It would be really nice to have the ability to not fail on type errors during dts generation.

For example, add the ability to force set "noEmitOnError": false

Context:

  • we have a lot of type-errors during d.ts generation only but these errors don't affect the result d.ts file.

Right now the noEmitOnError: true overrides the one passed by a user:

 ...compilerOptions,
noEmitOnError: true,

tsup/src/rollup.ts

Lines 106 to 123 in 92ee842

plugins: [
tsupCleanPlugin,
tsResolveOptions && tsResolvePlugin(tsResolveOptions),
jsonPlugin(),
ignoreFiles,
dtsPlugin.default({
tsconfig: options.tsconfig,
compilerOptions: {
...compilerOptions,
baseUrl: compilerOptions.baseUrl || '.',
// Ensure ".d.ts" modules are generated
declaration: true,
// Skip ".js" generation
noEmit: false,
emitDeclarationOnly: true,
// Skip code generation when error occurs
noEmitOnError: true,
// Avoid extra work
