I think having an inline module format would help make the composition of build tools much easier.
Right now we have an ecosystem where everyone builds libraries into bundles using tools like Parcel, Rollup, Browserify, and Webpack. These create output which get recursively pulled into similar bundles. The problem is that the operation of merging files into bundles destroys static information we have with individual files. So optimizing compilers have difficulty doing code elimination (often called "tree shaking" in the community) across bundles. If we had a definition format for these bundlers to compile to which didn't destroy all the static information we have in separate files, we could build better optimizing compilers around them. I would hope that such a format would also allow engines to optimize the parsing of these inline modules (deferring most of the work until modules are actually loaded). There is other efforts in a similar space such was the webpackage format: https://github.com/WICG/webpackage/blob/master/explainer.md On Tue, Jun 19, 2018 at 11:23 AM, Andrea Giammarchi < andrea.giammar...@gmail.com> wrote: > we need to go deeper ... > > ```js > (async () => { > > const {getPersonType} = await import(`data:application/javascript, > export function getPersonType(person) { > switch (person) { > case 'Teacher': return 'A teacher'; > case 'Director': return 'A director'; > } > } > `) > > console.log( > getPersonType('Teacher') > ); > > })(); > ``` > > 💩 > > > > On Tue, Jun 19, 2018 at 12:10 AM, Darien Valentine <valentin...@gmail.com> > wrote: > >> ``` >> import getPersonType from 'data:text/javascript,\ >> export default function getPersonType(person) {\ >> switch (person) {\ >> case \'Teacher\': return \'A teacher\';\ >> case \'Director\': return \'A director\';\ >> }\ >> }'; >> ``` >> >> okay, not a serious suggestion, but it does technically work :) >> >> _______________________________________________ >> es-discuss mailing list >> es-discuss@mozilla.org >> https://mail.mozilla.org/listinfo/es-discuss >> >> > > _______________________________________________ > es-discuss mailing list > es-discuss@mozilla.org > https://mail.mozilla.org/listinfo/es-discuss > >
