Swansea backed up their opening-day win at Manchester United with victory over battling Burnley at the Liberty Stadium.
Nathan Dyer's 23rd-minute goal saw off the Clarets but it was not without scare as Burnley dominated the second half and probably should have returned home to Lancashire with a point.
Danny Ings was a constant thorn in the Swansea defence and goalkeeper Lukasz Fabianski had to make an excellent second-half stop to deny David Jones and preserve the 1-0 success.
The hosts were unchanged following their shock victory at Old Trafford, with midweek signings Federico Fernandez and Tom Carroll not included in the matchday squad.
Burnley were also unchanged from their 3-1 home defeat to Chelsea as Sean Dyche's side attempted to put their first points on the Barclays Premier League board following their promotion from the Championship.
Swansea went close to taking a third-minute lead when Wayne Routledge's cross found Wilfried Bony 12 yards out.
The Ivorian's header seemed destined for the far corner of the net but Jason Shackell intervened with a precious header.
Burnley were not shy in coming forward and Ings was lively as he played off the burly frontman Lukas Jutkiewicz.
Ings volleyed over from just inside the box after Jonjo Shelvey had been dispossessed and then he reached the byline to cut back a cross which Fabianski was grateful to grasp with Jutkiewicz lurking.
Shelvey forgot about his earlier error to get Swansea moving with a raking 40-yard pass which released Routledge down the right.
Routledge sped past Kieran Trippier to deliver the perfect ball for Gylfi Sigurdsson but the Icelandic midfielder's shot lacked power and Tom Heaton held on.
But Heaton was beaten five minutes later as Ben Mee failed to intercept Sigurdsson's ball and Dyer advanced to beat Heaton inside his near post with a shot which raised question marks about the Clarets goalkeeper.
The goal settled Swansea down and Bony began to flex his considerable muscles but Burnley were well-organised and refused to yield too much space.
Sigurdsson volleyed over from the edge of the area following a poor clearance from Michael Duff, who was making his 500th career appearance, and Bony's weak shot was comfortably held by Heaton - but Burnley had no further alarms before the break.
Bony had another chance straight after the restart when Dean Marney's headed back pass fell into his path but he horribly miskicked as he bore down on goal.
But Burnley were still very much in the game and Jutkiewicz felt he should have had a penalty after more good work by Ings, although television replays showed Ashley Williams made contact with the ball.
Scott Arfield and Marney both saw wayward efforts fly wide and Ings' drive was deflected wide as the home crowd began to get restless.
And Burnley should have been level when Marney's 64th minute cross picked out the unmarked Jutkiewicz but the former Middlesbrough forward headed over.
Garry Monk had seen enough and sent on Bafetimbi Gomis and Jefferson Montero for Bony and Dyer - but Burnley were within inches of equalising when Ings found David Jones and his shot was saved by Fabianski, with the ball just evading Jutkiewicz at the far post.
Swansea almost released the pressure valve when Montero's cross was punched out by Heaton and Ki Sung-yeung's rising drive just cleared the crossbar.
Burnley continued to press in the final minutes just as they had done all half but Swansea held on to make it two wins from two games.
