You can choose a specific version of Node.js. We mirror all published versions, which you can see in this repo at /nodejs/private/node_versions.bzl.
Now that Node 12 is LTS (Long-term support) we encourage you to upgrade, and don’t intend to fix bugs which are only observed in Node 10 or lower. Some of our packages have started to use features from Node 12, so you may see warnings if you use an older version.
Add to WORKSPACE:
nodejs_repositories(
node_version = "8.11.1",
)
If you’d like to use a version of Node.js that is not currently supported here,
for example one that you host within your org, you can manually specify those in your WORKSPACE:
load("@rules_nodejs//nodejs:repositories.bzl", "node_repositories")
nodejs_repositories(
node_version = "8.10.0",
node_repositories = {
"8.10.0-darwin_amd64": ("node-v8.10.0-darwin-x64.tar.gz", "node-v8.10.0-darwin-x64", "7d77bd35bc781f02ba7383779da30bd529f21849b86f14d87e097497671b0271"),
"8.10.0-linux_amd64": ("node-v8.10.0-linux-x64.tar.xz", "node-v8.10.0-linux-x64", "92220638d661a43bd0fee2bf478cb283ead6524f231aabccf14c549ebc2bc338"),
"8.10.0-windows_amd64": ("node-v8.10.0-win-x64.zip", "node-v8.10.0-win-x64", "936ada36cb6f09a5565571e15eb8006e45c5a513529c19e21d070acf0e50321b"),
},
node_urls = ["https://nodejs.org/dist/v{version}/{filename}"],
Specifying node_urls is optional. If omitted, the default values will be used.
You can use your own Node.js binary rather than fetching from the internet.
You could check in a binary file, or build Node.js from sources.
To use See nodejs_toolchain for docs.
