Deno 1.15, the latest release of the JavaScript runtime positioned as a secure alternative to Node.js, features a new flag that makes it easier to run Node.js programs in Deno.
Deno 1.15 was published October 12. When the
1 | --compat |
flag is present, Deno will automatically set up Node global variables, such as
1 | process |
, and provide all built-in modules available in Node. Note that this flag currently requires
1 | –-unstable |
.
The version of
1 | –-compat |
in Deno 1.15 is just a first pass. More work will be put into improving compat mode in coming releases, moving toward Node emulation. According to Deno 1.15 release notes, std/node is a module that provides a compatibility layer for Node APIs, enabling developers to run a subset of Node programs in Deno. The release of std 0.111.0 updates the compatibility layer, adding desired modules including dns, http, and net, along with updates to the cryptocode module.
