3.8.2. Installing additional packages in Node.js
Node.js comes with a default package manager utility called npm. You can use this utility to install
additional Node.js modules. To use it, first make sure your board is connected to the internet as
described in section 4.6.5, "Connecting LinkIt Smart 7688 to a Wi-Fi Access Point To Access
Internet" or Get Started guide, and check
install command in the system console to install the packages. For example:
npm install request
This installs the popular
Note some NPM packages that rely on native C/C++ implementation may fallback to pure
JavaScript implementations or fail to install at all because there isn't native compilation
toolchain environment available on the board, specifically, the node-gyp. For example, when
installing the socket.io package, you'll see a warning message during the installation process, as
shown below:
sh: node-gyp: not found
npm WARN optional dep failed, continuing utf-8-validate@1.2.1
This is because socket.io relies on other packages such as utf-8-validate and bufferutil that
require node-gyp to build their native implementations. These are optional dependencies to
socket.io package, so eventually the package installs and you can still use it with some
limitation. But for some packages that require native implementations, they may fail to install at
all.
