VS2017 takes long time recompiling typescript on save
I've got an ASP.Net project with some TypeScript making use of D3/SignalR/Lodash via NPM @types.
Up until last week we were using VS2015 and there were no issues. I was very impressed with compilation times, actually, since my earlier sandbox environment was in Sublime and that took ~4 seconds to build. VS2015 seemed to do it near-instantly on save, so I was very happy with that.
Now we have upgraded to VS2017, and saving has become a huge problem. Saving takes 30+ seconds, as the TypeScript compiler now slowly goes through each of the type definition files (d3, lodash, signalR, etc.). Even if I make the tiniest change, like fixing a typo in a string, or change an int constant, it still takes 30+ seconds to recompile. Actually, I think it even recompiles even if I just press CTRL+S without even making any changes.
The status down the bottom is:
Generation of '[...]' complete. Remaining files still compiling.
I've looked this up already, and apparently "starting with VS2015" compile-on-save now requires a full recompilation. I don't know what's changed, but there is a MASSIVE difference since upgrading from VS2015 to VS2017.
Here is my tsconfig.json file:
{
"compileOnSave": true,
"compilerOptions": {
"noImplicitAny": true,
"removeComments": true,
"preserveConstEnums": true,
"alwaysStrict": true,
"out": /* out */,
"sourceMap": true
},
"files": [
/* files */
],
"exclude": [
"node_modules"
]
}
I recently added that exclude node_modules hoping it would fix the problem, but it doesn't seem to have made any difference.
Any ideas? Thanks.
Seems to be reported as an issue. It is under investigation at the moment. I have the same problem. Really annoying. https://developercommunity.visualstudio.com/content/problem/10762/typescript-background-compilation-too-often-causes.html
