[sasjs-dev]

For a SASjs Server target the streamed app is copied verbatim, so the <sasjs> tag keeps whatever appLoc the frontend was built with. Served from AppStream the app gets no appLoc from its URL either - so a deployment to any appLoc but the frontend's default has it calling services on the default one.

Reproduced on sas.4gl.io

Deployed a Data Controller estate to /Public/app/dc477 and clicked BROWSE on the deploy screen. With the browser instrumented, the request went to the default appLoc:

POST https://sas.4gl.io/SASjsApi/stp/execute/?_program=/Public/app/dc/services/admin/makedata

and came back with that appLoc's refusal, while /Public/app/dc477 had never been touched. The deployed file confirmed it:

/Public/app/dc477/services/web/index.html -> apploc="/Public/app/dc"

The change

createWebAppServices (the compile step that materialises the streamed app) already parses the index and rewrites the tag for Viya and SAS9 via updateSasjsTag. The SASjs branch now does the same, on the copy it has just made:

await copy(webSourcePathFull, destinationPath)

const copiedIndex = path.join(destinationPath, 'index.html')
const indexHtml = new jsdom.JSDOM(await readFile(copiedIndex))
const sasjsTags = getSasjsTags(indexHtml)

if (sasjsTags.length) {
  updateSasjsTag(sasjsTags[0], target)
  await fs.promises.writeFile(copiedIndex, indexHtml.serialize())
}

updateSasjsTag sets appLoc and serverType from the target, so the value deployed and the value the app calls cannot disagree.

Verification

• npx jest src/commands/web: 36 passing across the seven suites; the new case builds a web folder with appLoc="/Public/app/default", streams it to a SASjs target at /Public/app/AnotherLoc and asserts the copy carries the target's appLoc. It fails if the stamping is removed (checked).
• Prettier clean.
• End to end: with this build deployed to /Public/app/dc477, the served services/web/index.html carries apploc="/Public/app/dc477" and BROWSE on that deployment lists folders (DC620298, DC620385, DC627259) instead of calling the default appLoc.

Related but separate: #1554 (the worker script's own URL) - that one is about a stale worker serving a previous build's runtime.
