nodejs

In nodejs, lts means long-term support and is the abbreviation of "Long Time Support"; Node has two release process lines, odd version and even version. When an odd version is released, the latest even number The version will immediately enter the LTS maintenance plan, which will last for 18 months. After that, there will be an extended maintenance period of 12 months. During the LTS period, "bug fix" changes can be supported.

What does lts mean in nodejs

LTS means Long Time Support, which means long-term support.

LTS: Long-term support version, stable
Current: The latest version

Node is maintained There are two release process lines: odd-numbered versions are released in October every year, and even-numbered versions are released in April of the following year.

What does lts mean in nodejs

When an odd-numbered version is released, the latest even-numbered version will immediately enter the LTS maintenance plan, which will last for 18 months. There will then be an extended maintenance period of 12 months. The changes that can be supported during these two periods are different:

Changes supported during the LTS period: bug fixes, security issue fixes, documentation updates and updates with compatibility issues with future new features.

Changes supported during Maintenance: serious bug fixes, serious security issue fixes or documentation updates.

When an even-numbered version is released, the odd-numbered version only has a 2-month maintenance period and can only be upgraded obediently.

In summary:

Based on the minor version upgrade, the LTS and Maintenanece versions do not have radical new feature updates and are more suitable for the production environment. Upgrading the minor version requires regression workload and The risk will be much smaller. Based on the major version number upgrade, LTS and Maintenanece versions have a long maintenance life cycle and do not need to upgrade the main version number frequently. This is not the case for odd-numbered versions, which usually have to be upgraded once every six months.

Extended knowledge:

Node.js LTS plan

Node.js core After the merger of Node.js and io.js, In order to ensure a stable and orderly release and allow developers to reasonably arrange upgrades, LTS (Long Term Support) began to be used to plan the release cycle. The first LTS version was v4, released in October 2015.

Under this plan, the version of Node.js is equivalent to a snapshot of the master branch that has been stabilized at a specific time. When the time is up, the stable parts of the master branch will be integrated and a new version will be released. Therefore The release of Node.js is based on the passage of time, and the version jumps on the premise of ensuring close compatibility, rather than on the number of compatibility and new features. This also explains why the version of Node.js seems to jump. So fast (not "Ah, we have saved so many big moves, we can release a new version!" but "Ah, it's time to release a new version in April. Let's go through the big moves we have saved to see what is stable enough. Added in, although these tricks may not be that big...").

It is worth mentioning that the current Evergreen browser/mainstream JavaScript engine/ECMAScript standard/C standard also adopts similar principles, taking the time span as the benchmark, and intercepting stable features from the backbone for release .

Each LTS will have a code name. Take the element name from the periodic table, sort it alphabetically, and select the appropriate one. The code name of v4 is Argon (argon), and the code name of v6 is Boron (boron).

The version naming rules of Node.js follow Semantic Versioning. The version number is divided into three parts. The first number (semver-major) increases to indicate incompatible changes; the second number The number (semver-minor) increases, indicating that there are new features that maintain compatibility; the third number (semver-patch) increases, indicating that there are changes while maintaining compatibility and features, such as bug fixes or improvements. document. This naming rule has advantages and disadvantages, which will not be described here. However, some of its contradictions make some exceptions to the naming of Node.js. For example, even if a security update causes incompatibility, in order to be able to update to all major versions, it is still semver. -minor.
