A workaround is to do a native import()
inside eval()
(to avoid the compiler handling it):
// If using typescript, type-only `import` will be fine
import type {Node} from 'yoga-layout'
function getYoga() {
const [yoga, setYoga] = createSignal<typeof import('yoga-layout')>()
const promise = eval("import('https://unpkg.com/yoga-layout@3.1.0/dist/src/index.js')")
promise.then(setYoga)
return yoga
}
// ...
const yoga = getYoga()
createEffect(() => {
const yogaModule = yoga()
if (!yogaModule) return
const {default: Yoga, Direction, FlexDirection, Gutter} = yogaModule
// ... use yoga as before ...
})
This seems somehow related to the issue of effects not running. https://discord.com/channels/722131463138705510/1275456175462420614
In the above case, I was able to cause effects not to run due to the presence of await import()
inside of components, and was able to workaround by setting ssr:false
in app.config (only for dev mode, prod mode is not working at all), although maybe this is just a secondary effect of the real issue.
Looks like server.esbuild.options.target
is in fact passed to Nitro. So Nitro needs an update so that it will handle node_modules
?
I took Nitro 2.9.7 for a spin, looks like it supports top-level await out of the box.
I forced nitropack version 2.9.7 in the Solid Start app, but I still get the same top-level await error for yoga-layout when running npm run dev
.
The fix in
got rid of the need to use await import()
for the lume
package, cleaning up imports in several modules.
However the issue of node_modules
not being handled by the dev/build tooling still persists with yoga-layout
, so now I'm down to a single file that has an await import()
, currently looking like this:
// This is not working yet (https://github.com/solidjs/solid-start/issues/1614), so we import with conditional await import()
// import Yoga, {Direction, FlexDirection, Gutter, Wrap, Edge, Justify, Align} from 'yoga-layout'
let Yoga: typeof import('yoga-layout').default
let Direction: typeof import('yoga-layout').Direction
let FlexDirection: typeof import('yoga-layout').FlexDirection
let Gutter: typeof import('yoga-layout').Gutter
let Wrap: typeof import('yoga-layout').Wrap
let Edge: typeof import('yoga-layout').Edge
let Justify: typeof import('yoga-layout').Justify
let Align: typeof import('yoga-layout').Align
if (globalThis.window?.document) {
;({
default: Yoga,
Direction,
FlexDirection,
Gutter,
Wrap,
Edge,
Justify,
Align,
} = (await import('https://unpkg.com/yoga-layout@3.1.0/dist/src/index.js')) as typeof import('yoga-layout'))
}
// ...
The await import('https://unpkg.com/yoga-layout@3.1.0/dist/src/index.js')
with an actual URL causes the build to avoid transforming the import()
expression, so the app will import from unpkg.com in the browser.
Duplicates
Latest version
Current behavior 😯
Use
npm create solid
to make abasic
app, then put a top-levelawait something
in a module, and you'll get an error duringnpm run build
like so:Expected behavior 🤔
It should just work out of the box. It works in all JS runtimes and browsers out of the box.
Steps to reproduce 🕹
Problem 1:
Steps:
npm create solid
await something()
at the top level of a modulenpm run build
The error will look something like this:
To fix the problem, the following will not work:
but one would think that it would, because this is what we see when we look at intellisense:
In the screenshot we can see that the auto-completion in VS Code will give us a strong hint that setting this option will work. But that's not the case (when it comes to application code).
Instead, we must set a different option of the same name at another location, which is not so obvious considering that Vite uses esbuild and one may very well assume the vite esbuild config will do the trick:
Problem 2:
If you import a library from npm that has top-level
await
, there's no way to make it work. Setting either of the two options above will not work!Steps:
npm create solid
npm install yoga-layout
npm run dev
The error will look something like this,
which as you can imagine is frustrating because
yoga-layout
is a 3rd-party library, and the neither of the twotarget
configs is helping.The error says my target environment is
chrome87
. Why is that, if I've specifiedesnext
, when is comes to the node_modules dependency?Context 🔦
All JS runtimes support top-level await natively for a long time now. Solid Start should too!
