library0.9.13jsnpmunverified

PineTS is an open-source transpiler and runtime that executes Pine Script (TradingView's indicator language) in Node.js, browsers, and other JavaScript runtimes. Version 0.9.13 is the latest stable release, with active development and biweekly releases. Key differentiators include 1:1 syntax compatibility with Pine Script v5, support for multiple data providers (Binance, CSV, custom), and full TypeScript types. Unlike alternatives (e.g., pine-js), PineTS is a full runtime with a built-in transpiler and provider abstraction, enabling off-platform execution of indicators and strategies for backtesting, alerts, and ML pipelines.

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

PineTS

✓ import { PineTS } from 'pinets'

✗ const PineTS = require('pinets')

ESM-only. CommonJS require will not work.

Provider

✓ import { Provider } from 'pinets'

✗ import { Binance } from 'pinets'

Provider is an enum; access via Provider.Binance.

PineTS (default)

✓ import PineTS from 'pinets'

✗ import { default as PineTS } from 'pinets'

Default export is the same as named. Both work.

DataProvider

✓ import { DataProvider } from 'pinets'

For custom data sources; not needed with built-in providers.

PineScriptError

✓ import { PineScriptError } from 'pinets'

Type for errors thrown by Pine Script execution.

Initializes PineTS with Binance BTCUSDT 1h data and runs a simple EMA cross Pine Script, logging the first 5 values of each plot.

import { PineTS, Provider } from 'pinets'; const pineTS = new PineTS(Provider.Binance, 'BTCUSDT', '1h', 100); async function main() { const { plots } = await pineTS.run(` //@version=5 indicator("EMA Cross") plot(ta.ema(close, 9), "Fast", color.blue) plot(ta.ema(close, 21), "Slow", color.red) `); console.log('Fast EMA:', plots['Fast'].data.slice(0, 5)); console.log('Slow EMA:', plots['Slow'].data.slice(0, 5)); } main().catch(console.error);

Debug

Known issues

breakingProvider enum changed in v0.8.0: old string-based provider names (e.g., 'binance') no longer accepted. Use Provider.Binance.

fix

Replace provider strings with enum values: Provider.Binance, Provider.BinanceFutures, etc.

affects: >=0.8.0

breakingrun() method returns object with `plots` key instead of array since v0.9.0.

fix

Access plots via plots['name'] instead of destructuring from array.

affects: >=0.9.0

deprecatedUsing require('pinets') is deprecated as of v0.9.0. Package is ESM-only moving forward.

fix

Switch to ES module imports: import { PineTS } from 'pinets'.

affects: >=0.9.0

gotchaPine Script strings must use backticks or escaped quotes inside JavaScript strings. Template literals work best.

fix

Use backticks for multi-line Pine code to avoid escaping issues.

affects: all

gotchaData fetched from Binance may have gaps; ensure at least 100 bars for reliable indicator calculations.

fix

Request extra bars (e.g., 200) to account for missing data or warmup.

affects: all

gotchaPlot data is returned as arrays with the same length as the requested bar count; first elements may be NaN due to indicator warmup.

fix

Filter out NaN values or slice after warmup period (e.g., plots['SMA 20'].data.slice(20)).

affects: all

Errors

Common errors & fixes

Error: Cannot find module 'pinets'

Package not installed or wrong import path.

fix

Run 'npm install pinets' and ensure you're using ESM imports.

TypeError: Provider.Binance is undefined

Provider enum not imported correctly.

fix

Use 'import { Provider } from 'pinets'' and access Provider.Binance.

SyntaxError: Unexpected token 'export'

Using CommonJS require on an ESM-only package.

fix

Switch to ES module syntax or add 'type': 'module' in package.json.

PineScriptError: line X: ... (Pine script compilation error)

Pine Script syntax error (e.g., missing //@version=5).

fix

Check Pine Script code for errors and ensure version pragma is included.
