Brewpage Publish

brewpage-publish

Publish content to brewpage.app — free instant hosting for HTML pages, JSON documents, files, and multi-file sites. No sign-up required.

Workflow

Step 1: Parse Arguments

Extract from $ARGUMENTS:

• --ttl N → TTL in days (default: 15)
• --entry <filename> → entry file for SITE uploads (default: auto-detect)
• Remaining text → content_arg

Step 2: Detect Content Type

Mode rule: directory/ZIP → SITE. Single file → FILE. POST /api/sites accepts ONLY a multipart archive=@file.zip — there is no raw-folder upload, so a directory is auto-zipped on the fly (the robust default; archive sealing keeps relative paths intact). Stats per type — SITE (dir): HTML count, total size, entry file. SITE (ZIP): file size, entry override. FILE: size + MIME via file --mime-type -b. TEXT/JSON: char count.

Step 3: Show Pre-Publish Stats

For HTML/JSON/FILE:

Content:  <type description> · <size> · <api endpoint>
TTL:      <N> days

For SITE: detect entry file using priority: 1) --entry flag, 2) index.html exists, 3) first .html file alphabetically.

Built-static guard (run BEFORE zipping). Publish BUILT output, never project sources:

• If the directory contains no .html file at all → FAIL with an explicit error: "No .html found — build the site first, then point at the build output directory." Do not guess an entry.
• If the directory looks like un-built sources (has package.json + src/ but no top-level .html) → warn and ask the user to point at the build output instead (dist/, build/, out/, _site/, or public/). Do not zip the source tree.

Content:  site · <N> files · <total_size> · POST /api/sites
Entry:    <entry_file>
TTL:      <N> days

Step 4: Ask Namespace

Use AskUserQuestion:

Namespace determines the URL prefix and gallery visibility on brewpage.app.

Options:
1) public — visible in gallery (default)
2) {auto-suggested 6-8 char slug}
3) Enter custom namespace
4) Skip → use public

Reply with a number or your custom namespace (alphanumeric, 3-32 chars).

Auto-suggest: generate a meaningful short slug (3-16 chars, lowercase alphanumeric + hyphens) from content context:

• File → topic/purpose of the file (e.g. api-docs, login-page, report-q2)
• Text/HTML → main subject or title (e.g. pricing, team-intro, changelog)
• JSON → data type or schema name (e.g. user-config, metrics)
• Fallback → project name or directory name if content is ambiguous Never use random strings or truncated filenames — the slug should be human-readable and describe what's being published.

Resolution:

• 1, 4, or empty → public
• 2 → suggested slug
• 3 or any other string → use as-is

Step 5: Ask Password

Use AskUserQuestion:

Password protection (if set, page is hidden from gallery):

Options:
1) No password (default)
2) Random: {generated 6-char password, e.g. "kx7p2m"}
3) Enter custom password (min 4 chars)
4) Skip → no password

Reply with a number or your custom password.

Generate random password EXECUTE using Bash tool:

LC_ALL=C tr -dc 'a-z0-9' < /dev/urandom | head -c6 2>/dev/null

Resolution:

• 1, 4, or empty → no password
• 2 → use generated random password
• 3 or custom text → use as-is

Step 6: Publish and Save Token (secure)

SECURITY: The ownerToken MUST NEVER appear in conversation output. The bash blocks below handle curl + token parsing + history save atomically; the LLM sees only the URL. Each block sets PASS_H first (empty array when no password) and uses "${PASS_H[@]}" quoted — passwords are never string-interpolated into the command. The site-dir zip excludes (.git/, .env*, etc.) are also a secret-leak safeguard — they keep credentials and VCS data out of the published archive.

6a. Init history file (run once, before the publish block) — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
if [ ! -f "$HISTORY_FILE" ]; then
  mkdir -p "$(dirname "$HISTORY_FILE")"
  cat > "$HISTORY_FILE" <<'HEADER'
# brewpage.app — Published Pages

> PRIVATE FILE — keep this out of version control and never share it.
> Owner tokens allow delete (no in-place PUT for sites; html/json/kv support PUT).
> Delete html/json/kv: `curl -s -X DELETE "https://brewpage.app/api/{ns}/{id}" -H "X-Owner-Token: TOKEN"`
> Delete site:         `curl -s -X DELETE "https://brewpage.app/api/sites/{ns}/{id}" -H "X-Owner-Token: TOKEN"`

| Date | URL | Owner Token | TTL | Type |
|------|-----|-------------|-----|------|
HEADER
fi

Then run ONE of the following publish blocks based on detected type. Each assumes HISTORY_FILE already exists from 6a.

HTML/Markdown text — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
CONTENT=$(cat <<'BREWPAGE_EOF'
{content}
BREWPAGE_EOF
)
PAYLOAD=$(jq -n --arg c "$CONTENT" '{content: $c}')
PASS_H=()
[ -n "$PASSWORD" ] && PASS_H=(-H "X-Password: $PASSWORD")
RESPONSE=$(curl -s -X POST "https://brewpage.app/api/html?ns={ns}&ttl={days}&format=markdown" \
  -H "Content-Type: application/json" \
  "${PASS_H[@]}" \
  -d "$PAYLOAD")

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d | html |" >> "$HISTORY_FILE"
  echo "OK $URL"
else
  echo "FAILED: $RESPONSE"
fi

JSON — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
PASS_H=()
[ -n "$PASSWORD" ] && PASS_H=(-H "X-Password: $PASSWORD")
RESPONSE=$(curl -s -X POST "https://brewpage.app/api/json?ns={ns}&ttl={days}" \
  -H "Content-Type: application/json" \
  "${PASS_H[@]}" \
  -d '{original_json}')

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d | json |" >> "$HISTORY_FILE"
  echo "OK $URL"
else
  echo "FAILED: $RESPONSE"
fi

File — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
PASS_H=()
[ -n "$PASSWORD" ] && PASS_H=(-H "X-Password: $PASSWORD")
RESPONSE=$(curl -s -X POST "https://brewpage.app/api/files?ns={ns}&ttl={days}" \
  "${PASS_H[@]}" \
  -F "file=@/absolute/path/to/file")

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d | file |" >> "$HISTORY_FILE"
  echo "OK $URL"
else
  echo "FAILED: $RESPONSE"
fi

Site (directory) — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
PASS_H=()
[ -n "$PASSWORD" ] && PASS_H=(-H "X-Password: $PASSWORD")
TMPZIP=$(mktemp /tmp/brewpage-site-XXXXXX.zip)
# Exclude VCS, secrets, deps, editor + OS junk and sourcemaps — publish only built static assets.
(cd "{directory_path}" && zip -r "$TMPZIP" . -x '.git/*' '*/.git/*' '.env' '.env.*' '*/.env' '*/.env.*' 'node_modules/*' '*/node_modules/*' '.DS_Store' '*/.DS_Store' 'Thumbs.db' '.idea/*' '*/.idea/*' '.vscode/*' '*/.vscode/*' '.cache/*' '*/.cache/*' '*.map' '*.log')
RESPONSE=$(curl -s -X POST "https://brewpage.app/api/sites?ns={ns}&ttl={days}&entry={entry}" \
  -H "User-Agent: ClaudeCode/1.0" \
  "${PASS_H[@]}" \
  -F "archive=@$TMPZIP")
rm -f "$TMPZIP"

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
URL="${URL%/}"  # strip any trailing slash — /public/<id>/ routes to brewpage landing
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')
FCOUNT=$(echo "$RESPONSE" | jq -r '.fileCount // "?"')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d | site ($FCOUNT files) |" >> "$HISTORY_FILE"
  echo "OK $URL | Files: $FCOUNT"
else
  echo "FAILED: $RESPONSE"
fi

Site (ZIP file) — EXECUTE using Bash tool:

HISTORY_FILE=".claude/brewpage-history.md"
PASS_H=()
[ -n "$PASSWORD" ] && PASS_H=(-H "X-Password: $PASSWORD")
RESPONSE=$(curl -s -X POST "https://brewpage.app/api/sites?ns={ns}&ttl={days}&entry={entry}" \
  -H "User-Agent: ClaudeCode/1.0" \
  "${PASS_H[@]}" \
  -F "archive=@{zip_file_path}")

URL=$(echo "$RESPONSE" | jq -r '.link // empty')
URL="${URL%/}"  # strip any trailing slash — /public/<id>/ routes to brewpage landing
TOKEN=$(echo "$RESPONSE" | jq -r '.ownerToken // empty')
FCOUNT=$(echo "$RESPONSE" | jq -r '.fileCount // "?"')

if [ -n "$URL" ]; then
  [ -n "$TOKEN" ] && echo "| $(date '+%Y-%m-%d %H:%M') | [$URL]($URL) | \`$TOKEN\` | {ttl}d | site ($FCOUNT files) |" >> "$HISTORY_FILE"
  echo "OK $URL | Files: $FCOUNT"
else
  echo "FAILED: $RESPONSE"
fi

Step 7: Output Result

Success (bash printed OK {url}):

Published: {url from bash output}
Owner token saved to .claude/brewpage-history.md

Success for SITE (bash printed OK {url} | Files: {count}):

Published site: {url from bash output}
Entry: {entry_file} | Files: {count}
Owner token saved to .claude/brewpage-history.md

⚠ Share the URL exactly as printed — DO NOT append a trailing slash.
  brewpage.app routes "/public/<id>/" to its own landing page, and the
  redirect that saves the no-slash form does not fire for the slash-dir form.

NEVER print the ownerToken in conversation. The token lives only in the history file.

Error (bash printed FAILED: ...):

Publish failed.

Notes

• Always use absolute file paths with curl -F "file=@...".
• Use jq -n --arg c "$CONTENT" '{content: $c}' to safely encode text content. format is a query param, not a body field — /api/html ignores any format key inside the JSON body and reads only ?format= from the URL. Wrong location = server applies default html and stores your markdown as raw text.
• TTL default is 15 days. Namespace must be alphanumeric (3-32 chars), default public.
• To delete a published page, find the owner token in .claude/brewpage-history.md and use the delete command shown in that file's header.
• Sites: directory is the primary input — it is auto-zipped (the only thing POST /api/sites accepts), which seals relative paths. A pre-built .zip is the alternative input, uploaded as-is. Always publish BUILT output (dist/, build/, out/, _site/, public/), never project sources.
• The auto-zip excludes .git/, .env/.env.*, node_modules/, editor/OS junk, sourcemaps and logs — a deliberate secret-leak safeguard so credentials and VCS history never reach the public archive.
• Entry file detection: --entry override > index.html > first .html alphabetically.
• SITE URL — NO trailing slash. API returns .link = "https://brewpage.app/public/<id>" without trailing /. Appending / routes to brewpage.app's own landing page; the JS redirect that rescues the no-slash form does NOT fire for the slash-dir form → site becomes inaccessible.
• SITE verification cannot be done via curl. The no-slash URL serves the BrewPage landing HTML with an inline JS redirect that only executes in a real browser. Verify with Playwright / browser_navigate, or fetch <url>/index.html explicitly.
