Unless you have been living under a rock for the last year or so, you probably know that Google has become the king of the search engine hill. There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners.
