Optional compiler middleware
The optional compiler middleware enables advanced middleware usage such as implementing compilers as middleware or even composable compilers. @webtask/middleware-compiler
plays a fundamental role in enabling middleware functions and one of its core assumptions is that the underlying webtask script (located at req.webtaskContext.compiler.script
) is a string. It would be convenient to be able to reassign the webtask script to a compiled Function
object when implementing a compiler. Unfortunately, this breaks the assumption made by @webtask/middleware-compiler
(or even other userspace middleware functions) that it is safe to call nodejsCompiler
on req.webtaskContext.compiler.script
. This middleware decorates the nodejsCompiler
with optional compilation based on the type of the webtask script.
Usage
Set the
wt-node-dependencies
metadata property to the stringified JSON of an object having@webtask/middleware-compiler
and@webtask/optional-compiler-middleware
properties whose values are the latest version of the @webtask/middleware-compiler module and this module, respectively.{ "@webtask/middleware-compiler": "1.5.0", "@webtask/optional-compiler-middleware": "1.0.0" }
Set the
wt-compiler
metadata property on your webtask to@webtask/middleware-compiler
.Set (or add to) the
wt-middleware
metadata property of your webtask to contain a comma-separated list containing@webtask/optional-compiler-middleware
.Issue requests to your webtask
