feat(cli): Codex-style auto-update prompt and `e2b update` command by devin-ai-integration[bot] · Pull Request #2007 · e2b-dev/E2B

devin-ai-integration · 2026-10-20T17:58:00Z

Summary

Replaces the passive simple-update-notifier box with a Codex-CLI-style updater (src/utils/updater.ts) that knows how the CLI was installed and can run the upgrade itself.

Install detection: detectInstallMethod(realpath(argv[1])) checks the path in this order:
- /Cellar/e2b/ → brew
- /_npx/ → other
- /.bun/install/global/ → bun
- /pnpm/global/ → pnpm
- /lib/node_modules/@e2b/cli/ or Windows %APPDATA%\npm\node_modules\@e2b\cli → npm
- anything else (local devDependency, repo checkout) → other, which only gets a notice
Upgrade commands:
- npm: npm install -g @e2b/cli@latest
- pnpm: pnpm add -g @e2b/cli@latest
- bun: bun add -g @e2b/cli@latest
- brew: brew upgrade e2b
Latest version: comes from the npm registry, or for brew installs from formulae.brew.sh/api/formula/e2b.json, because the formula lags npm (2.22.0 vs 2.22.2 today).
Cache: ~/.e2b/update-check.json stores { lastCheckedAt, latestVersion, dismissedVersion? } and is refreshed in the background every 20h. Startup reads only the cache and never waits on the network, so a new version shows up on the next run (same as Codex).
Startup prompt: shown before the command runs, only when stdin and stdout are TTYs. It is skipped for --version, --help, help, update, under CI, and when NO_UPDATE_NOTIFIER is set.
```
? Update available! 2.22.3 -> 2.23.0
❯ Update now (runs `npm install -g @e2b/cli@latest`)
  Skip
  Skip until next version
```
"Update now" runs the upgrade and exits with "Run your command again". The old code is already loaded, so the original command is not run.
Notice: when the prompt isn't shown (non-interactive, or install method other), a one-line notice goes to stderr after the command, only if stderr is a TTY.
e2b update: always fetches the latest version fresh and runs the detected upgrade. If it can't detect the install method, it prints the npm command as an example and exits 1.
Dependency: simple-update-notifier is removed.

Usage:

e2b update                     # upgrade via the detected package manager
NO_UPDATE_NOTIFIER=1 e2b ...   # opt out of checks and prompts

I'll fix CI failures and address comments from users with write access. I'll skip comments containing "(aside)".

TASTE.md compliance review (CLI-only PR, so the SDK-surface rules T-1–T-46 and T-54–T-74 mostly don't apply).

Checked: T-12 (acronym casing), T-43 (shell composition: spawn uses fixed argv arrays, nothing is interpolated, OK), T-47 (named default constants), T-49/T-50 (env-var config and empty-means-unset), T-56 (version imported from package.json, OK), T-62/T-63 (actionable error messages).

Violations: 3 rules, 4 inline comments

T-50: NO_UPDATE_NOTIFIER / CI are checked with !== undefined, so an empty value counts as set. Flagged in both index.ts and updater.ts. This also regresses from the old truthiness check.
T-47: the 5000 ms fetch timeout is a magic number in fetchLatestVersion.
T-62: e2b update doesn't tell the user what to do when the version fetch fails.

Not tied to a line / not counted:

T-49: NO_UPDATE_NOTIFIER isn't E2B_-prefixed. It's the existing cross-tool opt-out shared with update-notifier, and this PR keeps it, so I'm not counting it.
T-12: the new import * as packageJSON in commands/update.ts would be packageJson under the rule, but it copies the existing name in src/index.ts. Rename both together if at all.

+    process.env.NO_UPDATE_NOTIFIER !== undefined ||
+    process.env.CI !== undefined ||


T-50 — an env var set to the empty string means unset. !== undefined treats an exported-but-empty NO_UPDATE_NOTIFIER= (or CI=) as set, so a blank value silently disables the updater. The code this replaces used truthiness (process.env.NO_UPDATE_NOTIFIER ? …), so this is also a behavior change for anyone with an empty var in their shell profile.

Suggested change

process.env.NO_UPDATE_NOTIFIER !== undefined ||

process.env.CI !== undefined ||

!!process.env.NO_UPDATE_NOTIFIER ||

!!process.env.CI ||

devin-ai-integration · 2026-10-20T17:59:13Z

+    env.CI !== undefined ||
+    env.NO_UPDATE_NOTIFIER !== undefined ||


T-50 — same issue here: an empty CI= / NO_UPDATE_NOTIFIER= should count as unset, but !== undefined makes it suppress the prompt. Check truthiness so this matches the index.ts gate. (This also repeats isUpdaterDisabled() from index.ts; keeping one shared check would stop the two from drifting apart.)

Suggested change

env.CI !== undefined ||

env.NO_UPDATE_NOTIFIER !== undefined ||

!!env.CI ||

!!env.NO_UPDATE_NOTIFIER ||

+  fetchFn: typeof fetch = fetch
+): Promise<string> {
+  const url = method === 'brew' ? BREW_FORMULA_URL : NPM_REGISTRY_URL
+  const response = await fetchFn(url, { signal: AbortSignal.timeout(5000) })


T-47 — defaults go in named module constants, not magic numbers at the call site. UPDATE_CHECK_INTERVAL_MS already does this; the 5 s request timeout should too. Declare const UPDATE_CHECK_REQUEST_TIMEOUT_MS = 5_000 next to UPDATE_CHECK_INTERVAL_MS and use it here:

Suggested change

const response = await fetchFn(url, { signal: AbortSignal.timeout(5000) })

const response = await fetchFn(url, {

signal: AbortSignal.timeout(UPDATE_CHECK_REQUEST_TIMEOUT_MS),

})

+    try {
+      latestVersion = await fetchLatestVersion(method)
+    } catch (error) {
+      console.error('Failed to fetch the latest E2B CLI version:', error)


T-62 — error messages should be actionable and say what to do, not just what failed. This prints the raw error (including its stack) and leaves the user stuck. The other failure paths in this command already name the manual fallback; do the same here:

Suggested change

console.error('Failed to fetch the latest E2B CLI version:', error)

console.error(

`Failed to fetch the latest E2B CLI version: ${error instanceof Error ? error.message : String(error)}. Check your network connection, or update manually with \`${getUpdateCommandDisplay(method) ?? 'npm install -g @e2b/cli@latest'}\`.`

)
