REQUEST: Support for cross-platform SEA generation #94
Comments
Wouldn't it bloat the main NodeJS codebase and the distribution binary file? It will basically have to include O(n^2) instructions for all supported platform pairs. |
@GabenGar I don't know how |
They did it by creating their own binaries which had to be constantly patched to keep up with upstream nodejs binary. Hence why it was unsustainable and therefore archived now. |
Currently, cross-platform SEA generation is possible (as in, if you download executables for different platforms from the official source, generate one blob using an executable of your current platform, and inject the same blob into executables of different platforms, it still works and there's not much preventing it from working) unless you use the code cache or snapshot options (as those are platform-specific). It's more or less an undocumented feature at this point. It has been reported that it works nodejs/node#52420 (comment) - the injection would be based on executable format which can be done on even a platform that don't typically run that format, and the preparation blob layout is mostly the same across platform (again, unless you use code cache or snapshot) modulo endianness differences. |
So it's possible to use this feature but it's more or less an undocumented feature and has significant limitations. This part is understood. The request I filed is to make it user friendly and, at the minimum, better documented. It would also be nice to remove the requirement to have all the code in one file which, again, increases the barrier to usage. It's the difference between a feature that sort of works and only for 10% of the user base and one that is extremely useful and adds value to your product. Beyond that comment, I can't pretend to know your priorities, deadlines, and resource contentions. But it's a bit disturbing that you will not even acknowledge the difficulty, to a semi-experienced user, of creating a single-executable application without a lot of effort. |
Discussed in #89

We have been using
pkg
for crating SEAs. One of the great features ofpkg
is its support for generating SEAs for a variety of target OSes (for example, create a Linux executable from a Windows workstation). It does not seem that NodeJS's SEA capability supports this. Is it possible to add as a feature?The text was updated successfully, but these errors were encountered:
