uxLog Usage

uxLog writes to three sinks at once:

1. The terminal (via commandThis.ux.log or console.log).
2. The hardisLogFileStream file log.
3. The VS Code (LWC) UI over WebSocket - except when logType === "other", or the line contains the markers [command] or [NotifProvider].

The logType argument both labels the line in the UI (drives section grouping, icons, colors) and decides whether the line reaches the UI at all. Pick it deliberately.

Import

import { uxLog, uxLogTable } from "../../../common/utils/index.js";
import c from "chalk";
import { t } from "../../../common/utils/i18n.js";

Levels and colors (strict 1:1 pairing)

Always pair the level with its chalk color. Mixing them confuses the terminal output and breaks the convention used across ~2000 existing call sites.

Level	Chalk color	When to use
action	c.cyan	A new major step. Opens a new section / log group in the VS Code LWC UI. One per logical phase (e.g. "Querying", "Generating report", "Deploying metadata").
log	c.grey	Sub-detail beneath the current action. Counts, file paths, timings, intermediate state.
warning	c.yellow	Recoverable issue the user should review. Operation continues.
error	c.red	Failure or blocking issue. Operation is aborting or the result is unusable.
success	c.green	Confirmed successful completion of an operation, often the closing line of an action block.
other	none / c.grey / c.italic	Console + file only. NOT forwarded to the VS Code UI. Use for raw JSON dumps, verbose debug, or chatter that would clutter the UI session log.
table	(internal)	Used by uxLogTable only. Do not call uxLog("table", ...) directly.

Examples

// New phase - opens a UI section
uxLog("action", this, c.cyan(t("deployingMetadata", { metadata: name })));

// Detail under that action
uxLog("log", this, c.grey(t("foundFiles", { count: files.length })));
uxLog("log", this, c.grey(`- ${reportFile}`));

// Recoverable issue
uxLog("warning", this, c.yellow(t("missingOptionalConfig", { key: "slackWebhook" })));

// Failure
uxLog("error", this, c.red(t("deploymentFailed", { message: e.message })));

// Successful completion
uxLog("success", this, c.green(t("deploymentSucceeded", { org: targetOrg })));

// Debug payload that should NOT pollute the VS Code UI
uxLog("other", this, JSON.stringify(rawApiResponse, null, 2));

Pitfalls to avoid

• Do not use c.green with error, c.red with success, etc. The level and color must match.
• Do not use action for sub-details - that creates spurious sections in the UI. One action per phase, then log for everything underneath.
• Do not use log (which goes to the UI in grey) for noisy diagnostic output - prefer other.
• Do not omit chalk - every uxLog should be wrapped in the matching color so terminal output stays readable.

Sensitive logging (sensitive=true)

Pass true as the fourth argument when the line contains credentials, tokens, secrets, or any data that must not land in the file log or the VS Code UI.

uxLog("log", this, c.grey(`Authenticating with token ${token}`), true);

Behaviour:

• Terminal: shows the real text (so the user running the command can still see it locally).
• File log (hardisLogFileStream): writes the literal string OBFUSCATED LOG LINE.
• VS Code UI: sends OBFUSCATED LOG LINE. Exception: lines containing SFDX_CLIENT_ID_, SFDX_CLIENT_KEY_, or SFDX_CLIENT_CERT_ are sent as-is even when sensitive=true.

Use sensitive=true for any line that interpolates an access token, refresh token, client secret, password, or third-party API key.

VS Code / LWC UI suppression

The VS Code extension only renders lines whose logType !== "other" AND whose text does not include the markers [command] or [NotifProvider].

Practical consequences:

• For raw payloads, JSON dumps, or noisy progress that would overwhelm the UI session log, use uxLog("other", ...). The terminal and file log still receive it.
• The [command] and [NotifProvider] prefixes are reserved for internal command-execution and notification-provider lines that the UI handles through dedicated events; do not introduce new uses of those markers in unrelated code.
• Other [Marker] prefixes (e.g. [DORA], [sfdx-hardis]) are fine and are forwarded to the UI.

uxLogTable

For tabular output, do not hand-format a table inside uxLog. Use uxLogTable, which renders an aligned text table to the terminal/file log AND emits a structured table payload to the LWC UI.

import { uxLogTable } from "../../../common/utils/index.js";

uxLogTable(this, [
  { name: "Account", recordCount: 42, status: "ok" },
  { name: "Contact", recordCount: 17, status: "ok" },
], ["name", "recordCount", "status"]);

• Second arg: array of plain objects (rows).
• Third arg (optional): column order. Omit to use the keys of the first row.
• Booleans are auto-rendered as checkbox emoji via bool2emoji.
• The LWC UI receives a JSON payload truncated at 20 rows with a "truncated" indicator row appended when the dataset is larger.
