# Node apps
# Lazy-loading nvm
Since v3.1.44 it is possible to initialize nvm helper code on first-run thus improving shell load times. Set
~/.bashrc. A first-time invocation of
nvm will initialize nvm code, shimming the path as needed.
# Selecting Node versions
It is strongly recommended to select a Node version other than system default. LTS (opens new window) is typically recommended for maximum compatibility with packages on npm.
Example: changing Node versions:
# List remote Nodes nvm ls-remote # Install LTS release "boron" (6.11) nvm install lts/boron
# Memory allocation failure
Complex pipeline builds may fail with out-of-memory errors, e.g.
RangeError: WebAssembly.Instance(): Out of memory: wasm memory or
Fatal process out of memory: Failed to reserve virtual memory for process-wide V8 pointer compression cage.
This is related to a virtual allocation failure (nodejs/node#25933 (opens new window)) Removing the virtual memory limit, intended as a safety limit, resolves this issue.
