MySQL2 Timeout
[mysql2] 连接池query 的封装，支持acquireTimeout 和queryTimeout 选项。
Installation
npm install mysql2 @7digital/mysql2-timeout
Usage
只需使用它代替 mysql2 并调用 connect 传递 queryTimeout 和 acquireTimeout 毫秒值。 如果没有通过，每个将默认为 10 秒。 所有其他选项将直接传递给 mysql2。
如果连接获取超时，将抛出 DatabaseTimeout 错误。
如果查询超时，将
- kill the connection
- attempt to kill the outstanding query in the background
- throw a
DatabaseTimeouterror
只暴露mysql2连接池promise接口。
Example
const database = require('@7digital/mysql2-timeout');
async function main() {
const db = await database.connect({
host: 'localhost',
user: 'root',
database: 'test',
queryTimeout: 5000,
acquireTimeout: 2000
});
await db.query('SELECT 1');
}
Developing
docker-compose run test
运行一次测试。
docker-compose run watch
当源或测试更改时运行测试。
MySQL2 Timeout
A wrapper for [mysql2] connection pool query to support acquireTimeout and queryTimeout options.
Installation
npm install mysql2 @7digital/mysql2-timeout
Usage
Just use this instead of mysql2 and call connect passing queryTimeout and acquireTimeout millisecond values. If not passed, each will default to 10 seconds. All other options will be passed directly to mysql2.
If connection aquisition times out, a DatabaseTimeout error will be thrown.
If querying times out, it will
- kill the connection
- attempt to kill the outstanding query in the background
- throw a
DatabaseTimeouterror
This only exposes the mysql2 connection pool promise interface.
Example
const database = require('@7digital/mysql2-timeout');
async function main() {
const db = await database.connect({
host: 'localhost',
user: 'root',
database: 'test',
queryTimeout: 5000,
acquireTimeout: 2000
});
await db.query('SELECT 1');
}
Developing
docker-compose run test
Runs the tests once.
docker-compose run watch
Runs the tests when the source or tests change.
