I understand after this change, projects using melange with dune have to replace:

(melange.compile_flags :standard -bs-jsx 3)

with

(preprocess (pps reactjs-jsx-ppx))

right?

Also, should melc cli be updated to remove, or deprecate, the -bs-jsx flag? I believe it is useless now?

That's correct.

Yup, the flag is effectively useless now. I think we might be able to remove it entirely, since:

  • in dune integration projects (which we haven't shipped yet, so early adopters), your code wouldn't work until you use a preprocessing stanza
  • mel used to add the flag automatically, and people didn't use it

[new release] rescript-syntax, reactjs-jsx-ppx and melange (1.0.0)
ae6cea7 
CHANGES:

- melange: print an error message if `$MELANGELIB` is set to a directory that
  doesn't exist ([melange-re/melange#449](melange-re/melange#449))
- melange: fix bug where `--bs-module-name` didn't always affect generated JS
  file casing ([melange-re/melange#446](melange-re/melange#446))
- melange: fix bug where `-o output.js` didn't always write a JavaScript file
  ([melange-re/melange#454](melange-re/melange#454))
- melange: remove the `-bs-read-cmi` flag in favor of the builtin
  `-intf-suffix` flag, standard in OCaml
  ([melange-re/melange#458](melange-re/melange#458),
  [melange-re/melange#460](melange-re/melange#460))
- melange: return an actionable error message when no output is specified
  with `-impl` / `-intf`
  ([melange-re/melange#465](melange-re/melange#465),
  [melange-re/melange#466](melange-re/melange#466))
- melange: use `Object.prototype.hasOwnProperty` in the `Caml_obj` runtime
  ([melange-re/melange#469](melange-re/melange#469))
- melange: transform
  [`NonEscapeCharacter`](https://tc39.es/ecma262/#prod-NonEscapeCharacter)
  correctly in JS strings (those written using `{js|string here|js}`)
  ([melange-re/melange#469](melange-re/melange#469))
- melange: define `MELANGE` conditional compilation variable
  ([melange-re/melange#472](melange-re/melange#472))
- melange: Make `Pervasives` exactly match the `Stdlib` behavior
  ([melange-re/melange#476](melange-re/melange#476))
- melange: fix unbound error when trying to use `Printexc.exn_slot_id`
  ([melange-re/melange#482](melange-re/melange#482))
- melange: fix codegen issue accessing a nested module path that is also
  `include`d ([melange-re/melange#487](melange-re/melange#487))
- melange: preserve the correct command-line order for load path directories
  ([melange-re/melange#492](melange-re/melange#492))
- melange: respect the `-nostdlib` option; don't add stdlib / runtime to the
  load path in that case
  ([melange-re/melange#496](melange-re/melange#496))
- melange: build the Melange runtime / stdlib / runtime tests with the dune
  integration ([melange-re/melange#493](melange-re/melange#493)). Thus
  melange now requires Dune 3.8.
- melange: allow shadowing sub-modules of Stdlib in user projects
  ([melange-re/melange#512](melange-re/melange#512))
- melange, reactjs-jsx-ppx: introduce a `reactjs-jsx-ppx` package, remove its
  dependency from melange
  ([melange-re/melange#517](melange-re/melange#517))
- melange: remove the `--bs-jsx <version>` flag from `melc` now that
  `reactjs-jsx-ppx` is a separate package
  ([melange-re/melange#525](melange-re/melange#525))
- melange: add `melpp` executable to preprocess `#if` conditionals with the
  melange parser ([melange-re/melange#539](melange-re/melange#539))
- mel: delete the `mel` package. The dune integration is now the only
  officially supported workflow for orchestrating melange builds
  ([melange-re/melange#546](melange-re/melange#546))
- melange: Extract `melange.ppx` from the melange package. This preprocessing
  step interprets extensions such as `%bs.obj`, `%bs.raw`, `%bs.re`, etc.
  ([melange-re/melange#534](melange-re/melange#534))
- melange: allow installing melange in more OCaml versions and compiler
  switches. Melange now migrates binary AST to the version it understands
  ([melange-re/melange#548](melange-re/melange#548))
- melange: don't run anonymous args function from
  `[@@@bs.config {flags = [| ... |]}]` attributes
  ([melange-re/melange#554](melange-re/melange#554))
- melange: add `--preamble` flag to add a preamble to emitted JS. An example is
  `"use client";` in React Server Components, which needs to appear before
  imports ([melange-re/melange#545](melange-re/melange#545),
  [melange-re/melange#574](melange-re/melange#574))
- melange: turn off warning 20 (`ignore-extra-argument`) by default. This
  warning is rarely useful in Melange due to false positives when invoking
  functions defined with `%bs.raw`
  ([melange-re/melange#488](melange-re/melange#488),
