Actual behavior:
Very slow, gulp does:
[21:17:49] Finished 'compileSources' after 9.31 s
... change a file ...
[21:18:04] Finished 'compileSources' after 7.4 s
Your gulpfile:
const ts = require('gulp-typescript');
const tsProject = ts.createProject('tsconfig.json');
gulp.task('compileSources', () =>
tsProject.src()
.pipe(tsProject())
.js.pipe(gulp.dest('artifacts'))
);tsconfig.json
Include your tsconfig, if related to this issue.
