VS Code: "Breakpoint ignored because generated code not found" error
I have looked everywhere and I still have issue debugging TypeScript inside VS Code. I have read this thread but still I am not able to hit my breakpoints placed inside a TypeScript file, hitting the breakpoints in .js files all works fine.
So here is the simplest "hello world" project I have set up.
-
app.ts:
var message: string = "Hello World"; console.log(message);
-
tsconfig.json
{ "compilerOptions": { "target": "es5", "sourceMap": true } }
-
launch.json
{ "version": "0.2.0", "configurations": [ { "name": "Launch", "type": "node", "request": "launch", "program": "${workspaceRoot}/app.js", "stopOnEntry": false, "args": [], "cwd": "${workspaceRoot}", "preLaunchTask": null, "runtimeExecutable": null, "runtimeArgs": [ "--nolazy" ], "env": { "NODE_ENV": "development" }, "externalConsole": false, "sourceMaps": true, "outDir": null } ] }
I have generated the js.map files by running the tsc --sourcemap app.ts
command.
After all of those steps when I set a breakpoint on the console.log(message);
row and launch the program (F5) from the "Debug" tab that breakpoint is grayed out saying "Breakpoint ignored because generated code not found (source map problem?)." I attached a screenshot of what I am observing:
What am I missing?
Edit:
Hi, I am still stuck on this. I managed to make one sample project that was hitting the break points but after I tried to copy that project to a different location on my HDD the break points again became gray and were not hit. What I did different in this test project was to use inline sourcemaps by compiling the TypeScript files with tsc app.ts --inlinesourcemap
I uploaded the mentioned sample project to GitHub so you can take a look at it here.
Setting "outFiles" : ["${workspaceRoot}/compiled/**/*.js"]
solved the issue for me."outFiles"
value should match one set in tsconfig.json
for outDir
and mapRoot
which is ${workspaceRoot}
in your case, so try "outFiles": "${workspaceRoot}/**/*.js"
Here are my tsconfig.json
{
"compilerOptions": {
"module": "commonjs",
"noImplicitAny": true,
"removeComments": true,
"preserveConstEnums": true,
"sourceMap": true,
"target": "es6",
"outFiles": ["${workspaceRoot}/compiled/**/*.js"],
"mapRoot": "compiled"
},
"include": [
"app/**/*",
"typings/index.d.ts"
],
"exclude": [
"node_modules",
"**/*.spec.ts"
]
}
and launch.json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"program": "${workspaceRoot}/compiled/app.js",
"cwd": "${workspaceRoot}",
"outDir": "${workspaceRoot}/compiled",
"sourceMaps": true
}
]
}
Here is small project, where you may see all parameters set https://github.com/v-andrew/ts-template
I came across this question while looking for a solution to a similar problem that I was having. Despite being different from OP's problem, it might help others.
Context: I was following the Visual Studio Code HelloWorld example and found myself unable to stop on break points.
I solved my problem by changing .vscode/launch.json
so that "sourceMaps": true
attribute under the Launch configuration was set (it starts default on false).
